FP7002/FP7002A Flow/Temperature Transmitter

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.

NOTE

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

Page 6

FP7002/FP7002A Flow/Temperature Transmitter

materials. It can be used with non-flammable, non-hazardous liquids up to 5 centipoise viscosity, but field calibration is recommended for accurate measurements.

It is important to note that most process water contains dissolved minerals. If the flowsensor is repeatedly exposed to process water and then the line is allowed to dry, these dissolved minerals will deposit onto the FP7002 and will inhibit the low flowrate operation of the sensor. If this occurs, cleaning of the sensor is recommended.

CAUTION

WATER HAMMER AND SURGES CAN BE DAMAGING TO ANY FLOWMETER AND MUST ALWAYS BE AVOIDED.

WATER HAMMER OCCURS WHEN A LIQUID FLOW IS SUDDENLY STOPPED AS WITH QUICK CLOSING AND SOLENOID OPERATED VALVES. SURGES OCCUR WHEN FLOW IS SUDDENLY BEGUN, AS WHEN A PUMP IS TURNED ON AT FULL POWER OR A VALVE IS QUICKLY OPENED.

LIQUID SURGES ARE PARTICULARLY DAMAGING TO FLOWMETERS IF THE PIPE IS ORIGINALLY EMPTY. TO AVOID DAMAGING SURGES, FLUID LINES SHOULD REMAIN FULL (IF POSSIBLE) AND PUMPS SHOULD BE BROUGHT UP TO POWER AND VALVES OPENED SLOWLY. IN ADDITION, TO AVOID BOTH WATER HAMMER AND SURGES, A SURGE CHAMBER SHOULD BE INSTALLED.

2.3 Flowmeter Installation

The FP7002 can be mounted in vertical or horizontal pipe runs; however, the pipe must be full of liquid for proper readings. Thus, the sensor should not be mounted in vertical pipe where the liquid flows down, since the pipe may not always be full in this situation. Refer to Figures 2-1 and 2-2.

Page 7

Figure 2-1. Horizontal Mounting Position

FLOW

Figure 2-2. Vertical Mounting Position

Page 8

FP7002/FP7002A Flow/Temperature Transmitter

The FP7002 should not be mounted at the bottom of the pipe (the 6 o’clock position) because this is where sediment in the liquid will tend to accumulate. The best mounting location is at or near the 12 o’clock position, so long as bubbles are not present in the liquid. The 3 o’clock and 9 o’clock positions are also acceptable. In an upward flowing vertical pipe, the flowsensor can be mounted anywhere around the pipe.

As with many flowmeters, the FP7002 requires a fully developed flow profile in order to provide accurate readings. To insure this, a length of straight pipe run before and after the flowmeter is required. The amount of upstream straight pipe run that is required depends upon the type of obstruction which is immediately upstream of the flowsensor. See Table 2-1 for specific requirements. Downstream of the flowsensor, in all situations, only 5 diameters of straight pipe run is required, regardless of the downstream obstruction.

Table 2-1

UPSTREAM OBSTRUCTION

Concentric reducer 15 pipe diameters One elbow 20 pipe diameters 2 elbows, in same plane 25 pipe diameters 2 elbows, in two planes, 40 pipe diameters

or one expansion Valves, pumps*, same plane at least 50 pipe diameters, prefer sensor

mounted upstream

STRAIGHT PIPE RUN REQUIRED UPSTREAM OF PADDLEWHEEL SENSOR

*Oscillating or reciprocating pumps, which produce flow and pressure pulses in the flowstream, are not recommended for use with the FP7002 flowsensor.

NOTE

If you do not have the proper amount of straight pipe run available at your desired installation location, it is recommended to use flow straighteners to decrease the required straight run.

