4.6.2 Vortex and Swirl flowmeters
If the medium is conveyed through piston/plunger pumps or compressors (pressures for fluids
> 10 bar (145 psi)), it may be subject to hydraulic vibration in the pipeline when the valve is
closed. If this does occur, the valve absolutely has to be installed in the flow direction upstream
of the flowmeter. Suitable dampers (e. g. air vessels in the case of pumping using a
compressor) might need to be used.
