Selection of phosphorus trichloride flow meter
Thread Content
Gentleman experts, has anyone worked with phosphorus trichloride media? I need to choose a flow meter now. The one I was using before was electromagnetic (powered by 24V DC) and gave inaccurate readings. I’d like to switch to a different model; if anyone has used one or can recommend a suitable option, please help! Thank you! !
Why is it uncertain? What is the reason?
Regarding the phosphorus trichloride, which is our company’s raw material, I wonder whether its physical and chemical properties are similar to those of phosphorus oxychloride. Phosphorus trichloride has a very low dielectric constant, so electromagnetic methods cannot be used!
For the contact materials, measure the conductivity to see if it’s a problem with the gauge or something else. If it’s confirmed to be a conductivity issue, then just replace it; conventional types such as orifice plates and vortex flow meters will work fine……
Add me on WeChat. Wo Jie can overcome the problem of unstable dielectric constant, as it doesn’t require a dielectric constant of 15060667089. Send me your parameters and I’ll see if I can conduct a test
Is this medium highly corrosive? If not, turbine or vortex flow meters will work fine. If it is quite corrosive, then flow meters with corrosion protection features are necessary, such as those with rotors or PTFE turbines
I checked and it’s corrosive to metals; can a rotor flow meter with plastic lining be used?
For high requirements, use a mass flow meter; for lower requirements, use vortex flow meters, etc. Since the dielectric constant is very low, electromagnetic methods cannot be used.
This phosphorus trifluoride oxide is highly corrosive, has poor electrical conductivity; electromagnetic methods certainly cannot be used for measuring it. Special material turbine flowmeters should be employed to achieve high precision and corrosion resistance
