At a minimum check below, that system pipe A.H. + pipe friction + lack of "overlap" from system liquid compressibility; is not producing greater system pressure pulsation than allowed, to prevent pipe shake fatigue fracture (per API 674 etc).

prevent pipe shake fatigue fracture

When your system pipe and fittings plus liquid cP, SG and compressibility pulsation, has been checked against the above nomogram - please review the other necessary pressure smoothness and frequency criteria for your instruments, meters, etc.

 
Frequency of the pulsation, f, how many peaks (and valleys) per second called Hertz “Hz” Beware some specifications refer to “peak to peak”. As time is normally the horizontal axis, this could mean time lapse or Hz. Internal diameter of pipe in inches Maximum allowable peak to valley pressure variation PSI
