gas flow measurement
A stable zero is mandatory for a good mass flow measurement. Mechanical installation stress and flow
noise influence zero stability. Action has to be taken to avoid any generation of sound.
Recommendations:
• Support the weight of the detector by soft coupling (silicon or other kind of rubber support.
• Do not bend or stress the detector via the adjacent pipe. This is achieved by supporting the pipe 10D or
more away from the detector.
• Pipe reduction or extension should be avoided directly before or after the meter.
• Avoid any control valves or orifices or any other sound generator near the detector.
