Introduction
The INVALCO Turbine Flowmeter is a device used to measure the volumetric flow of a fluid. The flowmeter consists of
the body, a multiblade rotor (usually 6 to 10 blades depending on size), bearings and supports for the rotor. As a fluid
passes through the flowmeter the rotor spins. The speed of the rotor is directly proportional to the fluid velocity or flow
rate.
As the rotor spins, the balde tips pass through a magnetic field generated by permanent magnets in a pickup coil
mounted in close proximity to the rotor but separated from it and the process fluid by the wall of the flowmeter body.
Each time a blade passes the magnet, it generates a small alternating current in the pickup coil. (See Figure 7) The
pickup coil is attached to the pickup by two terminals or wires.
Each rotor blade passing through the magnetic pickup flux lines produce one alternating current cycle. Depending on
the flowmeter size, a certain number of pulses are produced for each volumetric unit of liquid passing through the turbine
flowmeter. This is known as the “K-Factor” of the turbine flowmeter. The variation of this factor over the specified flow
range is the Linearity or accuracy of the flowmeter.
Mechanical Installation
Turbine Flowmeters are affected by upstream and downstream piping configurations. Upstream piping has a
pronounced effect on flowmeter performance making it necessary to have ten (10) straight pipe diameters upstream of the turbine flowmeter and five (5) pipe diameters downstream of the turbine flowmeter. Flowmeters
should be installed with the arrow marked on the body pointing in the direction of flow.
Figure 1
Control valves should always be located downstream from the flowmeter. If a line is empty and a valve is opened, the
high velocity fluid stricking the flowmeter can cause severe damage. Air eliminators should be used in cases where
gases are flowing in the process stream. Air in the liquid will cause the flowmeter rotor to spin at a different rate than the
liquid giving incorrect readings.
Spools should be installed in the flowmeter position during start up to prevent damage to the flowmeter from solids
(welding slag, rust, scale, etc.) in the process liquid.
Note: Meter should be installed with ten diameters of straight pipe the same size as turbine meter bore
up and 5 straight pipe diameters downstream of meter.
Note: If valve is to be used, it must be downstream from the meter. This is necessary not only to keep the line
full for accuracy in batching applications, but to prevent damage caused by striking an empty meter with a
high velocity stream.
Note: Sleeved bearings used in INVALCO flowmeters are lubricated with the process fluid. Never spin
the flowmeter at high speeds with air. Always confirm that the flow line contains fluid at start up.
The life of the flowmeter can be extended by using a mesh filter in the flow line. Table I shows the recommended filter for
various sizes of flowmeters.

Installation (con’t)
Turbine Meter Maintenance
Electrical Installation (Figure 2)
Thread the magnetic pickup into the mounting boss
located on the top of the flowmeter. If the pickup does
not have wire leads included, connect the signal cable
to the pickup by threading on the keyed connector.
Note: Hand Tighten Only. Use of tools to tighten
the pickup can damage the flowmeter and pickup.
Removal of Flowmeter Internals
Cartridge Type Sizes 3/4 Inch through 2” (Figure 3)
The cartridge type turbine flowmeter utilizes internals assembled into a single part, eliminating the need for the three
part internals kit.
Note: This type of internals is not interchangeable with any
other body type.
1) Remove the magnetic pickup.
2) Identify the upstream end of the meter by locating
the
two grooves visible from the outside of one end.
3) Remove the retaining ring from the end of the flow
meter
identified by the grooves.
4) Slide the internals out of the flowmeter. It may be
necessary to push the internals out by gently applying
pressure to the opposite end.
5) Inspect the internal bore of the flowmeter for defects.
The internal surface of the flowmeter should be
smooth.
If the surface is damaged, the flowmeter
body should be
replaced.
6) Inspect the internals kit for damage or wear. If it appears
to be damaged, replace it with a new
internals kit.

Figure 2
Replacement of Flowmeter Internals
Cartridge Type Sizes 3/4 Inch through 2 Inch
1) Identify the upstream end of the turbine flowmeter by
locating the two grooves visible from the outside of one
end.
2) Identify the upstream end of the turbine flowmeter internals
by locating the end with a cone recessed between
two
supports forming a “V”.
3) Insert the end opposite of the recessed cone into the
groooves located in the upstream end of the turbine flow
meter body.
4) Slide the flowmeter internals into the turbine flowmeter
body until it seats firmly against the downstream end.
5) Insert the retaining ring into the upstream end of the turbine flowmeter, pushing it far enough into the flowmeter
body to engage the retaining ring slot directly above the
turbine flowmeter internals.

