Set FVS (Flow Verification System)
Used to monitor pump output. If pump does not dispense fluid when pump
head rotor is turning, pump will go into an alarm mode and stop pump. Blue-
White offers a flow verification sensor that can easily attach to fitting on pump.
Default settings:
000 (off)
Navigate to Set FVS menu by pressing MENU button, then selecting Input
Setup, and then Set FVS.
Press UP or DOWN arrow to scroll through 0 - 9 on selected digit.
Press RIGHT arrow to scroll over to next digit to right. If you pass your desired
digit, you can easily scroll back by continuously pressing RIGHT button.
Press ENTER to save changes and exit FVS screen.
To navigate back out of menus, select <-Esc and press ENTER button at
bottom of every screen menu until you see Run Mode screen displayed.
Flow Verification System (sensor sold separately)
A3 is equipped with a Flow Verification System which is designed to stop pump
and provide a contact closure output or 10 amp relay output (setup in software)
in event sensor does not detect chemical during pump operation. This could
indicate a clogged injection fitting, empty chemical solution tank, worn pump
tube, loose tubing connection, etc.
To allow pump to clear any gasses that may have accumulated during stopper
operation (such as with chlorine), an alarm delay time value from 1-255
seconds must be programmed (An alarm delay value of 000 seconds disables
FVS system).
If FVS alarm occurs, pump will stop, send an external signal (if setup), and
screen will flash FVS with an alarm icon.
To clear FVS alarm, you must press START button or re-cycle power (unplug
power to pump, then plug back in).
Install FVS Flow Sensor - Flow Verification Sensor (FVS) should be installed
on the inlet (suction) side of the 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 the FVS flow range - Flow Verification Sensor (FVS) will only
function within its operating range. Sensor model FV-100 has an operating
range of 30-300 ml/min (1-10 oz/min) when used as a flowmeter. However, due
to pressure drop across the sensor, the pump’s suction capability is limited to
14.7 psi. Therefore, when used with the peristaltic pump as a flow verification
sensor, the effective operating range is reduced to 30-200 ml/min. Note that if
the pump’s output is less than 30 ml/min, the sensor will not detect chemical
and a signal will not be sent to pump.
