Engineering hints
Orientation
• Recommended distance (1) wall – outer
edge of nozzle: ~1/6 of tank diameter.
Nevertheless, the device should not be
installed closer than 15 cm (6“) to the
tankwall.
• Not in the center (3), interference can
cause signal loss.
2
3
4
1
• Not above the fill stream (4).
• It is recommended to use a weather
protection cover (2) in order to protect
the transmitter from direct sun or rain.
Assembly and disassembly is simply
done by means of a tension clamp (see
Chapter 9 on page 81).

Mounting
Tank installations
• Avoid any installations (1), like limit
switches, temperature sensors, etc.,
inside the signal beam (see “Beam angle”
on page 20.
• Symmetrical installations (2), i.e. vacuum
rings, heating coils, baffles, etc., can
also interfere with the measurement.
1
a
Optimization options
• Antenna size: the bigger the antenna,
the smaller the beam angle, the less
interference echoes.
3
• Mapping: the measurement can be
optimized by means of electronic
suppression of interference echoes.
2
• Antenna alignment: “Optimum mounting
position” on page 25.
• Stilling well: a stilling well can always be
used to avoid interference.
• Metallic screens (3) mounted at a slope
spread the radar signals and can,
therefore, reduce interference echoes.
Please contact Varec for further information. Figure 4-8:

Tank Installations and Optimization
4.3.2.1 Measurement in a plastic tank
If the outer wall of the tank is made of a non-conductive material (e.g. GRP), microwaves can
also be reflected off interfering installations outside the signal beam (e.g. metallic pipes (1),
ladders (2), grates (3), …). Therefore, there should be no such interfering installations in the
signal beam.

4.3.2.3 Measuring conditions
Note
• In case of boiling surfaces, bubbling, or tendency for foaming, use the 7230 RTG or 7231
RTG. Depending on its consistence, foam can either absorb microwaves or reflect them off
the foam surface. Measurement is possible under certain conditions.
• In case of heavy steam development or condensation, the max. measuring range of the
7245 RTG may decrease depending on density, temperature, and composition of the
steam — use the 7230 RTG or 7231 RTG.
• For the measurement of absorbing gases such as ammonia NH3 or some fluorocarbons1),
please use the 7230 RTG in a stilling well.
1) Affected compounds are e.g. R134a, R227, Dymel 152a.

Figure 4-11: Measuring Conditions
• The measuring range begins, where the beam hits the tank bottom. Particularly with dish
bottoms or conical outlets the level cannot be detected below this point.
• In case of media with a low dielectric constant (groups A and B), the tank bottom can be
visible through the medium at low levels (low height C). Reduced accuracy has to be
expected in this range. If this is not acceptable, we recommend positioning the zero point
at a distance C (see Figure 4-11) above the tank bottom in these applications.
• In principle, it is possible to measure up to the tip of the antenna with the 7230, 7231, and
7240. However, due to considerations regarding corrosion and build-up, the end of the
measuring range should not be chosen any closer than A (see Figure 4-11) to the tip of the
antenna.
For the 7244 and 7245, the end of measuring range should not be chosen closer than A
(see Figure 4-11) to the tip of the antenna, especially if there is development of
condensation.
• The smallest possible measuring range B depends on the antenna version (see Figure 4-11).

• The tank diameter should be greater than D (see Figure 4-11), the tank height at least H
(see Figure 4-11).

4.3.2.4 Measuring range
The usable measuring range depends on the size of the antenna, the reflectivity of the medium,
the mounting location, and eventual interference reflections.
The maximum configurable range is:
• 20 m (65 ft) for the 723x RTG,
• 40 m (131 ft) for the 724x RTG (basic version),
• 70 M (229 ft) for the 724x RTG (with additional option 4, (see Section 3.2, "Scope of
Delivery" on page 8)
The following tables describe the groups of media, as well as the achievable measuring range
as a function of application and media group. If the dielectric constant of a medium is unknown,
it is recommended to assume media group B to ensure a reliable measurement.

