6.1.3 TESTING THE DISPENSER
The following procedures must be performed at each nozzle position:-
• Test the flow rates (litres/minute) - refer to the WWC Calculator Manual for
more detailed information.
Note : Flow rates will vary depending on site conditions, and should be
adjusted accordingly using the pump bypass.
For VR nozzles, set the flow rate between 36 and 40 LPM.
• Test the meters are within the legal requirements:-
- Lift each nozzle and deliver approximately 20 litres into a Tokheim
approved calibrated container until all air and fuel substitute has been expelled
through the nozzle and/or air vent pipes.
Note : Discard this filling since it will contain fuel substitute from the
dispenser pipes and components and air from the supply pipes.
IMPORTANT : DISCARD ALL TEST FILLINGS SAFELY.
• Perform a test filling into the calibrated container until 20 litres have been
dispensed according to the calculator display.
• Read the measurement on the calibrated container.
If the fuel dispensed into the container is above or below the calibration line
(i.e. greater or less than the 20 litres dispensed) then the meter must be adjusted
to ensure Weights & Measures (W&M) compliance.
Note : W&M regulations vary according to different countries.
6.2 Calibration of the Dispenser
If the meter is fitted with an enhanced pulser for electronic calibration (MPE-EC) or
temperature compensation (MPE-TC) then it should not be necessary to perform mechanical
calibration. Refer to section 6.2.2 to perform electronic calibration.
MID CERTIFIED DISPENSERS
MID certified dispensers are calibrated in the factory with the relevant seals stamped so it
can be put into operation immediately upon installation without Weights & Measures
verification. Refer to section 1.7 for the identification of MID dispensers.
If requested by the site owner, a calibration check could be performed as part of the
commissioning procedure.
If the calibration is outwith legal tolerances, the factory MID verification would be
invalidated. The meter should be adjusted by the commissioning engineer (under factory
approval) before the dispenser becomes operational.
