New calibration columns provide a fast, easy and economical means of checking the flow rate of a chemical metering pump. The columns offer accurate testing of metering pump flow rate by measuring the drawdown rate on the suction side, while leaving the discharge undisturbed in its normal steady state operation condition. The calibration column can also be used to determine if check valves are worn or dirty. System accuracy is ensured by verifying pump flow rate on a periodic basis or after maintenance.
