I. INTRODUCTION

The FLR Flow Transmitter is a state-of-the-art, micro­processor based variable area flow meter. It combines
the rugged proven technology of a piston-type,
variable area flow meter with solid state circuitry
including:

• Non-contact sensor electronics

• Electronic signal conditioning circuit

• Digital flow rate and total indication

• Proportional analog output

The product is sealed against industrial contamination
by a NEMA 12 and 13 (IP 52/54) rated enclosure and
is available for either liquid or gas service.

The FLR Flow Transmitter is capable of calculating and
displaying both flow rate and total accumulated flow.
The flow rate and total flow can be displayed in any of
the user selectable measurement units. The monitor’s
large 8 digit numeric liquid crystal display makes
extended range viewing practical. The second 8 char­acter alphanumeric display provides for selectable
units viewing in RUN mode and prompts for variables
in PROGRAM mode.

All FLR Flow Transmitters come pre-calibrated from the
factory. However, the unit may be adjusted by the user
to meet specific system requirements. Calibration
parameters are included for:

• Specific gravity compensation (water or
petroleum-based fluids)

• Pressure and temperature compensation
(pneumatic applications)

All meters include an analog output that can be config­ured for 0–5 Vdc, 0–10 Vdc, or 4–20 mA current loop.

Applications for the FLR Flow Transmitter include:

• Bearing lubrication

• Case drain verification

• Gun drill and machine cooling

• Pump flow outputs

Disconnect electrical power before opening wiring enclo­sure. Failure to follow these instructions could result in
serious personal injury or death and/or damage to the
equipment.

WARNING

This standard transmitter is unidirectional. Attempts to flow
fluids in the opposite direction of the flow arrow will result in
the meter acting as a check valve, creating a deadheading
situation. If the differential pressure magnitude is great
enough, damage to the internal parts of the meter will result.

CAUTION

This transmitter may contain residual amounts of test fluid at
the time of shipment. This fluid should be removed prior to
installation as the fluid may be incompatible or hazardous
with some liquids or gases. Failure to follow these
instructions could result in damage to the equipment.

CAUTION

Air/gas transmitters are NOT oxygen cleaned. Use
with oxygen may cause hazardous or explosive con­ditions that may cause serious personal injury and/or
equipment damage.

CAUTION

All wiring should be installed in accordance with the
National Electrical Code and must conform to any
applicable state and local codes. Failure to follow these
instructions could result in serious personal injury or death
and/or damage to the equipment.

Installation Recommendations

The transmitter is a simple device to install. However,
the following measures are recommended for reliable,
trouble-free operation:

DO - Align pipe accurately. Piping should be accurate­ly aligned and of correct length. The high pressure
body of the transmitter can withstand shock and
flow/pressure pulsation. However, the piping should be
firmly supported by external mounting brackets, both
upstream and downstream of the meter, to avoid any
pipe flexing action that could reduce meter life.

DO - Use rigid mounting. If the transmitter inlet or out­let are to be rigidly mounted, and the opposing port is
to be connected to flexible hose, the end connected
with the flexible hose must be rigidly mounted.

DO - Use Teflon®tape for sealing NPT fittings.

DO - Install unions. Install a union near the inlet or

outlet of the transmitter. This will facilitate quick, easy
removal and inspection during periodic maintenance
procedures.

DO - Ensure the fluid is traveling in the direction of the
flow arrow (Figure 5 on page 6).

NOTE: The FLR Flow Transmitter display board can be
rotated 180

°

for optimal viewing. Simply remove the
FLR Flow Transmitter cover, disconnect the ribbon
cable, rotate the display board 180

°

, reconnect the rib­bon cable, and reinstall cover. See Figure 8 on page 7
for cover screw tightening sequence.

DO - Use at least a 200 mesh (74 micron) filter. The
transmitter will allow particulate to pass that would jam
most valves and flow controls. Systems that do not
have filtration should be equipped with at least a 200
mesh (74 micron) filter. Most hydraulic systems
already have much finer filtration. Dirt, ferrous metal or
sealing agents, such as Teflon tape may lodge and
cause malfunction. If the transmitter is jammed at a
fixed position, follow cleaning and maintenance
instructions. See Maintenance section on page 14.

DON’T - Use thread locking compounds as thread
sealant.

DON’T - Install the transmitter near turbulence pro­ducing fittings such as elbows, reducers, close cou­pled valves, etc. The transmitter does not require flow
straighteners or special lengths of straight inlet/outlet
piping to stabilize turbulent flow patterns. However, to
assure maximum operational reliability, avoid installa­tion of elbows, valves and/or reducers immediately
adjacent to the transmitter inlet.

DON’T - Install the transmitter near fast-acting valves.
Fast-acting valves have the potential to create high
magnitude hydraulic pressure spikes. These spikes
can damage the internal components of the transmit­ter, resulting in inaccuracies or malfunction.

