Pump selection for high gas content & installing a flow meter at the diaphragm pump outlet: could this lead to inaccurate measurements?
Thread Content
As indicated in the title, a stream of material needs to be transported; the flow rate is low at 100 L/h, the operating pressure is high at 3 MPa, and the gas content in the material is 15%, which makes it difficult to find a suitable centrifugal pump. I am planning to use a diaphragm pump, but I’m not sure whether it will fail to deliver liquid during operation due to high air content. I would appreciate some guidance from you all. Also, if a positive-displacement pump (diaphragm pump, metering pump) is used, can a flow meter be installed on the pump outlet pipeline? Since the pump delivers fluid in pulses, will the flow meter give inaccurate readings?
Your last few questions remind me of a component I found at the outlet of a diaphragm pump back then; what do you think? ;P Milton Roy pump outlet components? https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1186035&shareuid=398787
