Seeking advice on using differential pressure transmitters to measure liquid levels
Thread Content
What’s causing liquid in the gas phase of the transmitter pressure guide tube? It used to work fine before, and the same problem persists even after replacing the three-valve assembly. Does any expert have a solution?
What is it measuring? The liquid phase formed by condensation due to low temperatures, I guess. Try implementing insulation measures, or change the direction of the pressure tap, along with its angle
If liquid condensation persists to form in the gas phase pipe, the solutions are: 1. Provide heat tracing for the gas phase pipe； 2. Add an isolation tank to the gas-phase pipe and fill it with an isolation fluid to keep it in the liquid phase at all times.
Propane tank – this phenomenon occurred after the last propane unloading. Why?
The propane in this tank is of poor quality, containing water or other heavy components.
I suggest you add a condensation tank after all
The condensation tank has not been used, and electric heating should also be able to solve the problem
Don’t propane storage tanks have a water cut-off valve?
This thing is used in many places
It is recommended to use a capillary double-flange level gauge, or fill the negative pressure side with liquid and install an isolation tank at the outlet of the pressure-taking port on that side. This solves the problem of liquid on the negative pressure side.