The paddlewheel must be aligned with the fluid flow; the installation fitting is supplied with an alignment tab which mates with a flat on the base of the paddlewheel sensor to insure proper sensor alignment. When using the PVC installation fitting, it is critical that the cap of the sensor is threaded onto the mating fitting HAND TIGHT ONLY; use of pipe wrenches, etc. on the plastic cap can lead to damage to the cap and/or the installation fitting.

Page 9

FP7002/FP7002A Flow/Temperature Transmitter

PANEL METER

The FP7002 has magnets installed in the rotating paddles; these magnets will tend to attract rust from the flowing fluid. Thus, it is NOT recommended to install the FP7002 in pipes which under typical conditions contain rust, such as in cast iron, black iron, carbon steel and other iron pipes (galvanized pipe has been treated to resist rust). In situations where rust can not be avoided, it is recommended to install a fine magnetic filter at least 50 pipe diameters upstream from the FP7002 and to periodically shut down the line and remove the sensor from the installation fitting for cleaning.

2.4 Electrical Connections

CAUTION

All electrical connections and wiring should be performed by suitably trained personnel only.

NOTE

To insure proper hook-up to your indicating device, the paddles of the FP7002 can be spun in the open air by blowing onto them before the sensor is installed into the installation fitting.

This is particularly important where the pipeline can not be conveniently shut down and the sensor removed after installation.

Section 3 - Maintenance

Except for intermittent removal of the sensor from the flow line for cleaning, there is no routine maintenance for the FP7002.

Section 4 - Calibration

4.1 Flow Calibration

Equipment Required:

12-18 Vdc Regulated Power Supply Frequency Generator/Calibrator (such as OMEGA Model: CL123) Multimeter (such as OMEGA Model: HHM290) Small jeweler’s type common blade screwdriver

Calibration Procedure:

1. Unscrew and remove the protection head cover.

2. Make wiring connections to the transmitter as shown on page 7.

3. Apply power and allow the unit to warm up for 10 minutes.

4. Determine the maximum volumetric flow rate expected by the application.

For our example we will use “GPM”. This will be “GPM Max”

5. From the table on page 8, determine the proper “K-Factor” for the model fitting you will be using.

6. Determine your full scale calibration frequency using this formula. This will be “F Max”.

Example: Using a Model FP7015 Tee Fitting with a K-Factor of 29.46

and a GPM Max of 125.

29.46 x 125 GPM = 61.38 for your F Max

7. Set your frequency generator for an output of 0 Hz. Adjust the zero potentiometer (P1) for a 4.00 mA output.

8. Set your frequency generator for the “F Max” you calculated above. Adjust the span potentiometer (P2) for a 20.00 mA output.

9. Set your frequency generator for one half the “F Max” you calculated above. You should have an output reading of 12.00 mA +/- 0.16 mA. If not, repeat steps 7 & 8.

10. Re-install 10 k resistor across terminals 5 and 6 and re-install white

wire to terminal 5.

11. Calibration complete.

F Max = K-Factor x GPM Max

4.2 Temperature Calibration

Equipment Required: 12-18 Vdc Regulated Power Supply

Type-K Thermocouple Probe (such as OMEGA Model: KTSS-HH) Multimeter (such as OMEGA Model: HHM290) Small potentiometer adjustment tool

Calibration Procedure:

1. Unscrew and remove the protection head cover.

2. Make wiring connections to the transmitter as shown on page 7.

3. Apply power and allow the unit to warm up for 10 minutes.

4. Place a reference temperature probe next to the body of the paddlewheel flow sensor with the unit removed from the flow line and lying on a work bench.

5. Connect the reference probe to a thermometer and allow the reading to stabilize for a few minutes. Record the reference probe reading as “Rtemp”

6. Calculate the correct current output that the transmitter should have for the ambient temperature your flow sensor and reference probe are exposed to using this formula.

0.16 x Rtemp + 4 = output setting

Example: If your reference probe is reading 23.4°C

0.16 x 23.4 + 4 = 7.74 mA

7. Adjust potentiometer P3 for the correct current output you calculated above.

8. Calibration complete.
