What type of field instrument is used to measure the flow rate of chemicals with high viscosity?
Thread Content
To measure chemicals with high viscosity, only an on-site flow display is required; what type of on-site instrument should be used? Can a metal tube rotameter be used? Are there any viscosity limitations for metal tube rotameters?
Positive displacement flowmeters are suitable for measuring fluids with high viscosity.
Float flowmeters require additional viscosity compensation when measuring highly viscous media; this is not necessary for things like engine oil. Target flowmeters are suitable for media with high viscosity and low flow rates.
Target or wedge flowmeters can be used, as well as volume flowmeters such as gear meters.
Do not transmit over long distances; only on-site display is required
A gear pump will do; there is on-site display.
Elliptical gear flowmeters or rotary piston flowmeters can be used for on-site measurement and indication; Coriolis mass flowmeters are also employed~~
