Koflo 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.

How to use a calibration column:

1.

Install pump calibration columns on the suction side of pump as shown on the drawing.

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 secondhand.

4.

At the one-minute mark, observe the fluid level. This is 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.
