Section 1 - General Description

The OMEGA®FLSC90-A Fiber Optic Flow Signal Conditioner/Transmitter has
been designed for use with the patented LIGHTSPEED

TM

Paddlewheel flow
Sensors and will provide a linearized output signal of 4 to 20 mAor 1 to 5 Vdc.
The output signal is scaled and directly proportional to the rate of flow
measured by the paddlewheel sensor when installed in a FP9000 SERIES
installation fitting. The transmitter is mounted in a die cast aluminum housing
(NEMA4 rated).

Section 2 - Unpacking

Remove the packing list and verify that you have received all your equipment. If
you have any questions about the shipment, please call our Customer Service
Department at

1-800-622-2378 or 203-359-1660. We can also be reached on the Internet at
www.omega.com
e-mail: [email protected]

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.

The carrier will not honor any damage claims unless all shipping material is saved for
inspection. After examining and removing contents, save packing material and carton in the
event reshipment is necessary.

The following following items are supplied in the box with your FLAC90-A.

• This Manual, #M-3586 (1 ea.)

• Fiber Optic Cable Sealing Washer (2 ea.)

• 249 Ohm Shunt Resister For Voltage Output Operation (1 ea.)

NOTE:

Section 3 - Theory of Operation

The FLSC90-A has been designed to interface directly with OMEGA’s FP9000
Series LIGHTSPEED

TM

Paddlewheel flow sensors. The FLSC90-A signal
conditioner/transmitter provides a high intensity light source to the patented
paddlewheel flow sensor through a semi-rigid, duplex, fiber optic cable.
Returning light pulses are measured and converted by the signal conditioner to
an analog output current or voltage output that is directly proportional to the
flow rate being measured by the paddlewheel.

Section 6 – Using the Fiber Optic Extension Cable (FLSC90-CA9)

Where in applications such, that the fiber optic sensor must be installed farther
than the attached duplex cable on the sensor will allow, an extension cable is
available (Omega Model No. FLSC90-CA9. This accessory extends the total
overall distance between the paddlewheel sensor and the signal conditioner to
18'. It is not recommended that more than one extension cable be used in your
application. The farther the fiber optic cable is extended, the less the sensors
ability to return light pulses that are high enough in amplitude for the signal
conditioner to process.

When measuring the flow of dirty, discolored, or cloudy liquids such as, oil, ink, milk or others, if possi­ble, the sensor cable should not be extended beyond the standard 9 feet and may also require to be
shortened for proper operation in such applications.

Section 8 – Transmitter Scaling

Your transmitter has been factory tested to meet or exceed the specifications
outlined in this manual. The FLSC90-A must be scaled to operate for the correct
sensor and fitting size you will be using it with to maintain original
specifications. This procedure below is for scaling your transmitter. It is
generally recommended that your transmitter be re-scaled on an annual basis
depending on operating conditions and usage.

Scaling Procedure:Calibration Frequencies

1. Calculate what your calibration frequencies you will be using in the procedure

and formulas below.

a. Find the K-Factor listed in figure Table A for the fitting you will be using, call

this "K"

b. Determine what your full scale flow rate will be in your application, call this

"MAX FLOW"

c. Using the formulas below calculate your "CAL MAX", "CAL LOW", "CAL

MID" and "CAL HIGH" frequencies.

CAL MAX = MAX FLOW x K

60

CAL LOW = CAL MAX x .25

CAL MID = CAL MAX x .50

CAL HIGH = CAL MAX x .75

2. Connect the FLSC90-A transmitter as shown in figure 9 (see next page) to the

power supply, multi-meter (set to measure milli-amps) and the frequency
simulator.

3. Apply power to the FLSC90-Atransmitter and allow the unit to warm-up for

10 min.

4. On SW1, (See figure 9), set switch #2 to the "OFF" position.

5. On SW1, using figure 9 as reference, set switch #4, 5 or 6 to the "ON" position

based on the "CAL MAX" frequency you calculated in "Step 1".

6. Turn the frequency calibrator to the "ON" position.

7. Set the frequency calibrator for a DC square wave (6.5 V In Amplitude)

output equal to the "CAL LOW" calculated in "Step 1".

8. On SW1, set switch #1 to the "ON" position.

9. Adjust the "ZERO" potentiometer (P1) until the ammeter reads 8.00 mA.

10. Set the frequency calibrator for an output equal to the "CAL HIGH"

frequency calculated in "Step 1".

11. Adjust the "SPAN" potentiometer (P2) until the ammeter reads 16.00 mA.

12. Set the frequency calibrator for an output equal to the "CAL MID" frequency

calculated in "Step 1", the output should read 12.00 mA±0.024.

13. Scaling complete.
