Walchem FCP-1VE PosiFlow Sensor PVC Housing with EPDM O-Rings

The PosiFlow® Sensor will verify that your metering pump is truly moving liquid into the system and has not lost prime. Utilizing proprietary circuitry coupled with advanced pressure sensing technology, the PosiFlow® Sensor provides the most accurate and non-intrusive flow verification device to date. Without any moving parts in the sensor, the standard flow path of the pump is preserved and the liquid does not move through any gears or lift a magnet to actuate a pulse in the sensor. This eliminates any concern of plugging, leaking or jamming of the flow path or sensing mechanism.The output signal of the PosiFlow® Sensor is an open-collector contact closure corresponding with each flow pulse. Additionally, a visual LED is mounted on the topside of the sensor. The LED is normally OFF, flashing green in sync with each output signal, and turns Red during abnormal pressure conditions.

The PosiFlow® will send out a signal with every stroke as long as there is liquid pumping against pressure. If the pump becomes either air-locked or in a dead head condition, the sensor will no longer output a signal. And unlike the competition, if the discharge line breaks or becomes is connected, pressure will be lost and the PosiFlow® sensor will stop signaling flow.
