Structure of the sludge level sensor (example: IFL 700 IQ)

Measuring principle

The IFL 70x IQ is based on the ultrasonic measuring principle. Ultra-
sonic waves transmitted by the ultrasonic transducer are totally or
partly reflected by layers at which the density of the measuring medium
changes (e.g. sludge blanket, bottom of the basin), and then received
again. Based on the reflection intervals, the distance between the lev-
els and the ultrasonic transducer is determined:

1

Wiper (only IFL 700 IQ)

2

Ultrasonic transducer

3

Marking for immersion depth 0.1 m

4

Shaft

5

Plug head connector

6

Leg supports
