Operation Instructions – High Pressure Gas Meters (Chapter 4)
4. High-Pressure Gas Meters(> 1bar)
The Gas Meters may only be used within the Over-Pressure and Temperature operating limits listed on the Meter label and in the Data Sheet.
If the Gas Meter is placed in an elevated position, for example on a stand or similar, it must be firmly secured so that it cannot move or slip. This is to avoid personal injury or property damage due to the Meter falling. The feet of the Meter should be secured with tension clamps, screws or similar.
The Gas Meters do not have an Over-Pressure Safety Valve installed. In order to completely avoid exceeding the admissible operating pressure (listed on the Meter label and in the Data Sheet), an Over-Pressure Safety Valve must be installed in the connected gas pipes.
In the event of Gas Meter disassembly, the Gas Meter must be pressure-free before disassembly begins.
Only original parts should be used to rebuild the Gas Meter if it has been disassembled.
Disassembly of the Meter, i.e. removal & replacement of the measuring drum, can alter the calibration results (please refer to Point 5.2).
