Selection of CO2 gas flowmeter for acidic gases
Thread Content
The reaction produces a large amount of CO2 gas, along with a small amount of HCl； I want to install a flow meter on the exhaust pipeline to monitor the gas flow. The exhaust pipe is DN100; I’m not sure which flow meter would be suitable!
The flow range needs to be specified, along with temperature and pressure. That makes it easier to make a choice.
Does it contain a small amount of HCI gas? Many flowmeters can be used for pipes with a diameter of 100
25 m3/h, temperature 40°C, pressure at atmospheric pressure；
It’s hard to choose here; 1. Materials that can resist HCL corrosion are all very expensive. 2.25 m3/h is a bit small for a DN100 pipe.
Yes, I don’t have any good ideas; I came here to ask for help: lol
If it’s not important, just go with a pitot tube! The material can be tantalum or titanium
Thank you, I’ll check with the manufacturer: lol
If the pressure is not high, choose a PVC material orifice plate – it is corrosion-resistant and inexpensive; pair it with a tantalum diaphragm transmitter
PP orifice plates, double-flange anti-corrosion balanced orifice plates; for vertical pipes, 4F lined rotameters can be used.
