Start-up
5.1 Standard device
A minimum operating pressure (primary pressure) is necessary to operate the device:
CAUTION!
When starting up the device, the following points must be observed:
• Compare the actual operating pressure and the product temperature of the system with the
specifications on the nameplate (PS and TS). These specifications may not be exceeded.
• Make sure materials are compatible.
• Slowly open the shut-off valve.
• When measuring liquids, vent the pipes carefully.
• When measuring gases, increase pressure slowly.
• Avoid float impact (e.g. caused by solenoid valves), as this is likely to damage the measuring
unit or float.
Medium Pressure loss : operating pressure
Liquids 1 : 2
Gases without float damping 1 : 5
Gases with float damping 1 : 2
