What are the types of flow meters used for monitoring liquid flow?
Thread Content
What are the different types of liquid flow meters, and what are the differences in their application ranges, accuracy levels, and installation requirements?
Your question is such that it’s better to just read a book on instruments by yourself or do some searching on Haichuan. With such a vague question, it’s impossible to find a suitable answer.
I’ve also realized that the scope is too wide; I’m searching as well
There’s no need to search; just share which applications are used in your own field of work, along with their advantages, disadvantages, and any issues
For simple measurement purposes, glass rotameters are the most straightforward and inexpensive option; a signal conversion unit can also be added to output 4–20mA. Metal rotameters are much more expensive, but they can withstand higher pressures. There are also electromagnetic flowmeters, turbine flowmeters, etc.; please make a reasonable selection based on the site conditions and functional requirements. Feel free to ask questions
