5.2.2.
Testing installation
The flowcell is always hydrotested in-house at the correct hydrotest pressure before the
transducers were installed on the ultrasonic flowmeter. Herewith all welding of the flowcell is
checked. When an Ultrasonic flowmeter series 6 is installed in a pipe line, it is no longer
possible to hydrotest the pipeline. Water can be trapped between the housing and the
transducers, causing the meter to have difficulties measuring.
Before pressurizing check all pressure points on the meter. If necessary remove the cover
caps to have a clear view of the entire pressure point, particularly when an adapter is fitted
on the meter body.

Wiring instructions
All detailed information about wiring is stated the ‘Ultrasonic Flowmeter Series 6 Wiring
Instructions’ (document code 03.302.101.003.07/2), as well as Ultrasonic Flowmeter Series
6 Safety Instructions (document code 22.100.200.001.02/2). Please refer to these
documents for correct wiring of the Ultrasonic flowmeter series 6.
5.4
SPU configuration
When the meter is installed and correctly wired, it’s advisable to read out the parameter
settings of the meter. If the meter had been calibrated before, the parameter set-up should
be compared to the one of the calibration.
The parameter set-up can be read with the software package ‘SonicExplorer’. Connection
should be made through the Ethernet or DSL communication, more detailed information
about this matter can be found in the manual of the software packages. When mismatches
are detected; contact Elster NV/SA or your local representative immediately.
Warning
!
When opening the SPU (either main – or rear compartment), obey the
rules and regulations that apply to hazardous area operations.
The electronics and the main plate of the UFM should be sealed. The sealing should be
done by either the calibration facility or by Elster NV/SA. This should be done according to
chapter 4.7; any mismatch has to be reported to Elster NV/SA or your local representative
immediately.
5.5
Cold commissioning
During cold commissioning the meter is pressurized with a known gas composition, at a
known temperature and pressure, because in some cases the UFM will not be able to
measure under atmospheric conditions.
A thorough functional test is performed by means of a PC and diagnostic software package
(‘SonicExplorer’). Diagnostics and status per measuring path and the zero flow can be
checked, assuming there is sufficient pressure in the meter. A technician of Elster NV/SA
will, if this has been agreed, verify measurements and check the system performance.
