Installation Instructions
Threaded Version
1. Before inserting the device into its mounting connection, check to ensure the
threads are matching, to avoid damaging them.
2. Simply screw the device into the process connection, and hand tighten, or use a
wrench. A torque of 40 N m (30 ft.lbs) is recommended
Flanged Version
See
Flanged Horn
on page 9 and

1)
To equalize pressure and keep the liquid level in the bypass constant with the liquid
level in the vessel.
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.
Notes:
• The device can be rotated past 360° 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.
