Finish Thompson FMBC2000 Series - Manual (Page 4)

Section 1 - Installation
WARNING: While wiring the meter, make sure all power is disconnected.
NOTE: Avoid exposing the LCD for prolonged periods to direct sunlight or the life of the LCD may be reduced.
NOTE: Due to many different plug types worldwide, 230-volt versions require the customer to install a
compatible male plug on the input cord side (connected to the side of the meter, goes to the electrical sup-
ply) and a female plug on the output cord side (connected to the back of the meter and will have the pump
motor connected to it). Install the plugs before installing the meter on the pump tube.
Install meter on pump tube
1. Determine which direction the flow meter display is to face. It is bi-directional and can face either to the
right or left but must be kept in the upright position.
2. Wrap Teflon tape on threads of both ends of flow meter (Item 1). Screw Hose Barb Adapter (Item 2) onto
discharge end of flow meter. Tighten securely by hand or wrench, being very careful not to over-tighten.
3. Screw 1” NPT coupling (item 3) onto the other end of the flow meter. Tighten securely by hand or
wrench, being very careful not to over-tighten.
4. Remove discharge nut, spout and o-ring (items 8, 7, 6) from PF discharge. Discard the discharge nut
and spout (or save for later use if no longer using the pump with a flow meter). Save the o-ring for use
in the next step.
5. Place the flow meter adapter (item 5) into the discharge nut (item 4) supplied with the flow meter kit.
Threads of the adapter will protrude through the front of the discharge nut. Place the o-ring (item 6)
inside the discharge nut (item 4). Press down on the o-ring to ensure it is seated in the nut.
6. Screw discharge nut/adapter/o-ring assembly onto the discharge of the PF pump tube. Use a wrench to tighten securely but do not over-
tighten. This step prevents the adapter from rotating when the flow meter is installed.
7. Remove display housing (item 9) from molded in-line body by loosening the nut. See figure 1
8. Grasping the molded in-line body (item 10), screw the flow meter assembly onto the 1” NPT discharge adapter on
the PF Series pump tube until tight.
9. Reinstall the display housing in the molded in-line body and tighten the nut. If the flow meter display is not in the
upright position proceed to step 10 for adjustment.
10. Using a wrench, loosen the discharge nut (item 4) on the discharge of the PF Series tube. Position the flow meter
assembly so the display is in the upright position and retighten the discharge nut (while holding the flow meter
assembly).
WARNING: Use chemically compatible hose rated for the temperature of the product being pumped.
11. Attach 1” ID hose to the hose barb located at the discharge end of the flow meter. Secure with a hose clamp.

Section 2 - Operation
NOTES:
• Depending on the meter purchased, the FMBC-2000 is calibrated for and displays either GPM (US gallons per minute) or LPM (liters
per minute).
• The meter is shipped from the factory with power supply transformer.
• The FMBC-2000 Series is factory calibrated to ± 1% of full-scale rate reading. Accuracy is based on laboratory testing using a PF Series
pump tube.
• Unit is factory calibrated for water. If using a fluid other than water and calibration is required proceed to section “Calibration” on page 4
before proceeding with the steps listed below.
• If flow meter is not going to be used in “Batch Control Mode” and it is desired to use it only as a rate or totalizer meter with manual motor
control (motor is turned ON/OFF by the user), plug the drum pump motor into a standard electrical supply (make sure motor is in OFF posi-
tion before plugging it in). Female plug from the meter is not used.
Theory of Operation
Start the pump motor (in Batch Control Mode the motor is started from the meter front panel). Fluid flowing through the meter causes a pad-
dlewheel to spin. Pulses generated by the spinning paddlewheel are counted and multiplied by scaling factors. The resulting flow rate amounts
and total flow amounts are displayed on the LCD readout. Pressing the enter button located on the front panel toggles the display between
flow rate and total flow or allows entry into the programming mode. Pressing the clear total button while the total flow value is displayed will
return the total to zero. A small icon will light at the bottom of the LCD indicating the mode being displayed. In Batch Control Mode the motor is
automatically shut off when the customer adjustable, predetermined set point is reached.
