Metering Pump features automatic discharge volume control.
Fluid & Gas Flow Equipment

Metering Pump features automatic discharge volume control.

PZiA Electronic Metering Pump utilizes circuitry that allows for on-board calibration of pump flow under actual process conditions. Once calibrated, pump can be set to flow rate, or analog signal can define flow rate. Pump will automatically adjust to maintain precise flow rate, compensating for changes in temperature, pressure, or viscosity. Flow Checker transmits actual flow data to pump...
