Flow meter
Thread Content
Dear expert, what type of flow meter is suitable for installing at the outlet of a metering pump?
I’m not quite sure – after using a metering pump, is it still necessary to install a flow meter?
The conditions are insufficient; information on the specific environmental conditions and the measuring medium is also required.
A flow meter is usually not installed at the outlet of a metering pump; if one needs to be installed, it depends on the process conditions
Generally, a flow meter is not required at the outlet of a metering pump. Moreover, the information provided by the original poster is far too limited – what is the medium, gas or liquid, and what is the temperature? How can I help choose a flow meter under such conditions? According to what you said, a flow meter should be installed in front of the metering pump; so just buy a flow meter and install it:lol :lol :lol
The owner seems to have quite precise requirements regarding flow rate. Ordinary metering pumps provide a rather rough measurement accuracy. What the owner is referring to is the impact of the pulses generated by the metering pump on the flow meter – in other words, what kind of flow meter can function properly under the pulses from a metering pump! This requires consulting experienced production workers or instrument technicians
Well, if it’s the effect of pulses as mentioned above, the only solution is to use a buffer tank; after all, since the flow rate is fluctuating, how can the measurement results not fluctuate as well? If instantaneous flow rate isn’t required, you could try a positive-displacement flow meter; alas! In short, it’s necessary to clarify the process conditions and the purpose of the measurement in order to help you choose the right flow meter!
