Mitigating the Effects of Pulsating Flow in Flow Measurement
Titan Enterprises has published a new technical article that 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 which can generate errors in flow measurement. Pulsating flows are common in systems using diaphragm, peristaltic or piston pumps for example. 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.
Using advanced electronics, Titan's Atrato® and Metraflow® ranges of ultrasonic flowmeters are able to resolve the ultrasonic signals to about 50 picoseconds. With downstream signal processing, Titan’s ultrasonic flowmeters are able to accurately measure pulsating fluid flow that is less than 10Hz. To accurately measure pulsating flows above this frequency requires inline pulse dampening.

About us
With over 40-years experience in flow meter innovation, Titan Enterprises Ltd are a UK-based manufacturer of high performance solutions such as the Atrato ultrasonic flowmeter, Oval Gear flow meters and the low flow Turbine flow meters and instrument range.
Our knowledgeable team can offer either an off-the-shelf meter or fully bespoke flow system designed for a particular application whether it is a low cost OEM solution or a specialist flowmeter in exotic materials. Titan supplies innovative flow measurement solutions into a broad range of sectors, including medical, industrial, food and drink, laboratory and pharmaceutical, offshire oil & gas industry, power, chemicals and mining.
For higher volume users we can custom design a flowmeter to match exact application requirements and thus not compromise achievable results with a less than ideal sensor.
At Titan we endeavour to produce devices that are inherently reliable as well as manufactured using the latest and most economical production technology. All flow meters produced by Titan are designed and manufactured to ISO9001 and calibrated to an uncertainty of ±0.25%.
We produce chemically resistant, high accuracy digital flow meters that are not only competitively priced but are engineered to give long-term reliable performance.
