2.1.5 In-line gage transmitter orientation
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
2-11).
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.
