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.
4.3.2. Loosen the 2 screws, see g.2, on both sides and separate the meter unit (6) from the register base (8).

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 ret
the meter unit (6) to the new position. Make sure that the Total gears are moving smoothly.
4.3.6. Ret 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
insufcient ltration).

NOTE: The meter can be easily disassembled into its main parts without removing the body from the pipes:
- Never remove meter label from the meter.
- Cleaning is done with a soft brush or small tool (i.e. a screwdriver).
- During cleaning, be careful not to damage the measuring chamber or nutating disk.
- A new calibration is always necessary after disassembling the measuring chamber.
7.2. CLEANING OF THE MEASURING CHAMBER
7.2.1. Remove the knob (2) by pulling it axially outwards. Remove Meter cover, Meter unit and Register base by following steps 4.3.1 to 4.3.4
from the section 4.3 ‘How to rotate the display’.
7.2.2. Remove the whole measuring chamber (13) by lifting it from the lower body (15) and at the same time pulling it back towards the inlet
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.
7.2.7. Check the gear unit (9) can rotate freely before xing the cover, g.9.
7.2.8. Recalibrate the meter as mentioned in section 5 Calibration.
