To begin with you must ask why there was a DP measurement
in the first place?
For example if you are measuring the DP across a Filter to
find filter choked condition, then removing one capillary
will defeat the basic concept.
If the DP xmr is used for a level measurement, then also
you will get wrong reading.
So unless you inform the details... correct answer cannot
be given.
By keeping one side of the transmitter open to atmosphere
by removing one capillary, the other side will read the
pressure with reference to atmosphere.
If you want vacumm pressure measurement then you have to
keep the HP side open and LP to the process. Vice versa for
gauge pressure measurement.

If relative y axis vibration sensor is by passed, and relative x axis and absolute sensor is left working. how much monitoring i would have risked?

I have a steam flow DP transmitter that has output swinging. Steam valve is in manual.I have good steam pressure. The impulse lines have steam tracing on them. The steam tracing has a hole in it that is blowing raw steam on the high side impulse line only. Could this be causing the swinging?
