Flow meter selection
Thread Content
It’s a small-scale testing setup, and a rotameter has been chosen for use; however, it keeps getting stuck during operation, which is really troublesome. Does anyone have any good suggestions?
Consider replacing it with an electromagnetic flowmeter or an ultrasonic flowmeter; these two types of flowmeters have no moving parts, thus avoiding jamming issues. At the same time, they are also suitable for various types of liquids, and their maintenance is relatively simple. If changing the type is not feasible, please check whether the installation location of the rotameter and the pipes are appropriate, as well as to perform regular cleaning and maintenance. .
Try adding a spring damper at the top.
Some dampers have this issue: when trying to adjust the flow rate, they either can’t go up or down, remain unchanged, or fluctuate wildly
Thank you very much:handshake
You need to specify the medium, flow rate, dimensions, as well as temperature and pressure conditions. Typically, pilot-scale devices use rotors. Check if the selection is correct. Electromagnetic and ultrasonic methods are probably not needed; for gases, a rotary element can be used, while for liquids, a turbine based on volume can be employed.
Methanol, flow rate of 25 L/h, DN10, 30°C, 30 KPa
The range was not selected properly; the usual flow rate should be set at an appropriate level
There’s no problem with choosing this rotor; pay attention to the pressure difference and flow rate before and after. Choose well, as mentioned downstairs.
