Flow meter issues
Thread Content
We are engaged in copper hydrometallurgy; flow meters need to be installed on the liquid streams used in the two-stage extraction process. The flow rate is around 300 cubic meters per hour, and the solution contains 5% copper sulfate. How should we choose the appropriate flow meter?
A float flow meter or an orifice plate can be used; 5% copper sulfate has a slightly acidic nature.
Copper sulfate is a relatively common solution; it is necessary to select instruments suitable for the process medium based on temperature, pressure, viscosity, density, and specific gravity.
5% copper sulfate has a slightly acidic nature; if the material is carbon steel, is it necessary to use one with a lining?
Electromagnetic ones should work! Both the lining and electrodes need to be acid-resistant. Last edited by yangxping on 2007-12-11 13:44]
It’s not just a matter of acidity; the reaction between copper sulfate and iron must also be taken into account!
The liquid is acidic, so the material of the flowmeter needs to be corrosion-resistant. It is also necessary to select an appropriate flow meter based on the diameter of the pipe through which the fluid is conveyed and the flow velocity within the pipe
