With the pump installed under normal operating conditions, place the
suction tubing in a graduated container.
Fill the container with the same chemical normally injected, and run the
pump until all air is removed. (Prime the pump).
Refill the container if necessary, and with the foot valve in the solution,
note the amount of chemical in the container.
Using a stopwatch or timer, run the pump for a measured amount of time
(example: 1 minute). Note the amount of chemical pumped during that time.
Tip: The longer the
testing time, the more accurate the measurement.
Example:
During your 1 minute calibration period, say
your injector pumped 2.5 ounces.
2.5 ounces per minute (OZM)
Your pump is calibrated to pump 1.17 GPH - or - 28.08 GPD

Caution:
Always wear protective clothing, face shield, safety glasses and gloves when working on or near your metering pump. Additional precautions should be taken depending on the solution being pumped. Refer to MSDS precautions from your solution supplier.
