I would like to ask experts: can a conductivity meter be used to measure pure propylene?

Thread Content

The customer’s designed process involves using an online conductivity meter to measure the water content in pure propylene (99.7%). The entire process design has already been completed; therefore, I am not asking here whether this approach is effective or not. Since the customer is a chemical company and propylene at this concentration is a flammable and explosive substance, safety comes first. What I would like to ask is whether conductivity is suitable for such conditions? Could it pose a danger? (It’s fine that all parts of the transmitter are designed to be intrinsically safe; the key issue is the probe that comes into contact with the liquid.) Emerson states that the probe does not carry any electricity and therefore poses no risk, while Mettler claims that the probe has a very weak current flow, but still no danger. However, this doesn’t dispel the customer’s concerns. Conductivity meters are primarily used for measuring water, so in fact, there aren’t many cases where these two brands’ conductivity meters have been used to measure flammable or explosive substances. That’s why I turned to experts online for advice; thank you for your guidance
