5.2 - Calibration Procedure
Calibration procedure for mechanical TECH-FLOW,MAT-FLOW, R-FLOW meters:
Fill the container up to a measured quantity.
If the amount displayed does not match the measured quantity, the meter must be calibrated. Make sure
the pump is off and the system is not under pressure before moving onto the next point.
Remove the sealing plug and turn the calibration screw anticlockwise to
reduce the quantity displayed or clockwise to increase it (a full turn
changes the quantity displayed by about 2 litres).
Put the sealing plug back.
Repeat the previous points until calibration is acceptable.
CAUTION: if the amount of liquid dispensed is less than 5 litres, the device will not allow
calibration.
PROBLEMS: POSSIBLE CAUSES:
SOLUTIONS:
The meter does
not read
Suction filter clogged
Clean the filter
Meter placed incorrectly
Check the direction arrow of the liquid on the body; if the meter has been installed
upside down it won’t work
Incorrect reading
precision
Flow rate too low or too high
check the technical specifications for the flow rate limits (Chap. 12.2)
Incorrect calibration
Follow the procedure for a new calibration (Chap. 6.2)
Air inside the system
Check for any air intake leaks and make sure the pump does not draw in air

7 - MAINTENANCE
7.1 - Cleaning
TECH-FLOW, MAT-FLOW, R-FLOW meters do not have a suction filter. It is advisable to add a suction
filter of at least 40 mesh to prevent any residues from interfering with the mechanical parts measuring the
fluid. To clean the filter, see the instruction manual provided with the filter used.
If the meter is to be scrapped, its parts are to be given to companies specialised in disposing of and
recycling industrial waste, as shown on the table below:

PACKAGING
The packaging consists of biodegradable cardboard which can be sent to companies for normal pulp recycling.
METAL PARTS
The metal parts, whether painted or aluminium and stainless steel, are usually recycled by companies specialised in the scrap
metal industry.
PARTS OF A DIFFERENT NATURE
Other parts of the system in which the meter is installed, such as pipes, rubber gaskets, plastic parts and wiring, are to be given to
companies specialised in disposing of industrial waste.
