3.4 Commissioning
All electrical supply, operating and measuring lines and the pressure connec-
tions must have been correctly installed before commissioning. All supply lines
are arranged so that there are no mechanical forces acting on the device.
• If liquid measuring media are used the pressure connection lines must be
vented, as liquid columns of different heights in the pipes can cause meas-
uring errors. The instrument must be protected against frost, if water is used
as a measuring medium.
• Appropriate shutoff valves must be provided to ensure safety during installa-
tion, maintenance and inspection
