Installation instructions
WARNING
For pressure applications, it will be necessary to use PTFE tape or other appropriate thread
sealing compound, and to tighten the process connection beyond hand-tight. (The
maximum recommended torque for Threaded versions is 40 N-m (30 ft.lbs.) See Flange
bolting, Flanged encapsulated antenna only (Page 22) for FEA recommended torque
values.)
Note
•
On devices with a removable head, there is no limit to the number of times a device can
be rotated without damage.
•
When mounting, orient the front or back of the device towards the closest wall.
•
Do not rotate the enclosure after programming and vessel calibration, otherwise an error
may occur, caused by a polarity shift of the transmit pulse.
