Safety instructions
Always observe and comply with the safety instructions, cautions and warning
notices.
2.1
The DURAG Ultrasonic Air Flow Monitor D−FL 220T is designed and built
using state of the art technology and complies with the recognised safety
regulations. Despite this, hazards can arise.
Therefore operate the product only when it is in perfect condition, and observe
the operating instructions. Any change to normal operation should be taken as
a serious indication of impaired functionality. In this regard, pay attention to:

emission of smoke or unusual smells,

excessive temperatures of system components,

the tripping of monitoring devices,

abnormal operating noises,

abnormal, strong fluctuations or shifts in the measurement results.
The D−FL 220T is not designed for use by private persons.
The D-FL220T is designed for use in areas that are identified by individual
guidelines, safety instructions, instructions and regulations.
Compliance with these instructions is a precondition for the operation of the
D−FL 220T. If local regulations or instructions vary from the provisions of these
operating instructions, so the stricter provisions shall be applicable.
The following warning and safety instructions apply in full to the D−FL 220T :

The statutory provisions applicable for the system and the technical
regulations implementing these provisions must be complied with during
preparation and performance of work.
D−FL 220T

Safety instructions
2.2
This device is powered by electricity. Therefore only appropriately qualified
personnel may work on it. These personnel must be thoroughly familiar with
all danger sources and repair measures in accordance with these operating
instructions.
WARNING!
Hazard due to electrical equipment
Before removal of any casings or guards, the devices must be deenergised and be
protected against unauthorised reconnection.

The devices may only be connected to the supply voltage indicated on the
type plate.

The devices may only be operated on a power supply that includes an
earthing contact. The protective effect must not be lost by use of a power
supply extension that lacks an earth conductor. Any discontinuity of the
earth conductor within or outside the device is dangerous and is not
permissible.

Cables must be routed so as exclude the possibility of a risk of accident by
persons stumbling over them or becoming entangled in them.
This measuring system has been designed to ensure strict segregation
between primary and secondary circuits. Low voltages that are connected
must therefore also be generated with strict separation.
CAUTION!
Electrostatic discharge (ESD) can damage electronic components
DURAG devices are protected against uncontrolled electrostatic discharge
(ESD) in closed operation. If the device is opened (e.g. for service or
maintenance work), then appropriate ESD protective measures must be
undertaken beforehand.
Electronic components are becoming increasingly smaller and more complex.
Their susceptibility to damage from electrostatic discharge is increased
accordingly. For all work on the open device, measures are to be taken
against electrostatic discharges for the protection of these components. For
prevention of static charging of the human body, service employees can for
example be equipped with a personal grounding system.

that has anything to do with the physical characteristics of the D−FL 220T
system.
3.1
The items delivered, according to the valid sales contract, are listed on the
shipping documents enclosed with the delivery. Check that the shipment is
complete and undamaged.
Report any sort of transport damage immediately to both the carrier and to
the DURAG GROUP. (for addresses see page 59 (DURAG GROUP
company addresses).
3.2
Transportation
The D−FL 220T is an electronic measuring device. As with all electronic
devices it must be handled with the necessary care. No special measures are
necessary during transport.
3.3
System description
The DURAG D−FL 220T measuring system continuously determines the flow
speed and the flow direction within road tunnels or exhaust ducts.
For this purpose two identical D−FL 220T M sensors send and receive
ultrasonic pulses in each direction. The transit time of the sound pulses is
dependent on the air flow occurring along the measuring path.
In each case the transit time is measured with and against the air flow. By
calculation the measured variables air speed, volumetric flow, flow direction
and air temperature are then determined.
In each case, two D−FL 220T M sensors constitute a measurement unit. One
sensor is configured as the master (A), the other as the slave (B). The master
(A) parameterises the slave (B), and controls its measuring operation. Master
(A) and slave (B) communicate via an internal bus.
A D−FL 220T system consists of:

D−FL 220T
2 × D−FL 220T M sensors.

2 × D−FL 220T BW wall brackets for erecting and aligning the sensors.

2 × D−TB100T terminal boxes (connection boxes, also called T-boxes for
short) for power supplies (24 VDC) and signal transmission between the
sensors and to the customer's interface.

3.4
3.4.1 Measurement sensors and wall brackets
The DURAG D−FL 220T measuring system (see Fig. 3.3) consists of two
identical D−FL 220T M sensors. Each D−FL 220T M sensor consists of the
sensor electronics and an attached ultrasonic converter. Each sensor is
mounted on a D−FL 220T BW wall bracket which is supplied. The mounting of
the sensor is described in section 4.4.1 from page 33.
The ultrasonic waves are emitted perpendicularly to the white face of the
ultrasonic converter. The white faces must be aligned to each other by adjusting
the wall brackets. The (imaginary) connecting line between the white faces
then runs perpendicularly through the centre of each face (see Fig. 3.1). Once
the sensors have been aligned to each other they can subsequently be
removed and refitted without requiring realignment.
The two D−FL 220T M sensors in a measuring system are identical.
Nevertheless it is essential that the one D−FL 220T M is configured as master
(A) and the other as slave (B). The configuration as "A" or "B" is determined
by the setting of a DIP switch on a circuit board within the sensor electronics
(see section 4.6.3 from page 42). To change this setting it is necessary to
open the device. The configuration can be factory set, which is indicated by
an "A" or "B" sticker on the casing of the device.
The loading of application-specific parameters (such as the installation
angle , tunnel width, output parameter settings) in the measuring system is
performed solely on sensor A. Sensor A saves the parameters that are input,
20
D−FL 220T
Product description
and synchronises the two sensors as a pair during operation (see Fig. 4.3
notes on page 33).
D−FL 220T system is provided via sensor A and the terminal box D−TB100T
associated with that sensor (see section 3.4.2) to the ventilation controller for
further processing.
The installation of the sensor is described in section 4.4.1 from page 33.

3.4.2 Terminal box
The terminal boxes (T-boxes) for the D−FL 220T system are available in two
versions.
D−TB100T A contains a 24VDC power supply unit and terminals.
D−TB100T P contains only terminals, but no power supply unit.
If the cable length from sensor A to sensor B is more than 50m, then sensor A
and sensor B must each be connected to a D−TB100T A. In this case each
D−FL 220T M has its own 24VDC power supply unit.
If the cable length from sensor A to sensor B is less than 50m, then sensor B
can alternatively be connected to a D−TB100T P. In this case a single
D−TB100T A supplies power to both D−FL 220T M sensors.
The cable length between sensor A and sensor B must not exceed 1000m.
Otherwise error-free data exchange between the sensors cannot be
guaranteed.
The entire cable length of the DURAG bus for data transmission from sensor A
to the control room, including any branches, must not exceed 1000m.

Fig. 3.5 Measurement principle
The D−FL 220T measuring system functions with two ultrasonic converters,
which each both send and receive a sonic signal. The measurement principle
is shown schematically in Fig. 3.5 . The ultrasonic sensors are mounted in a
tunnel so that the speed of the sound signal is influenced by the air flow, i.e.
the air flow must exhibit a vector component in the direction of propagation
of sound. The sensors are typically mounted at an angle of about 45° to the
axis of the tunnel (the permissible angular range is 30°...60°) (see section 4.3
from page 30). The basis for the calculation of the speed of the air flow is the
transit time of the acoustic pulses. The transit times yield the following
relationships:

The above calculations assume a uniform rate of flow at all points along the
measuring path. This assumption is an ideal which is not borne out in
practice. The real flow conditions are evaluated during commissioning. This
evaluation is incorporated into the parameterisation of the D−FL 220T M
sensor A. A correction function can then output the values for the D−FL 220T
based on the practical situation.
The correction uses the following function:
v corr  a0  a1  v  a2  v 2  a3  v 3
Equation
5
Parameters a0, a1, a2, a3 are determined by calibration or by modelling at
the time of commissioning.
The factory settings are:
a0 = 0; a1 = 1; a2 = 0, a3 = 0
The parameters can be input at the factory, during commissioning or after
calibration. The necessary tools are a laptop with a USB port, a USB cable and
the DURAG parameterisation software DESI 100.

