Selection of chemical process flowmeters
Thread Content
For equipment materials transported via negative-pressure pipelines, what type of flow meter is the best choice?
Consider the nature of the material: solid, liquid, gas?
It has to be a gas; choose one with low pressure loss – the lower, the better.
Can a flow meter really be selected with the conditions given by the original poster? You need to provide sufficient details (such as the medium, flow range, operating pressure, etc.), because there are many types of flow meters, and each type has its own applicable range; only by providing enough information can the right choice be made.
Ask seriously, and choose seriously; asking like this, vortex street it is: lol
This question is too general; the selection of a flow meter depends entirely on the properties of the fluid and the user’s requirements regarding measurement accuracy. Additionally, it is necessary to choose a flow meter that offers good cost-performance while still meeting those requirements, and there are many options available.
Materials? Pumping? Is it high in viscosity and slow in flow rate? Differential pressure type flow meters; perhaps a wedge flow meter would work
By negative pressure, do I understand it as the pump drawing fluid from downstream? If that is the case, it is recommended to use flow meters with caution, as negative pressure may cause vacuum effects, and this can generally affect flow meters. As for negative pressure caused by other reasons, I won’t explain it since I don’t understand it.
