• Installation
Installing the DCR
The DCR-1005 and DCR-1006 should be installed using the 4 screws through
4 holes in the back of the enclosure. The enclosure must be mounted out of
direct sunlight.
Installing the DST
The DST sensor should be installed so that it has a clear sound path to the
intended target. Mount the sensor away from tank walls and inlets. The path
should be free from obstructions and as open as possible for the 9° off axis
beam pattern. Follow the guidelines mentioned in “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.
*Soft gasket
material is
recommended with
flange mounting.