For installations in a stilling well, follow the engineering hints on page 17 and note the following
points:
• Marker is aligned toward slots.
• Measurements can be performed through an open full bore ball valve without any problems.
4.4.3.3 Recommendations for the stilling well
At the construction of a stilling well, please note the following points:
• Metal (no enamel coating, plastic coating on request)
• Constant diameter
• Stilling well diameter not larger than antenna diameter
• Weld seam as smooth as possible and on the same axis as the slots
• Slots offset 180° (not 90°)
• Slot width respectively diameter of holes max. 1/10 of pipe diameter, de-burred. Length
and number do not have any influence on the measurement.
• At any transition (i.e. when using a ball valve or mending pipe segments), no gap may be
created exceeding 1 mm.
• The stilling well must be smooth on the inside (average roughness Rz  6.3 m). Use
extruded or parallel welded stainless steel pipe. An extension of the pipe is possible with
welded flanges or pipe sleeves. Flange and pipe have to be properly aligned at the inside.
• Do not weld through the pipe wall. The inside of the stilling well must remain smooth. In
case of unintentional welding through the pipe, the weld seam and any unevenness on the
inside need to be carefully removed and smoothened. Otherwise, strong interference
echoes will be generated and material build-up will be promoted.

For installations in a bypass, follow the engineering hints on page 17 and note the following
points:
• Marker is aligned perpendicular (90°) to tank connectors.
• Measurements can be performed through an open full bore ball valve without any problems.
4.4.4.3 Recommendations for the bypass pipe
• Metal (no plastic or enamel coating)
• Constant diameter
• Select horn antenna as big as possible. For intermediate sizes (i.e. 95 mm), select the next
larger antenna and adapt it mechanically (7230 and 7240 only).
• At any transition (i.e. when using a ball valve or mending pipe segments), no gap may be
created exceeding 1 mm (0.04").
• In the area of the tank connections (~ ±20 cm / 8“), a reduced accuracy of the measurement
has to be expected.

Operation
6.1.1
General structure of the operating menu
The operating menu is made up of two levels:
• Function groups (00, 01, 03, …, 0C, 0D): The individual operating options of the instrument
are split up roughly into different function groups. The function groups that are available
include, e.g.: “basic setup”, “safety settings”, “output”, “display”, etc.
• Functions (001, 002, 003, …, 0D8, 0D9): Each function group consists of one or more
functions. The functions perform the actual operation or parameterization of the
instrument. Numerical values can be entered here and parameters can be selected and
saved. The available functions of the “basic setup” (00) function group include, e.g.: “tank
shape” (002), “medium property” (003), “process cond.” (004), “empty calibr.” (005), etc.
If, for example, the application of the instrument is to be changed, carry out the following
procedure:
42
1.
Select the “basic setup” (00) function group.
2.
Select the “tank shape” (002) function (where the existing tank shape is selected).
6.1.2
Identifying the functions
For simple orientation within the function menus (see page 119), for each function a position is
shown on the display.

Displaying and Acknowledging Error Messages
6.4.1
Types of errors
Errors that occur during commissioning or measuring are displayed immediately on the local
display. If two or more system or process errors occur, the error with the highest priority is the
one shown on the display.
The measuring system distinguishes between two types of errors:
• A (Alarm): Instrument goes into a defined state (e.g. MAX 22 mA) indicated by a constant
symbol. For a description of the codes, see page 96.
• W (Warning): Instrument continue measuring, error message is displayed. Indicated by a
flashing
• E (Alarm / Warning): Configurable (e.g. loss of echo, level within the safety distance

HART Communication
Apart from local operation, parameterization of the measuring instrument and viewing
measured values by means of a HART protocol is also possible. There are two options available
for operation:
• Operation via the universal handheld operating unit, the HART Communicator DXR375.
• Operation via the Personal Computer (PC) using the operating program (e.g. ToF Tool or
FieldCare). For connections, see page 39.
Note The 7200 Radar Tank Gauge can also be operated locally using the keys. If operation
is prevented by the keys being locked locally, parameter entry via communication is not
possible either.

Commissioning
The basic setup is sufficient for successful commissioning in most applications. Complex
measuring operations necessitate additional functions that the user can use to customize the
RTG as necessary to suit specific requirements. The functions available to do this are described
in detail in the manual “Description of Instrument Functions  IOM069“.
Comply with the following instructions when configuring the functions in the “basic setup” (00):
• Select the functions as described on page 41.
• Some functions can only be used depending on the parameterization of the instrument. For
example, the pipe diameter of a stilling well can only be entered if “stilling well” was
selected beforehand in the “tank shape” (002) function.
• Certain functions (e.g. starting an interference echo mapping (053)) prompts the user to
confirm your data entries. Press + or - to select “YES” and press E to confirm. The function
is now started.
• If you do not press a key during a configurable time period ( function group
“display” (09)), an automatic return is made to the home position (measured value display).
Note The instrument continues to measure while data entry is in progress, i.e. the current
measured values are output via the signal outputs in the normal way.
Note If the envelope curve mode is active on the display, the measured values are updated
in a slower cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring point has been optimized.
Note If the power supply fails, all preset and parameterized values remain safely stored in
the EEPROM.
Caution! All functions are described in detail, as is the overview of the operating menu
itself, in the manual “Description of Instrument Functions  IOM069“.

