4. INSTALLATION
NOTE: Numbers refer to Parts Diagram section 9.
4.1. The meter can be installed in any position, on rigid pipelines or exible
hoses, directly on pumps or tanks. The meter ow direction is xed and
indicated by an arrow on the outlet.
4.2. Meter cover (3) can be removed and the Register base (8), along with
Meter Unit (6), can be rotated at every 90° orientation in four different
positions.
NOTE: The rear of the meter body is equipped with 4 blind holes which
can be threaded (M5) for a mounting.
4.3. HOW TO ROTATE THE dISPLAY
4.3.1. Remove the four retaining screws (5) and lift up the meter cover (3), g.1.

4.3.3. Loosen the 8 screws in the sequence shown in g.3.
4.3.4. Remove the register base (8) together with the gear unit (9). Take care to NOT damage the seal (14), g.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 ret
the meter unit (6) to the new position. Make sure that the Total gears are moving smoothly.
4.3.6. Ret the meter cover (3) and x the meter label (1). Fix the Reset Knob (2) by pushing it rmly on to the reset shaft, g.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 ow stream is full and steady.
5.2.3. Stop the ow 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 ow rate into a graduated container whose capacity should not be lower than 20 litres (5 gallons).
NOTE: DO NOT reduce the ow in order to reach the preset value of the calibration container. The right method is to start and
stop the full ow 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 x 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 ow 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 ow rate will be reduced, resulting in
inaccurate measurement.
6.2.3. In eld calibration is always advisable in case of gravity installations.
7. MAINTENANcE
WARNING! Before disassembling always make sure the line pressure is released and all uid 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
insufcient ltration).

in order to remove the O ring from its seat, g.5.
7.2.3. To check the inside of the measuring chamber (13) remove the O ring (g.5).
7.2.4. Divide the two half chambers (10 and 12) containing the nutating disk (11) (g.6).
7.2.5. Use a soft brush or a small tool (i.e a screwdriver) to clean the measuring chamber. Be careful not to damage the chamber or the disk,
g.7.
7.2.6. To reassemble reverse the described procedure paying particular attention to lubricating the Seal (14) and O ring before installation,
g.8.
