Seeking advice on metering pump issues
Thread Content
Quiet, no such thing as ETYE LV.0 1# Edit: Only view the original poster’s post. 0 20 1 hour ago. I recently bought a metering pump for testing purposes; after connecting the pipes, I installed a turbine flow meter on the outlet pipe. However, the flow rate measured showed significant fluctuations, with the flow rate at the 80% mark varying between 0.3 and 0.4. I would like to know if this is normal. A damper was also installed – does that mean it’s not possible to use a flow meter for measurement? Reward
Metering pumps are generally positive-displacement types, and fluctuations are normal. It is recommended to use cumulative flow meters rather than real-time flow meters
Not only is the flow rate variable, but the pressure fluctuates as well. At our outlet, we have a rotameter, and its pointer jumps up and down; the pressure gauge on the pump head does the same
I agree with the opinion from the second floor; a metering pump is a positive-displacement pump, and it has pulsations
