We provide calibration columns for suitable for a wide variety of chemical pumps and chemical feed systems.

 

These calibration columns provide a reliable and affordable means of verifying
the flow rate of your chemical metering pump.

The most accurate test of metering pump flow rate is to measure the drawdown rate on the suction side while leaving the discharge undisturbed in its normal steady state operating condition. Pump flow rate verification on a periodic basis or after maintenance is important to system accuracy. The Calibration Column can also be used to determine if check valves are worn or dirty. It is recommended to size the Calibration Column for a minimum of 30 seconds with a scale that will produce an easily readable differential within the test period. Features
