SONIX 30D
ERRORS
13
Service of the flowmeter is performed only by the SONIX servicing team.
Service includes:
– supervision over the assembly and start-up of the flowmeter
– dignostic and measurement error analysis of existing installations
– repair of flowmeter electronic
– relacement and adjustment of the ultrasonic probes
– „wet” calibration for flowmeters DN≤300
– theoretical calibration acc. to PN/M- 42370 for flowmeters DN>200
Servicing
General
information
The last 2 digits displayed on the top line on the dignostic screen E2 should
be the same. It means that desired and current mode of work are the same.
In the case of work on 3-paths this digits are 77.
In the case the digits are not equal the failure is possible. For example digits
71 mean that the desired mode is working on 3 paths but flowmeter works on
AB path only.
In verified flowmeter checksums L and CRC shown on E5 screen should be
the same. Furthermore checksum L is printed on meters label.
When the checksums are not equal pulse output is blocked and the meter
signals inconsistency.
Diagnostic
messages
Na ekranach E2 i E3 wyświetlane są następujące komunikaty:
„measurement OK” – flowmeter measures with no errors
„adjustment” – amlification is beeing adjusted
„disturbances AB, CD or EF” – more than 50% are disturbed
„low signal AB, CD or EF” – a decrease of the signals from the pair of
probes
„inconsistency” – current and programmed mode of work are different or
checksums are not equal for a verificated flowmeter
“measurement OK” - the measurements are done correctly.
