A 12° conical beam of ultrasonic energy is emitted from

the face of the transducer. The transducer should be

mounted in a location such that the ultrasonic signal does

not touch the side walls or any other obstructions in the

vessel. This is typically accomplished by using a bracket,

half-coupling, or rigid conduit to mount the transducer in

a spot where a strong echo can be received off of the

liquid surface. The chart below shows the distance the

transducer should be located away from side walls and

obstructions. The distances are based on a 6° beam radius

at different heights above the liquid surface. Generally

speaking, the transducer should be mounted one foot

away for every 10 feet of height.

CONFIGURATIONS

Figure 3 shows how the transducer can often be mounted

further down in a wet well or sump if the liquid will

never reach the top of the vessel. This helps to keep the

12 degree ultrasonic beam away from pumps, ladders,

side walls, or other obstructions in the vessel.
