Which flow meter can be used as a substitute for weight-based measurement? https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1300954&shareuid=4554153
In the process of metering liquid materials, if weighing cannot be used, the following flow meters can be considered as alternatives: 1. Electromagnetic flow meters: Suitable for liquid media, they measure flow rate by detecting the electromagnetic induction that occurs when liquid flows through a pipe. They offer advantages such as high accuracy and good stability. 2. Ultrasonic flow meter: It measures the flow rate of liquids using ultrasonic sensors, enabling non-contact measurement; it is suitable for various liquid media as well as large-diameter pipes. 3. Turbine flow meter: It measures flow rate by utilizing the fact that the frequency of vortices generated by fluid flow is proportional to the flow velocity; it is suitable for liquid media with low, medium, and high viscosities. 4. Angle-measuring flow meter: Calculates flow rate by measuring the rotation angle or speed of the rotor, and is suitable for liquid media with low flow rates. Selecting the appropriate flow meter requires comprehensive consideration of factors such as the specific application scenario, properties of the liquid, flow range, and accuracy requirements. It is recommended to consult a professional flow meter supplier or engineer before making a selection, for a detailed evaluation and confirmation. .
Mass flow meters, I deal in instrumentation; we can discuss this if there is any interest. I’ve also created a group for exchanging ideas on chemical process instrumentation; those who are interested in joining can add me on WeChat at gyqtbs008
A mass flow meter can be used, but it’s a bit expensive. If the density remains constant, it is also possible to use an electromagnetic flowmeter or similar device to measure the volume flow rate and then convert it.
Mass flow meter, but its accuracy is definitely not as high as that of a weighing device
I’ve learned something new, thank you for sharing
A gear rotor flowmeter operates like a measuring process done scoop by scoop; however, a filter must be installed. The presence of impurities can affect the operation of the rotor.
