Flow transmitter
FCP series
Walchem
We've written new software into the WebMaster to make the PosiFlow® an integral part of your system. The PosiFlow® sensor is installed on the discharge side of the metering pump, and connected to the digital input option card of the WebMaster. The sensor supplies a contact closure to the WebMaster every time the metering pump pulses and the sensor detects fluid movement. The controller is programmed to know which relay the pump is connected to, and how long to wait after activating the relay before expecting a pulse from the PosiFlow® sensor. The controller will send an alarm if the pump should be operating but no flow pulses are received. The controller can also use a programmable volume-per-stroke value to totalize the volume of chemical fed.