DON’T - Allow unidirectional transmitters to be
operated against the direction of the flow arrow. The
standard transmitter is a unidirectional flow transmitter.
The piston acts as a check valve to block flow in the
reverse direction. This causes an excessive pressure
differential, which can result in damage to internal
transmitter components. The transmitter is also avail­able in a modified design, which offers a reverse flow
bypass feature to accommodate bi-directional flow.

NOTE: Transmitters with a reverse flow bypass
feature are available. Consult factory for details.

Electrical Connections

Cable may be shortened or lengthened as required by
installation. The cable is soldered directly to the
electrical connector at the factory.

Cable replacement requires disassembly of the
electrical connector.

V. MAINTENANCE

Cartridge Cleaning (Figure 4 on page 5 and
Figure 9 on page 15)

1. Disconnect the transmitter cable.

2. Remove the transmitter from the line. Remove
excess piping from transmitter.

NOTE: It is not necessary to remove the aluminum
housing from the transmitter to remove it from the line.

3. Thoroughly wipe off the entire transmitter sur­face using mild detergent or isopropyl alcohol.

4. Remove the inlet port cap, wave spring, retain­ing ring, and cone assembly from the transmitter
body (Figure 9 on page 15).

5. Gently push the body towards the outlet port.

6. The piston, inner magnet and transmitter spring
are secured within the transmitter body with a
retaining ring. Remove the retaining ring with a
small screwdriver, then the internal components
can be removed from the body (Figure 9 on

page 15).

NOTE: If internal parts do not slide freely from
cartridge, use a wooden dowel inserted into the outlet
port of the transmitter to push parts out.

7. Place all parts on a clean work surface. Clean
and inspect all parts. Replace any that appear
worn or damaged.

Check inlet port O-ring for damage and replace
if required.

8. Reassemble the transmitter by inserting the
transmitter spring into the body, followed by the
piston/inner magnet assembly. A slight compres­sion of the piston against the spring is required
during installation of the retaining ring.

9. Gently push body assembly into the outlet end
of the transmitter enclosure. The flat surface of
the body outlet port should be flush with the
transmitter enclosure opening.

10. With the transmitter positioned vertically on a
flat surface, inlet port facing up, install the trans­mitter cone assembly and wave spring into the
body and secure with the inlet port end cap.

11. Reinstall transmitter to the line. Reconnect elec­trical power.

FLR Flow Transmitter

Installation & Programming Instructions

Page 14

Before attempting to remove the transmitter from the
line, check the system to confirm that line pressure
has been reduced to zero PSI. Failure to follow
these instructions could result in serious personal
injury or death and/or damage to the equipment.

WARNING

Always disconnect the primary power source before
opening the enclosure for inspection or service.
Failure to follow these instructions could result in
serious personal injury or death and/or damage to
the equipment.

WARNING

Do not use aromatic hydrocarbons, halogenated
hydrocarbons, ketones, or ester based fluids on
polycarbonate lens. Failure to follow these
instructions could result in damage to the transmitter.

WARNING

Inspection

1. Frequent inspection should be made. The envi­ronment and frequency of use should determine
a schedule for maintenance checks. It is recom­mended that it should be at least once a year.

2. Perform visual, electrical, and mechanical
checks on all components on a regular basis.

3. Visually check for undue heating evidence such
as discoloration of wires or other components,
damaged or worn parts, or leakage evidence
such as water or corrosion in the interior.

4. Electrically check to make sure that all connec­tions are clean and tight and that the device is
wired properly.

VI. TROUBLESHOOTING

No LCD display

• For 4–20 mA operation, check for current flow in
the loop.

• Check polarity of the current loop connections
for proper orientation.

• For 0–5 V or 0–10 V operation, check for proper
voltage being supplied to the unit.

• Check polarity of the supply voltage.

No rate or total displayed

• Check flow meter cone for debris. Cone should
move inside the tube freely.

• Check setup programming of flow meter.

Unstable Flow Reading

• This usually indicates pulsing or oscillation in the
actual flow. Increase the DAMPING parameter
to increase the filtering in order to provide a
more stable display reading.

VII. APPENDIX

Application Information – Liquid
Viscosity Effect (SUS/cSt)

The design utilizes a precision machined, sharp-edged
orifice and biasing calibration spring that assures
operating stability and accuracy over the wide viscosi­ty range common to many fluids. Generally, high flow

models of each transmitter size provide good accuracy
over a viscosity range of 40 to 500 SUS (4.2 to 109
cSt).

Density Effect (specific gravity)

Any fluid density change from stated standards has a
proportionate effect on transmitter accuracy.
Corrections for more or less dense fluids can be made
to standard scales using the following correction fac­tor:
