High viscosity liquid flow measurement with control!
Thread Content
This post was last edited by zhaokun004 on 2010-1-19 16:21 For fluids with viscosity up to 10000mpa.s (centipoise), pipe DN25 (1' pipe), temperature 180 degrees (with steam jacket), normal pressure, what kind of flowmeter should be chosen? The price does not matter, the key is to have experience in use! In addition, a regulating valve must be controlled on this pipeline. What kind of regulating valve should be selected to control such high viscosity well (without blocking the pipeline)! Thank you very much!
Target flowmeter is more practical
I agree with the point above. Our company generally uses intelligent target flowmeters for high-viscosity fluids, which can withstand high temperatures and are basically maintenance-free.
Using a Coriolis mass flow meter, personal feelings.
For a pipe with such a small diameter, use a positive displacement type.
The price doesn't matter, you can ask someone for advice on oval gears. I heard they are effective for high viscosity gears.
It’s best to use a mass flow meter! We have this application
Positive displacement flowmeter, or wedge flowmeter

Mass flow meters are more effective but more expensive. I have never used a target flow meter, but it should work based on the principle.
The wedge flowmeter is better. We use this for all heavy oil installations, and the maintenance is low. It’s good!
