Pulsation Measurement

Correctly measuring pulsation is more difficult than it seems. As mentioned elsewhere (Link), Pressure = LinePressure + Kinetic Pressure + Pulsation. Line Pressure (LP) usually is measured without much problem. LP can be affected by Pulsation when long tubing leads to the pressure sensor (see Figure 1). Industry-type pressure sensors tend to be placed on a small bore fitting, often with a blocking valve situated between the pressure sensor and the flange (see Figure 1- flange not shown). This setup works for Line Pressure and suppresses Kinetic Pressure, but is less ideal for pulsation...
