Calibration Columns

Koflo Pump Calibration Columns are an easy to use method for determining pump flowrate using industry standard graduations of milliliters/minute and gallons/hour. An equal starting point for both graduated scales gives the operator both ml/min. and GPH in one test. 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 PVC fittings.

Pump Calibration Columns Instructions

Operating Instructions
1.	Install calibration column on the suction side of pump.
2.	With valve A open and the pump operating, open valve B slowly until fluid level reaches the 0 mark.
3.	Close valve A and begin timing with a stopwatch or wristwatch second hand.
4.	At the one minute mark, observe fluid level. The observed level indicates the actual pump flowrate in mL/min and GPH.
5.	When not in use, the calibration column should be drained, valve B closed and valve A opened.
