Meter Calibration
All consumer electric pumps are adjusted for accurate measure within
±
.05 units at the factory
for the fuel specified on the order. However, since the conditions of the installation can affect
pump accuracy, it is the responsibility of the installer to check the pump for accuracy and
make any needed adjustments. Where required, it is the owner’s responsibility to report this
device to the local Weights and Measures officials for their inspection before the unit is put
into service.
Choose the flow rate at which the meter will be used most often for the zero calibration point.
Use a certified measure with a sight glass and scale.
To calibrate the meter, proceed as follows:
1 Fill and drain the test measure to completely wet the interior surfaces.
2 Reset the register to zero and deliver an exact measured quantity into the test measure at the
selected flow.
3 Read the level of the liquid in the sight glass on the scale.
4 Count the number of full turns and fractional turns each time for reference in judging the
number and direction of any additional turns required to calibrate the meter to exactly zero.
