• Installation
Installing the DST Sensor
The DST sensor should be installed so that it has a clear sound path to the
intended target. The path should be free from obstructions and as open as
possible. Follow the guidelines mentioned in this manual under “Understanding
Ultrasonics”, found on page 5.
NPT and Flange Mounting
• Mounting in a coupler or half coupler welded to the top of tank. (see
drawings below)
• Coupling should extend through the top of tank.
• Coupler must be aligned perpendicular to the target level.
• Screw sensor in only hand tight.
• To avoid false Echoes, the coupler should be installed where there is a clear
sound path perpendicular to the detection surface and where the sound
path will not intersect vessel fill spouts, rough vessel walls, ladders…etc.
BEST GOOD
*Soft gasket
material is
recommended with
flange mounting.
