within the vessel such as a supporting beam which would

interfere with the sound path between the transducer and

the material being measured.

NOTE

Ultrasonic sound waves are radiated from the face of the

Transducer within a cone of approximately 8 degrees.

The

Level Genie System

depends upon these sound waves reaching

the surface of the material to be measured and being re-

flected back along

this same

"sound path".

Any object

within this "sound

path"

that reflects an "echo" will

interfere with the

measurement of the material level.

For practical purposes the transducer should be located

one half bin radius from the side wall (assuming a center

fill bin.1

Position the transducer so that its radiating surface is

aimed directly at the material to be measured.

When

measuring liquids, the radiated beam or sound path must

be perpendicular to the liquid surface.
