Pump Calibration Columns

Pump Drawdown Calibration Columns and Calibration Cylinders

Our Koflo 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. High contrast blue lettering enhances readability in all light conditions, and all scales have a protective Mylar lamination to protect against chemical attack. All sizes feature rugged construction using industrial grade machined PVC fittings.

100 ML CC

Koflo 0-1.5 GPH Pump Calibration Column (Calibration Cylinder)
Flow Range (gph): 0 - 1.5 gph (0.02 scale divisions).
Flow Range (ml/min): 0 - 100 ml/min (1.0 scale divsions).
Calibrated to display ml/min and gph after a 60 second drawdown at the suction side of the pump.
Pump Calibration Columns / Calibration Cylinders are an easy to use method for determining pump flow rate using industry standard graduations of milliliters per minute and gallons per hour. An equal starting point for both graduated scales gives the operator both ml/min. and GPH in one test.
