CALIBRATION OF A METERING PUMP
To perform a calibration test on the delivery rate you will require a stop watch and
materials necessary to perform a series of simple calculations.
To utilise this system efficiently, the following procedure should be followed whilst the
pump is operating.
1.
Valve V1 must remain open except when the user is testing the deliver
rate.
2.
To test the delivery rate, open valve V2 and flood the calibration
cylinder well above the top graduation mark.
3.
Close valve V1.
4.
At the moment when the fluid level reaches the top graduation mark,
begin timing the test.
5.
When the liquid reaches the desired lower graduation, stop your watch
and note down the time and calibration discharge quantity. Open valve
V1 quickly and close V2 to avoid air being drawn into the system via the
calibration cylinder.
6.
Should another calibration test be required, then proceed to Item 2.
