My tank full of Chlorinated Brine is under an average of 700 mbar of vacuum. I am using a DP level Transmitter to measure the level of this tank. The transmitter range is set to 24 kPa. The DP Transmitter suddenly failed while it was running. When the vacuum is turned on, the level of the tank decreases, while the Transmitter level increases. Why can you help?

 

please contact the supplier of the sensor, I'm sure they can send a manual or send and engineer for service.

 

Is the tank closed? Maybe the following article can help you.
