Can the flow meter be installed at the pump inlet?
Thread Content
May I ask all my Haichuan friends?: Can the flow meter be installed at the pump inlet? We usually install it at the exit. However, there was a renovation project where the workload of installing the exit was too much, so we considered installing it at the entrance. But I have never seen it installed like this before. Is it okay? Are there any specific requirements? Of course, flow measurement still needs to be accurate. in addition: There is no problem of pressure drop and cavitation erosion at the inlet. Thank you in advance.
It cannot be installed at the pump inlet because of the change in pipe diameter at the inlet.
The installation of the flow meter must first meet the requirements of the flow meter itself, such as the front and rear distance and vertical or horizontal installation. You can ask your instrument engineer about this. Secondly, it depends on the measurement accuracy requirements. Furthermore, it depends on whether there are multiple lines at the outlet of your pump. If there are multiple lines, there will be problems especially when looking at the flow meter during adjustment. If these are all met, depending on your specific situation, I think it may not be impossible to put it into the mouth.
Furthermore, you should note that you also need to check whether the pump's cavitation meets the requirements.
Do you want to measure the export flow rate? ? If the pipe diameter is converted into outlet flow, it can also be installed at the inlet, but the installation conditions of the flow meter must be ensured: D
I think it should be possible, but it needs to meet the installation requirements of the flow meter.
As long as it does not affect the suction conditions of the pump, it can be installed at a pump with a low inlet pressure level and is cheap.
It should be treated differently according to the specific situation. For example, the distillation tower kettle pump transports liquid that is close to saturation. If a flow meter is installed at the pump inlet, it will easily cause cavitation of the pump. In the absence of cavitation, as long as the pipe length is sufficient, there seems to be nothing wrong with it. This post was last edited by tianshanxue on 2007-12-17 08:42 ]
As long as it meets the needs of the flow meter, it can be installed at the entrance. If combined with the ones on the 3rd, 7th, and 8th floors, it will be comprehensive.
