Blue-White FLEX-PRO A2 ProSeries Peristaltic Pump - Manual (Page 15)

Page 15 Flex-Pro
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.
