Flow meter selection
Thread Content
Have any of you sea friends used flow meters to measure the flow of the following media? Could you help recommend a type of flow meter for handshake? The specific parameters are as follows: Process medium, Pipe material, Pipe size, Operating temperature, Operating density, Measurement range. Dichloroethane: 316, DN40, PN16; Normal temperature, 1.235 g/cm3; 0-3 t/h. Biphenyl dibromide: 316, DN32; Jacket insulation required; 100°C, 0.93 g/cm3; 0-0.5 t/h. Toluene: 316, DN40, PN16; Normal temperature, 0.87 g/cm3; 0-3 t/h. Epichlorohydrin: 316, DN40, PN16; 30°C, 1.18 g/cm3; 0-0.5 t/h. Ethanol: 316, DN40, PN16; Normal temperature, 0.789 g/cm3; 0-3 t/h. Diethyl malonate: 316, DN40, PN16; Normal temperature, 1.1 g/cm3; 0-3 t/h. Ethyl acetate: Fluorinated lining, DN50, PN16; 50°C, 0.9 g/cm3; 0-0.5 t/h. o-Fluoroacetophenone: 316, DN32, PN16; 50°C, 1.13 g/cm3; 0-1.5 t/h
I suggest you consider smart turbine flowmeters, metal rotor flowmeters, and elliptical gear flowmeters
What is the state of the medium – liquid or viscous? If money isn’t a concern, go with a mass flow meter
Direction? For low flow rates, a rotameter is more suitable as it offers a good cost-performance ratio. A few hundred kilograms might still require neck reduction
For the flow rate range you specified, a metal rotor flow meter is the best choice, as it can display the readings remotely from the site. Other types of meters such as turbine or twin-rotor meters may require a constriction to achieve more accurate measurements. You didn’t specify the operating pressure; it is likely to be low. If the operating pressure is high, vortex flow meters or mass flow meters can also be used.
If precision is required and money is no object, choose a mass flow meter
For flow rates where pressure is not too high, a rotameter can be used
For flow rates where pressure is not too high, a rotameter can be used
The pressure levels aren’t high; thank you. I’ve contacted several manufacturers, and all of them recommended using a metal rotor
