Section 1 - General Description

The FP7002 flow/temperature transmitter is ideal for monitoring of 

typical industrial water flows and temperature, from hard-to-handle 

corrosive aqueous solutions to high purity fluids. The FP7002 uses a 

paddlewheel-like rotor whose motion is converted into a pulse output. 

This pulse output is converted to a 4 - 20 mA (or 1 - 5 Vdc) analog 

output by the built-in signal conditioner. A solid state temperature 

sensor built into the sensor body provides a separate 4 - 20 mA (or 

1 - 5 Vdc) analog output directly proportional to changes in fluid 

temperature. These independent analog outputs can be run long 

distances to a panel meter, controller or computer.
A complete flow measurement system consists of the flow sensor/

transmitter, the installation fitting and a readout device. The FP7002 

has polypropylene, 316SS, and FKM wetted parts. The schedule 40 PVC 

tee fittings are supplied with a PVC locking nut, and the galvanized 

iron tee fittings are supplied with a brass locking nut to provide a 

secure metal to-metal mounting to the threaded brass insert.

Section 2 - Installation

2.1 Unpacking

Remove the Packing List and verify that you have received all 

equipment. If you have any questions about the shipment, please call 

the OMEGA Customer Service Department.
When you receive the shipment, inspect the container and equipment 

for any signs of damage. Note any evidence of rough handling in 

transit. Immediately report any damage to the shipping agent.

  

N O T E

The carrier will not honor any claims unless all shipping 

material is saved for their examination. After examining 

and removing contents, save packing material and carton 

in the event that reshipment is necessary.

2.2 Important Considerations Before Installation

  

CAUTION

THE FP7002 PADDLEWHEEL FLOW TRANSMITTER IS NOT 

EXPLOSION-PROOF, NOR IS IT INTRINSICALLY SAFE. IT 

IS NOT TO BE USED FOR FLAMMABLE OR HAZARDOUS 

LIQUIDS, NOR CAN IT BE USED IN HAZARDOUS AREAS. 

The FP7002 is intended for use with water and other low viscosity 

liquids ONLY; it can NOT be used with oils and other viscous 

FP7002/FP7002A Flow/Temperature Transmitter