Safety
DANGER
Risk of explosion with loss of life
The use of the Ultrasonic Air Flow Monitor D−FL 220T in explosion hazard
areas and its use for measurement of explosive gas mixtures is not
permissible!
WARNING!
Risk of electric shock
Improper use can lead to severe injuries. Once the housing or accidental
contact guards have been opened, live parts are accessible. When working
on the device, the mains power leads must therefore be disconnected and
secured against unauthorised reconnection. Any guards that were removed
must be replaced before switching on the mains power.
CAUTION!
Damage caused by unauthorised personnel
Improper use can result in severe damage.
Work on this device may only be carried out by appropriately qualified and
trained personnel.
CAUTION!
Also see "Qualified Personnel" on page 15.

For an understanding of how to select the measurement point, refer also to
section 3.6 Functional principle and measurement principle from page 24.
The selection of the installation location for the measurement sensor in the
road or railway tunnel is generally governed by the space available. Before
deciding on the installation locations, check whether the installation area may
be used by traffic.
The measurement system may be damaged if struck by passing traffic. We
recommend compliance with the dimensions shown in Fig. 4.1.
So as to avoid spurious measurement results, the measurement system
should not be installed:
 in the vicinity of ventilation inlets or outlets (min. 100 m distance),
 in the vicinity of axial fans (min. 100 m distance),
 in the vicinity of breakdown refuges or other changes in the tunnel crosssection (min. 100 m distance),
 in the vicinity of road signs or illuminated displays which could cause
turbulence in the flow of air (min. 20 m distance).

Fig. 4.5 Installation of the measurement sensors
1. Attach the first D−FL 220T M sensor to the wall bracket D−FL 220T BW by
tightening the twist lock  finger-tight (Fig. 4.5).
2. Slacken the screws  and  sufficiently that the device can be pivoted
vertically and horizontally in its bracket, against a degree of resistance.
3. Attach the laser pointer or laser distance meter to the ultrasonic converter so
that the laser beam is emitted perpendicular to the white face.
4. Align the D−FL 220T M sensor so that the light dot strikes the opposite
bracket. When the opposite bracket is 10 – 20 m away, the alignment is
correct when the light dot strikes within a radius of max. 1 m from the
installation point of the opposite bracket.
5. After aligning the sensor, tighten the screw  to permanently fix the
horizontal pivot angle. Tighten the screw  on the device to permanently fix
the vertical pivot angle.
6. Then repeat the procedure to align the second D−FL 220T M sensor.

Removing the sensors for servicing
1. Unlock the device plug at the terminal box and unplug it. Where there is a
cover cap hanging from the plug connection at the terminal box, screw it on.
2. Undo the twist lock  (Fig. 4.5) and remove the sensor from the bracket.
3. Screw the twist lock back into the sensor so that it does not become lost. The
twist lock is part of the D−FL 220T M sensor.
When the sensor is refitted after servicing there is no need to repeat the
alignment procedure. The alignment settings previously performed are
retained.
4.4.2 Installing the terminal boxes
The terminal boxes D−TB100T and D−TB100TP are installed close to the
measurement point (the connection cable to the measurement sensor is
approx. 1.5 m long). The dimensional drawing for the terminal box D-TB 100,
showing the positions of the attachment holes can be found on page 23 in Fig.
3.4.
Install the terminal boxes with the cable glands facing downwards! Seal any
unused openings against sprayed water!
Make sure the casing cover is the right way round (Fig. 4.6)! The casing seal
is not symmetrical in all directions. It the cover is fitted the wrong way round the
seal will be damaged and the terminal box will no longer achieve the Index of
Protection IP 66 (NEMA 4.4x).
If water penetrates inside the casing it can cause corrosion there and impair
the signal transmission.

WARNING!
must be replaced before switching on the mains
The electrical connection of the D−FL 220T system is performed within the
terminal box at a terminal strip Fig. 4.8 in accordance with the connection
diagram shown in Fig. 4.9 or from page 39.
The connection diagram can also be found on the cover of the respective
terminal box.
The cables for the power and data conductors should be laid separately.
SELV
This measuring system has been manufactured so that rigorous separation
between primary and secondary electric circuits is ensured. Low voltages that
are connected must therefore also be generated with strict separation.
The mains power supply cable should be 3 x 1.5 mm². Select the conductor
and sheath material to suit the conditions at the respective place of use. To
protect the supply conductor a 10A automatic circuit breaker should be
installed as near to the measuring system as possible. The individual
conductors in the mains supply cable should be secured in such a way that
they cannot touch neighbouring terminals whilst being disconnected (e.g.
using cable ties).
In all installations relating to the devices, ensure compliance with the applicable
VDE regulations and any supplementary regulations issued by the local power
supply companies.