Removal and Replacement of Flowmeter Internals Size
4 Inch (Shipped Before April 1990) and Size 3 Inch
Shipped Before January 1989
1) Locate the flow direction arrow on the turbine flow
meter body, or the words “Inlet” or “Outlet” stamped
near the ends. Set the flowmeter body on end with
the outlet map.
2) Assemble the rear support assembly, giving attention to aligning the grooves in the pinion bolt with the
slots in the cage.
3) Install the lock washer and nut. The threads on the
pinion bolt should only extend halfway through the nut,
(about 2-1/2 turns).
4) Insert three vanes with the tapered bottom edges matching the sloping bottom of the grooves in the pinion bolt.
5) Locate the three wide and shallow grooves running in a
length-wise direction in the turbine flowmeter body.
6) Insert the support assembly into the body, bearing end
first, with the vanes sliding down the shallow grooves.
The assembly will come to rest against a shoulder.
7) Rotate the entire support assembly about 60 degrees,
so that the vanes are no longer lines up with the access grooves in the body.
8) Tighten the nut slowly, working the assembly back
and forth so the vanes will seat properly. Tighten the
nut secruely.
9) Turn the body over and slip the rotor onto the rear
bearing just installed.
10) Assemble and install the front support in the same
manner. It may be necessary to pull or push on the
pinion bolt to work the assembly in far enough to read
the shoulder, before rotating. The pinion bolt is pulled
back, the vanes are forced outward.
The rear pinion bolt can be identified by the 1/2 inch diameter carbide bearing which protrudes 1-7/32 inches.
The rear pinion body, or cage, can be identified as follows:
4 inch flowmeter front and rear cages are identical.
3 inch (shipped before January 1989) front cage overall
length is 2-21/32 inches and the slots begin 3/8 inches from
the open end.
Rear cage overall length is 2-15/16 inches and the slots
begin a little over 3/4 inch from the open end.
Removal of Flowmeter Internals
Size 4 Inch (Figure 5)
1) Remove the internals by retracting the set screw and rapthe sliding vane, if necessary, to relieve the locking pressure.
2) If spirolox rings are installed, remove them before attempt
ing to remove the supports.
3) Remove the rotor support fromt he flowmeter.
4) Remove the rotor from the flowmeter.
5) Repeat steps 1 through 3 to remove the second support.
Replacement of Flowmeter Internals
Size 4 Inch (Figure 5)
1) If your flowmeter body is grooved for spirolox rings, it is
recommended that the rings be installed.
Note: Lock rings are provided to absorb shock and
should be replaced when replacing the internals.
2) Advance the sliding vane with the set screw until the whole
support assembly fits closely in the bore of the flowmeter
body.
3) Position the support assembly against the shoulder in the
flowmeter body and tighten the set screw.
4) Install a spirolox ring if a groove has been provided for.
5) Meter bodies shipped after December 1, 1970 have three
grooves machined in each end. The sliding vane has an
“ear”, detail “B”, to engage one of these grooves. The front
support assembly should be positioned so that the sliding
vane engages the upper-left-hand groove. The sliding vane
on the rear support should engage the upper-right-hand
groove. Both sliding vanes should be in line.
6) For installation in older bodies (prior to December 1, 1970),
which are not grooved, the sliding vane can be turned
upside down (Figure 5) so the ear is buried in the support.

Magnetic Pickups
Flow in the turbine flowmeter is sensed by a non-wetted sensor called a variable reluctance magnetic pickup. The
magnetic pickup is an assembly consisting of a permanent magnet and a coil bobbin on which several hundred turns of
wire are wound (Figure 6). This combination produces a magnetic field at the top of the pickup. The pickup is placed in
close proximity to the rotor blades, but is separated from it and the process fluid by the wall of the flowmeter housing. As
the rotor turns, the blades disrupt the magnetic field of the pikcup and generate a sine wave voltage signal across the
terminals of the magnetic pickup coil. Each time a rotor blade passes through the magnetic field, one alternating current
(AC) cycle is generated (Figure 7). The number of pulses produced by a turbine flowmeter per gallon of water is known
as the “K-Factor”.

