20 mA

100%

4 mA

The echo quality is the benchmark for measurement reliability. It describes the amount

of reflected energy and depends primarily on the following conditions:

• Dielectric constant of the medium

• probe type

• Distance between sensor and product

Low values increase the probability that the echo is lost through a change in measure-

ment conditions, e.g. angel s of repose or large measuring distance.

7.8

This function corrects the measured level by a constant value. The entered value is

added to the measured level.
