“Gear“ flowmeter
Standard
For “Gear” flowmeters, if a measurement cell is not used for a long
period, it must be washed with a suitable solvent. The washing is
particularly important for measuring instruments, since the
products release particles that can stick to the gear wheels. For
disassembly, follow the manufacturer's instructions (see Chapter
11 documents)
The accuracy of the measuring cell must be checked at regular
intervals by means of calibration. After about 8000 hours of activity,
the calibration must be controlled by the manufacturer.
The activity of the “gear” flowmeter is controlled by the PLC, and if
the number of switching operations carried out exceeds the
programmed value, the display shows the following message:
"MAXIMUM NUMBER OF PULSES ACHIEVED, PROVIDE
MAINTENANCE".
When the message appears, you must replace
the flowmeter as soon as possible
On flowmeters with optical fiber there is a battery.
The battery must be replaced every year to
ensure the correct operation of the machine.
With fibre optic
“GEAR FILTER” (only for versions with gear Flowmeter)
Daily remove the filter, clean the cartridge or replace if necessary.
For the model, see drawing mixing panel attached to this manual.
