Flow Verification Sensor is designed to give you two installation options.
Sensor can be installed:
!
Directly on pumphead of A2 pump, suction side.
!
Anywhere on suction side of A2 pump.
Wiring for sensor can be connected directly to an A2 pump. Pump will stop pumping if sensor detects no flow. A
relay will then close allowing for remote alarm indication or initiation of a back-up injector pump.
Install FVS Flow
Sensor -
Flow Verification Sensor should be installed on inlet (suction) side of pump tube. Sensor includes a PVC
tubing insert, located inside sensors female thread connection, that is designed to seal sensor onto pump tube
inlet adapter. Thread sensor onto pump tube until tubing insert is snug against pump tube inlet fitting - do not
over-tighten.

Confirm FVS flow range -
Flow Verification Sensor (FVS) will only function
within its operating range. See chart for available ranges.
Example: Sensor model FV-100 has an operation range of 30-300 ml/min
when used as a flowmeter. However, due to pressure drop across sensor,
pump’s suction capability is limited to 14.7 psi. When used as a Flow
Verification Sensor with a peristaltic pump, effective operating range is
reduced to 30-200 ml/min.
NOTE: If pump output is less than 30 ml/min, sensor will not detect chemical
and a signal will not be sent to pump, resulting in an alarm condition.
NOTE: For low viscosity (water-like) fluids only. Consult factory if attempting
to use with viscous fluids.
Flow verification sensor sold separately.
Flow verification system is designed to stop pump in an event sensor does not detect flow during pump operation.
Indicating an empty chemical tank, clogged injection fitting, loose tubing connection, etc.
To allow pump to clear any gasses that may have accumulated over time, an alarm delay time value from 1 to 255
seconds must be programmed.
Note: An alarm delay of 000 seconds disables FVS system.
Step 1
Press and release STOP button
Note: Mode cannot be changed while pump is in running.
Press and release SELECT RUN MODE button multiple
times until Mode 0 is selected.
Step 2
With Mode 0 selected, press and hold SELECT RUN MODE
button until ‘Remote’ icon begins flashing.
This indicates that you’ve entered Setup menu.
Step 3
Press and release RIGHT arrow to scroll through menu until
you see FVS icon.
If you pass FVS screen, continue to press and release
RIGHT arrow button until FVS icon appears.
Step 4
FVS icon will appear for 1 second, followed by numbers.
These numbers indicate delay time setting for FVS.
Select a delay time in seconds. Delay time is amount of time
pump will wait to receive a pulse from sensor until an alarm
it triggered.
A delay time of 00 deactivates FVS feature.

Time-out
- Flex-Pro pumps have a time-out setting of 20 seconds while in configuration menus. If built-in timer exceeds 20 seconds
without a button being pressed, then pump will exit configuration menu. Changes will only be saved after RIGHT arrow button is
pressed and released.