A mapping is also possible by manual entry of the range to be suppressed. This entry is made
in the “range of mapping” (052) function.
Caution! The range of mapping must end 0.5 m (20") before the echo of the actual level.
For an empty tank, do not enter E, but E – 0.5 m (20").
Caution! If a mapping already exists, it is overwritten up to the distance specified in
“range of mapping” (052). Beyond this value the existing mapping remains unchanged.

optimizing the measuring point.
Note An orientation of the RTG can help to optimize measurement in applications with
very weak level echoes or strong interference echoes by increasing the useful echo/reducing the interference echo (see Section 9.5, "Orientation of the RTG" on page 102).

Maintenance
The 7200 Radar Tank Gauge measuring instrument requires no special maintenance.
8.1
Exterior Cleaning
When cleaning the exterior of measuring devices, always use cleaning agents that do not attack
the surface of the housing and the seals.
8.2
Replacing Seals
The process seals of the sensors must be replaced periodically, particularly if molded seals
(aseptic construction) are used. The period between changes depends on the frequency of
cleaning cycles and on the temperature of the measured substance and the cleaning
temperature.
Varec, Inc.

8.3
Repairs
The Varec repair concept assumes that the measuring devices have a modular design and that
customers are able to undertake repairs themselves. Spare parts are contained in suitable kits.
They contain the related replacement instructions. All the spare parts kits that can be ordered
from Varec for repairs to the 7245 RTG are listed with their order numbers on page 104.
Please contact Varec Service for further information on service and spare parts.
8.3.1
Repairs to Ex-approved devices
When carrying out repairs to Ex-approved devices, please note the following:
• Repairs to Ex-approved devices may only be carried out by trained personnel or by Varec
Service.
• Comply with the prevailing standards, national Ex-area regulations, safety instructions (XA)
and certificates.
• Only use original spare parts from Varec.
• When ordering a spare part, please note the device designation on the nameplate. Only
replace parts with identical parts.
• Carry out repairs according to the instructions. On completion of repairs, carry out the
specified routine test on the device.
• Only Varec Service may convert a certified device into a different certified variant.
• Document all repair work and conversions.
8.3.2
Replacement
After a complete RTG or an electronic module has been replaced, the parameters can be
downloaded into the instrument again via the communication interface. Prerequisite to this is
that the data were uploaded to the PC beforehand using the ToF Tool / FieldCare.
Measurement can continue without having to carry out a new setup.
• The user may have to activate linearization (see IOM069).
• The user may need to record the tank map again (see “Basic Setup” on page 57).
After an antenna component or an electronic has been replaced, a new calibration must be
carried out. This is described in the repair instructions.
84
8.4
Spare Parts
Note The user can order spare parts directly from your Varec’s service organization by
giving the serial number, which is printed on the measuring transducer nameplate
(see page 7). The corresponding spare part number also appears on each spare part. Installation instructions are given on the instruction card that is also delivered.

9.5
Orientation of the RTG
For orientation, a marker is found on the flange or threaded boss of the 7245. During
installation, this must be oriented as follows (see page 11):
• In tanks: to the vessel wall
• In stilling wells: to the slots
• In bypass pipes: vertical to the tank connectors
After commissioning the RTG, the echo quality indicates whether a sufficiently large measuring
signal is obtained. If necessary, the quality can be optimized later. Vice versa, the presence of
an interference echo can be used to minimize this by optimum orientation. The advantage of
this is that the subsequent tank mapping uses a somewhat lower level that causes an increase
in the strength of the measuring signal.
Proceed as follows:
Warning! Subsequent alignment can lead to personal injury. Before unscrewing or
loosening the process connection, make sure the vessel is not under pressure and does not
contain any injurious substances.
102
1.
It is best to empty the container so that the bottom is just covered. However, alignment can
be carried out even if the vessel is empty.
2.
Optimization is best carried out with the aid of the envelope graph in the display or the
ToF Tool/FieldCare.
3.
Unscrew the flange or loosen the threaded boss by half a turn.
4.
Turn the flange by one hole or screw the threaded boss by one eighth of a turn. Note the
echo quality.
5.
Continue to turn until 360° is reached.
6.
Optimum alignment:

