Koflo Pump Calibration Columns are an easy to use method for determining pump flow rate 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.
Typical installation of calibration column between pump and tank assembly
|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.|
