Rosemount 3095MFA Mass ProBar Flowmeter

The LCD readout states the following ERROR I/P OL. I have looked online for an error code description and have found nothing. Any help would be appreciated.

  I am not familiar with the "ERROR I/P OL". Similar messages are generally "ERROR DP OL" or "ERROR SP OL" referring to the differential or static pressure reading. The LCD message "ERROR DP OL" means that the differential pressure reading is exceeding its upper limit by more than 10% of the calibrated span. In short, the line is over pressured or you could be seeing freezing in the wet leg which can cause an increased DP. If it is frozen, I would recommend having a Rosemount Service Professional take a look at the device and see if it is damaged, it can be replaced by our new 3051S MultiVariable transmitter as the 3095 version is obsolete.
