Combating Errors Induced By Pulsating Flow in Flowmeter Measurement Flowmeters are well known to be sensitive to effects like pulsating flow, which can cause 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.  Figure 1.

Therefore, the key source of potential error in electronically sampling flow meters, like ultrasonic devices, is the sampling rate and how it will sense the real flow that passes through it. Ho...