3-A Sanitary Meters/Internals
The INVALCO 3-A (28-03) Sanitary Turbine Flow meter is certified for use in the food and beverage industry where
3-A is required. The meter has been specially designed to have the same characteristics, flow ranges, and life as
all the Invalco industrial meters, and also meet or exceed the requirement of 3-A (28-03). The meter has a
maximum surface finish of 32ra on all internal parts; all components are manufactured out of 3-A approved
material, and can be cleaned in place to save time and money in disassembling cleaning and reassembling the
meter. The wear surfaces are made from FDA (3-A) approved carbide for superior wear resistance.
The meter can be cleaned as long as the following conditions are met:
! Caustic solutions that are acceptable with 316 stainless steel components
! Temperatures of less than 275ºF (135ºC) for less than a 60 minute duration
! Instantaneous flow Ranges of the fluids must never exceed the chart below.

Radii at ends of meters and the thrust bearing pockets (see figure 14) must be periodically checked for
cleanliness and adjustments in cleaning may be required to clean these areas. If areas do not clean in place
the meter may need to be disassembled from the line and cleaned by hand or other method to insure proper
cleanliness is being achieved. If the meter is disassembled for cleaning or inspection, care must be
taken not to lose the thrust bearings located at either end of the shaft. All replacement internals utilize a
sanitary paste to ensure that the bearings remain in place during assembly.

Operating Mode
The Model 4200 Rate Totalizer will display:
Total
Rate
Totals greater than 999,999 are viewable by pressing
the “Enter/Next” button. The roll over total screen displays a “r” in the left most position and then any digits
in excess of the six that are normally viewable.
K-factor is viewable by pressing the k-factor button on
the keypad, and pressing the k-factor button again will
return to the Totalizing display.
Software Version is viewable by pressing the “+” button on the keypad
Program Steps
1. Hold the “Program” button for 5 seconds. This will
put the 4200 into programming mode.
2. The first time that the 4200 is setup, the program
will take you directly to the K-factor entry screen. The
4200 will now prompt for using a single K-factor or to
linearize using multiple K-factors. Selecting “oFF” will
use a single K-factor (go to Step 3). Selecting “on” will
allow the input of multiple K-factors (go to Step 4).
Button operation:
“Program” = progress to next screen regardless of
where cursor is positioned
“Enter/Next” = move cursor left one position
“K-factor” = move cursor right one position
“+” = increments number where cursor is positioned
“-” = decrements number where cursor is positioned
“Reset” = replaces numbers with default and returns
the cursor to the right most position
3. Input the appropriate K-factor. Insertion of the
decimal position is the last step required to
input a new k-factor. After the last numerical
position is entered, the “+” and “-” buttons will
move the decimal position through the 3 positions. After placing the decimal in the correct
position, the “Enter/Next” button will progress
the screen. If linearization is required proceed
to Step 4. If linearization is not required proceed to Step 7.

Button operation:
“Reset” = replaces numbers with default and returns
the cursor to the right most position
4. Input the 1st pulse rate (Hz) starting with the lowest.
Button operation:
“Reset” = replaces numbers with default and returns the
cursor to the right most position
5. Input the 1st k-factor matching the 1st pulse rate
entered in the previous step. Insertion of the decimal position is the last step required to input a
new k-factor. The decimal position is limited to 3
positions. After the last numerical position is
entered, the “+” and “-” buttons will move the
decimal position through the 3 positions. After
placing the decimal in the correct position, the
“Enter/Next” button will progress the screen.
Button operation:
“Program” = progress to next screen regardless of where
cursor is positioned
“Reset” = replaces numbers with default and returns the
cursor to the right most position
6. Repeat step 4 and 5 for as many different pulse
rate and k-factor combinations up to 10 entries. If
you have less than 10 combinations to enter, enter
“000000” in the next pulse rate prompt to finish
combination entry. If you have 10 combinations,
after you enter the last k-factor the 4200 will go to
the next screen.

