Walchem’s PosiFlow® has no moving or wear parts and does not obstruct chemical feed!
The PosiFlow sensor will verify that your metering pump is truly moving liquid and has not lost prime.
The standard flow path of the pump is preserved so the liquid does not have to go through any gears or move a magnet to actuate a pulse in the sensor. This eliminates any concern of plugging or jamming of the sensing mechanism. The Posiflow Sensor utilizes proprietary circuitry coupled with advanced pressure sensing technology to provide the most accurate and non-intrusive flow verification device to date.
