Pump Calibration Columns

Chemical metering pump Calibration Columns and Calibration Cylinders provide a fast, easy and economical method for determining pump flow rate using standard graduations of milliliters/minute (ml/min) and gallons/hour (gph). The calibration cylinders / columns offer accurate testing of metering pump flow rate by measuring the draw down rate on the suction side, while leaving the discharge undisturbed in its normal steady state operation condition.
