Calibration Columns
Purpose
Neptune Calibration Columns provide a
fast, easy and economical means of checking
the flow rate of your chemical metering pump.
The most accurate test of metering pump flow rate
is to measure the drawdown rate on the suction side
while leaving the discharge undisturbed in its normal
steady state operating condition. Pump flow rate
verification on a periodic basis or after maintenance
is important to system accuracy.
The Calibration Column can also be used to determine
if check valves are worn or dirty.
It is recommended to size the Calibration Column for a
minimum of 30 seconds with a scale that will produce
an easily readable differential within the test period.
Features
• Rugged PVC construction with slip on top
caps for top filling and easy cleaning
• Shielded glass models available for acids
and strong chemicals
• Calibration scales are protected from harsh
chemical by Mylar lamination