7. Set how many decimal positions you want in
the flow rate display.
000000 = no decimal positions
00000.1 = one decimal position
0000.02 = two decimal positions
000.003 = three decimal positions
0000-.1 = flow rate x 10
0000.-2 = flow rate x 100
Button operation:
“Program” = progress to next screen
“Enter/Next” = progress to next screen
“K-factor” = no action
“+” = increments amount of decimal positions
“-” = decrements amount of decimal positions
“Reset” = replaces default
8. Set how many decimal positions you want in
the total display.
000000 = no decimal positions
00000.1 = one decimal position
0000.02 = two decimal positions
000.003 = three decimal positions
Button operation:
“+” = increments amount of decimal positions
“-” = decrements amount of decimal positions
9. Set the time scale in which that the flow rate
will be displayed on the display.
10. Select “on” for a scaled pulse output. Select
“oFF” if a scaled pulse output is not desired (go
to Step 13).
Button action:
“+” = toggle between “oFF” and “on”
“-” = toggle between “oFF” and “on”
11. Set the scale of the scaled pulse output.
_____1 = 1 pulse per 1 increment of least significant
digit in total LCD
____10 = 1 pulse per 10 increment of least significant
digit on total LCD
___100 = 1 pulse per 100 increment of least significant
digit on total LCD
__1000 = 1 pulse per 1000 increment of least significant
digit on total LCD
_10000 = 1 pulse per 10000 increment of least significant digit on total LCD
100000 = 1 pulse per 100000 increment of least significant digit on total LCD
Button operation:
“+” = increments scale of pulse output
“-” = decrements scale of pulse output
12. This option is not operable or available for the
battery powered 4200. Verify that “oFF” is displayed. To select “oFF” push the “+” or “-” key and
go to Step 13.
SEc = unit of volume per second
60 SEc = unit of volume per minute
PEr hr = unit of volume per hour
24 hr. = unit of volume per day
Button operation:
“+” = increments unit of time scale
“-” = decrements unit of time scale

13. At this point the user has the option to establish a
password. Once a password has been set, the 4200 will
always prompt the user for a password, before program changes can be made. When no password or the
wrong password is entered, the 4200 will go back to
the normal display. THE ESTABLISHMENT OF A
PASSWORD IS OPTIONAL. If locking the 4200 with a
password is not needed, enter “000000” and the 4200
will operate unlocked. **
Button operation:
“Reset” = replaces numbers with default and returns the cursor to the right most position
** It is highly recommended that the
password function not be used unless it
is required. If a password is required
write down the password in the manual
and keep in a secure location. If you
forget the password you must consult the factory for procedures on
how to reset the current password.
14. Now the 4200 will prompt for user to accept
the password. Display should read 000000 in RATE
area of LCD if no password is required
Changing Batteries
New batteries can be purchased through INVALCO or
our distributors and replaced in the field.
WARNING - To prevent ignition of flammable or
combustible atmospheres, read, understand, and
adhere to the manufacturer’s live maintenance procedures.
Replace battery with an INVALCO battery assembly
ONLY. Battery assembly part number is P524017. The
model 4200 is designed to operate on one battery.
NEVER attempt to power the unit with two battery assemblies or with a non-INVALCO battery assembly.
There is one Lithium battery pack in each instrument and
care must be taken to replace so that there is always power
connected to the memory. Connect the new battery pack
into J3 or J4 before disconnecting the old battery. Failure to
not supply the board with continuous power will result in loss
of setup parameters and totals. Please dispose of old
batteries by sending them to an Approved Battery
Recycle Location.

Flowmeter Input
The Model 4200 input circuit which will accept signals
from most pulse or frequency producing flowmeters.
The input will interface directly to:
Turbine Flowmeters
For flow meters with coils, the minimum input voltage is
20mV P-P. See the drawing below and sketches on the
next two pages for hook-up information.
1. Squarewave, CMOS or Pulse
2. Reed or Switch
5. Coils (Magnetic Pick-up)

The 4200s are affected by EMF (Electric Magnetic
Fields); due to this the unit needs to be located in an
area with little affects from externally omitting EMF
devices. The turbine and pickup uses EMF in pulses
to calculate rate. Interference in this field by other
devices will cause inaccuracies with the meter. Electric motors, spark driven engines, transformers, and
other high current or high voltage devices create EMF
and should be kept as far away as feasible to lessen
their chances of effecting the meter.
Vibration can cause false readings or counted rate
when not in use. Portable units should be reset after
transport to re-zero the meter. Place meter in a location where it is well grounded, free of vibration and
stable when metering.
Installation
Wall Mounting
A wall mounting bracket is supplied with each instrument.
The instrument is then attached to the bracket at
the bottom with knobs.
Removing the Front Panel:
The front panel of the instrument is removed as follows:
1. Loosen knobs and tilt unit down.
2. Undo the eight screws retaining the front panel.
3. Pull the front panel free from the housing.
Unit can then be tilted up to access internal components.