Return
The following procedures must be carried out before a transmitter is sent to Varec for repair or
calibration:
• Remove all residue which may be present. Pay special attention to the gasket grooves and
crevices where fluid may be present. This is especially important if the fluid is dangerous to
health, e.g. corrosive, poisonous, carcinogenic, radioactive, etc.
• Always enclose a duly completed “Declaration of Contamination” form (a copy of the
“Declaration of Contamination” is included at the end of this operating manual). Only then
can Varec transport, examine, and repair a returned device.
• Enclose special handling instructions if necessary, for example a safety data sheet as per EN
91/155/EEC.
Additionally specify:
• An exact description of the application.
• The chemical and physical characteristics of the product.
• A short description of the error that occurred (specify error code if possible).
• If necessary, give the error code.

Effect of gas phase
High pressures reduce the propagation velocity of the
measuring signals in the gas/vapor above the fluid. This effect
depends on the gas/vapor and is particularly large for low
temperatures. This results in a measuring error that gets bigger
as the distance increases between the device zero point (flange)
and product surface. The following table illustrate this
measured error for a few typical gases/vapors (with regard to
the distance; a positive value means that too large a distance is
being measured). Refer to Table 10-10 on page 110 and
Table 10-10 on page 110 for details.

Depending on the length, this value can be reduced for Wave Guide
antennas. In the event of horizontal stress, mechanical support is
required or provide the Wave Guide antenna with a protective pipe.
Cleaning of the antenna
Depending on the application, the antenna can get contaminated. The
emission and reception of microwaves can thus eventually be hindered.
The degree of contamination leading to an error depends on the medium
and the reflectivity, mainly determined by the dielectric constant r. If
the medium tends to cause contamination and deposits, cleaning on a
regular basis is recommended. Care has to be taken not to damage the
antenna in the process of a mechanical or hose-down cleaning
(eventually connection for cleaning liquid). The material compatibility
has to be considered if cleaning agents are used!
The maximum permitted temperature at the flange should not be
exceeded.
Electromagnetic compatibility
•
Electromagnetic compatibility to EN 61326 and NAMUR
recommendation EMC (NE 21). For details, refer to the Declaration of
Conformity.
•
A standard installation cable is sufficient if only the analog 4-20 mA
signal is used. Use a screened cable when working with a
superimposed communications signal (HART).

Function and System Design
A.3.1
Function (measuring principle)
The RTG is a “downward-looking” measuring system, operating based on the time-of-flight
method. It measures the distance from the reference point (process connection) to the product
surface. Radar impulses are emitted by an antenna, reflected off the product surface, and
received again by the radar system.

Appendix
A.3.1.1 Input
The reflected radar impulses are received by the antenna and transmitted into the electronics.
A microprocessor evaluates the signal and identifies the level echo caused by the reflection of
the radar impulse at the product surface. The unambiguous signal identification is accomplished
by the PulseMaster® software, based on many years of experience with time-of-flight
technology.
The mm-accuracy of the 7500 Radar Tank Gauge could be achieved with the patented
algorithms of the PhaseMaster® software.
The distance D to the product surface is proportional to the time of flight t of the impulse:
D = c · t/2,
with c being the speed of light.
Based on the known empty distance E, the level L is calculated:
L=E–D
Refer to Figure A-3 on page 121 for the reference point for “E”.
The RTG is equipped with functions to suppress interference echoes. The user can activate these
functions. They ensure that interference echoes (i.e. from edges and weld seams) are not
interpreted as level echo.
A.3.1.2 Output
The RTG is commissioned by entering an empty distance E (=zero), a full distance F (=span) and
an application parameter. The application parameter automatically adapts the instrument to the
process condition. The data points “E” and “F” correspond with 4mA and 20mA for instruments
with current output. They correspond with 0% and 100% for digital outputs and the display
module.
A linearization with max. 32 points, based on a table entered either manually or
semi-automatically, can be activated locally or remotely. This function provides a measurement
in engineering units and a linear output signal for spheres, horizontal cylindrical tanks and
vessels with conical outlet.
A.3.2
Equipment architecture
A.3.2.1 Stand-alone
The 7245 RTG can be used for measurement in a stilling well/bypass as well as in free space.
The instrument provides a 4…20 mA output with HART protocol, or PROFIBUS PA respectively
FOUNDATION Fieldbus communication.
