The low side pressure port (atmospheric reference) on the in-line gage
transmitter is located in the neck of the transmitter, behind the housing. The vent
path is between the housing and sensor of the transmitter. (See
Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so that the process can drain
away.
