General information

UR 300/UR 400 is mechanical flow meter with oscilating disk, designed to allow a precise
measurement of Diesel oil or other fluids compatible with the manufacturintg material. The
nutating disk of the metering chamber (see exploded view, kit n°1), which is set in motion by
the fluid itself, drives the gear train located in the cover of the meter body (n°7) which transmits
the motion to the meter (n°9). The meter is equipped with a nonresettable litre totaliser and
a batch register which can be reset by means of a knob (n°10), whose unit digit is provided
with marks for the readout of the tenths of a litre.

Calibration
UR 300/UR 400 is pre-calibrated in factory to be used with Diesel oil. As specific operating
conditions (such as real flow rate, nature and temperature of the measured fluid) may affect
the meter accuracy, a re-calibration should be carried out after the installation has been
completed.
A new calibration is necessary each time the meter is disassembled for maintenance operations
or when it is used to measure fluids that differ from Diesel.

Calibration procedure

1. Purge the system (pump, pipelines, meter) of air by dispensing until the flow stream is
full and steady.
2. Stop the flow by shutting off the nozzle, but let the pump running.
3. Reset the batch register by means of the reset knob (n°10)
4. Dispense at the flow rate which the best accuracy is required at by using a calibration
container haing a capacity not lower than 20 liters. Do not reduce the flow in order to reach
the graduated zone of the calibration container. The right method is to start and stop the full
flow repeatedly until the required filling is obtained.
5. Compare the indication of the calibration container (real value) with the one of the meter
(indicated value).
- If the indicated value is higher than the real value, loosen the screw (n°3)
- If the indicated value is lower than the real value, tighten the screw (n°3)
6. Repeat the operations 4 to 6 until accuracy is satisfactory.

To ensure a proper and safe use of the meter it is necessary to
read and follow the instructions and warnings contained in this
manual.
An improper installation or use of the meter may cause
damage to objects and people.
