How to Mitigate the Effects of Pulsating Flow

A new technical article from Titan Enterprises discusses how variation in flow velocity can impact flow measurement accuracy and how to mitigate any undesirable effects. It is well known that flowmeters are sensitive to effects such as pulsating flow in systems using diaphragm, peristaltic or piston pumps which can generate errors in flow measurement.

In a pulsating flow system, the velocity profile of the flow undergoes a dramatic change during each cycle of pulsation compared to even flow conditions. According to theory, to accurately measure flow in a pulsating flow scenario the sampling rate of an electronic flow meter needs to be at least double the frequency rate of the pulsations themselves. If the pulsation rate is not taken into account, aliasing of the flow signal will be seen, resulting in erroneous measurement from the flowmeter.