4.5.1 Electrical connections to the terminal boxes
DANGER!
High voltage. Risk of fatal injury due to electrical power!
Once the device has been opened, live parts are accessible, carrying lifethreatening high voltages.
Touching such parts can lead directly to fatal injuries.

If there is any damage to the insulation, switch off the power and have it
repaired.

Before servicing, cleaning or repairing the device, disconnect the power
supply and secure it against reconnection.

Before removing any casings or guards, deenergise the devices and
check that they are dead.

Permit only electricians to work on electrical equipment.

Never bypass fuses or render them inoperative. When replacing fuses,
always comply with the correct amperage and the correct characteristics
(see rating plate).

Keep moisture away from live components. Moisture can lead to short
circuits.
Connection is made to the two D−TB100T terminal boxes as shown in Fig. 4.8
and Fig. 4.9.
The box for the D−FL 220T M sensor A (master) is always a D−TB100T A
terminal box. This type of terminal box contains a 24VDC power supply unit,
which supplies sensor A with power and can also supply sensor B with power.
Sensor B can be supplied with power by the terminal box for sensor A only if
the cable length between the two D−TB100T is < 50 m (assuming a cable with
0.5 mm² wire cross-section).
The box for the D−FL 220T M Sensor B can be either a D−TB100T A or a
D−TB100T P terminal box. The type D−TB100T P contains only terminals.

4.5.2 Making electrical connections to the measurement sensors D−FL 220T
Each measurement sensor is supplied factory-fitted with 1.5m long cable
terminating in a plug. The D−FL 220T M is connected by inserting the plug
into the socket on the terminal box. The socket on the D−TB100T is provided
with a protective cap to protect against the ingress of dirt. (Undo the protective
cap from the plug connector before inserting the plug).

Before installation, the parameters of the measurement sensor should be
set and checked.
The factory (pre-) settings of the sensor as master (A) or slave (B) is shown
by a sticker on the connection ring.
If the signals from the sensor are to the transmitted using the RS 485
interface, for instance to the control room, depending on the position of the
D−FL 220T M sensor on the bus a termination resistor should be activated or
deactivated. The factory setting is that this function is activated.
This section further explains the meaning of the LED indicator signals on the
lower face of the sensor casing.
4.6.1 Inputting parameters
To parameterise the measurement system, (only) the D−FL 220T M sensor A
(master) needs be connected to a PC. The parameterisation program
D−ESI 100 is installed on this computer. The connection is made using a
standard USB cable with a Mini-B 5–pin plug. This plug connector is inserted
into the base of the casing of the measurement sensor. Before doing this,
release and remove the cover cap from the base of the casing (e.g. with a
coin) (see Fig. 4.12).
Fig. 4.12 Cover cap for the USB connection
A separate manual supplied with the software explains how to use the
D−ESI 100 software.

4.6.3 Configuration switch S1
The measurement sensors are supplied already factory-configured. When a
D−FL 220T system is ordered, one sensor is configured as sensor A (master)
and the other as sensor B (slave). The sensors are labelled accordingly.
The DURAG bus terminating resistors are factory-set to "on". If additional
pairs of sensors are connected to a bus for measurement purposes (i.e. 4, 6,
8 or max. 10 sensors), the customer should ensure that only the last sensor A
in the series has its terminating resistor set to "on". All of the others must have
their DIP switch 3 set to "off". For the measurement sensors B (slave) there is
no need to change this switch setting, since it is pre-set to "off".
Fig. 4.13 Configuration switch S1
To open the blue sensor casing, undo the four 2.5 mm hexagon socket-head
screws. The configuration switch S1 is located on the rear of the circuit board
no. 3 (see Fig. 4.13). Set the switch to the setting as shown in Table 4.2.

If the circuit boards have come loose after the hood was removed, be sure not
to transpose the terminal strips on the circuit boards when plugging them in
again. Transposing the terminal strips can seriously damage the D−FL 220T .
To avoid damage arising due to leaks in the probe casing when closing the
casing:
 check the correct position of the seal before screwing it the two halves of
the casing back together.
 Remove any sand and dirt from the seal seating.
 Discard any seal that is defective or perished.
