Flow meter selection
Thread Content
Hello everyone, I have a question regarding the selection of flow meters that I’d like to ask you: For HCl gas, with a pressure of 0.08–1 Mpa and a temperature of 20°C, the pipe specifications are φ426*8； The required range is between 1000 Nm3 and 3000 Nm3, with a precision of ±1. What type of flow meter should be chosen? I considered vortex flow meters before, but they can’t be lined with fluoropolymer; are there any other suitable options? How about orifice plates?
Mass flow meter? Now, mass flow meters are not expensive

Bro, it’s still a bit of a waste. There are cheaper options
Orifice plates won’t work as they cannot withstand HCl corrosion, and vortex flow meters are not resistant to vibrations; a thermal gas mass flow meter could be considered as an alternative
The process parameters seem to be incorrect; with a pressure variation of 0.08–1 MPa, which flow meter can achieve 1% accuracy? Moreover, the flow rate in a pipe with a DN400 diameter is less than 3000; therefore, it is not recommended to install a flow meter on such pipes. If the budget permits, it is advisable to use an average velocity tube. The HCL gas is relatively pure, but once leaks occur, its corrosiveness becomes very high.
