Attach the end-cap.
3.5 To Rotate the Housing (Figure 3-2)
CAUTION: Do not rotate the electronics housing on the transmitter more
than 180 degrees relative to the pressure connection.
Two locking screws (hexagon socket screws) lock the electronics housing to
the sensor body. To rotate the housing, loosen both of the screws and rotate
the housing. When the angle is correct, tighten the screws.
Note: Do not remove the locking screws.
3.6 Impulse Piping (Figure 3-3)
The purpose of arranging impulse piping for the specific application is to
maintain a single phase of fluid in the piping and transmitter. Liquid applications
should maintain a liquid state and allow any air or gas formation to travel up
and away from the transmitter. Gas applications should allow the formation of
liquids to drain down and away from the transmitter.
The pipe or tubing used for connection must be rated for continuous operation
at the pipeline designed pressure and temperature. Threaded pipe fittings
create voids (where air can be trapped) and increase the possibility of leaks.
When installing the connecting tubing or impulse piping, the following apply:
•
Horizontally installed impulse piping must slope at least 75 mm per metre
(approximately 1" per foot). For liquid and steam applications the piping
must slope down towards the transmitter. For gas applications the piping
must slope down away from the transmitter.
•
Impulse piping should be kept as short as possible and maintained at
ambient temperature avoiding fluctuations and gradients.
