2.7 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
Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so the process can drain away.

3.0 Consider housing rotation

To improve visibility of optional LCD display:
1. Loosen the housing rotation screw.
2. First rotate the housing clockwise to the desired location. If the desired
location cannot be achieved due to thread limit, rotate the housing counter
clockwise to the desired location (up to 360° from thread limit).
3. Re-tighten the housing rotation screw (see
