4.3.3.
Loosen the 8 screws in the sequence shown in fig.3.
4.3.4.
Remove the register base (8) together with the gear unit (9). Take care to NOT damage the seal (14), fig.4.
4.3.5.
Rotate the register base (8) to the desired position. The display can be placed in the 4 positions. Tighten the base screws (7) and refit
the meter unit (6) to the new position. Make sure that the Total gears are moving smoothly.
4.3.6.
Refit the meter cover (3) and fix the meter label (1). Fix the Reset Knob (2) by pushing it firmly on to the reset shaft, fig.1.
5. cALIbRATION
5.1.
The meter is pre-calibrated in the factory under standard conditions. A new calibration is necessary whenever:
- the meter is disassembled for maintenance
- the media used is different from diesel oil.
5.2.
cALIbRATION
5.2.1.
Remove the plug and seal (17).
5.2.2.
Vent the air from pump, pipelines and meter by dispensing until the flow stream is full and steady.
5.2.3.
Stop the flow by shutting off the nozzle, but let the pump run.
5.2.4.
Reset the batch total using reset knob (2).
5.2.5.
Dispense at the desired flow rate into a graduated container whose capacity should not be lower than 20 litres (5 gallons).
NOTE: DO NOT reduce the flow in order to reach the preset value of the calibration container. The right method is to start and
stop the full flow repeatedly until the required level is maintained.
5.2.6.
The Meter Value should be matched with the Container Value as given below:
- If the Meter Value is higher than Container Value, loosen the calibration screw (16).
- If the Meter Value is lower than the Container Value, tighten the calibration screw (16).
5.2.7.
Repeat steps until accuracy is satisfactory.
5.2.8.
Tighten the plug with seal (17) again.
NOTE: Always fix the plug with seal (17) to avoid leakage because the O ring on the calibration screw (16) does not have any sealing
function. (The O ring in this case only avoids accidental loosening of calibration screw).
6. OPERATION
6.1.
After installation, turn the rest knob (2) until the batch total is completely reset. The totaliser can not be reset in any way.
6.2.
USE bY GRAVITY
6.2.1.
The meter can be used without pump pressure in a system where flow is generated due to difference in height between fuel level and
dispensing point.
6.2.2.
Use by gravity is not recommended where the height of the fuel is lower than 4 feet as the flow rate will be reduced, resulting in
inaccurate measurement.
6.2.3.
In field calibration is always advisable in case of gravity installations.
7. MAINTENANcE
WARNING! Before disassembling always make sure the line pressure is released and all fluid is drained from the meter.
‰
7.1.
The meter does not require any special maintenance other than cleaning of the measuring chamber, (it may get clogged due to
insufficient filtration).
