Before analyzing system pressure amplitude at frequency and causes, determine acceptable maximums. Below are suggestions.

Percentages are of theoretical steady state condition.

 

60% shaft deflection Spray blobs have atomization , 5% Constant streams in fully mixed out First in first out bad static mixing without continuous flow, 3.5% to 4% Bobbin in tapered transparent tube, 4% 6% set frquency pulsed magnetic field "Mag Meter" 3.0% paddle wheel meter Turbine meter, 1.5% Coriolis vibrating tubes meter, 1% “Delta P” orifice meter, 1 psi max Vortex shedding, .75% Spinnerette heads. 0.1% DQ Denier checked by laser beam precisely Film thickness control, 0.2% Web coating
