8.5 Input (3.)
Empty rate /min (EMPTY RATE) (3.5.8.2.)
Defines the maximum rate at which the reported sensor value is allowed to decrease. Adjusts
the LR460 response to decreases in the actual material level. Empty Rate is automatically
updated whenever Response Rate is altered.

Echo information (ECHO INFO) (3.6.)

8.5.6.1

Level transducer block (TB VALUES) (3.6.1.)

The output from the Level Transducer Block can be called the Primary Value (or Secondary
Value). When it becomes the input to the AIFB, it is called the Process Variable.
Sensor Value (PV) (3.6.1.1.)
The default value for level (in level units).
Open the menu View – Display, and select the tab Measured Value (Secondary Values).
Secondary Value 1 (SV1) (3.6.1.2.)
Equivalent value to PV (level).
Secondary Value 2 (SV2) (3.6.1.3.)
The value for distance (in sensor units).
Open the menu View – Display, and select the tab Measured Value (Secondary Values) and
see Sensor Value.
8.5.6.2

Echo quality (ECHO QUAL) (3.6.2.)

Echo Confidence Long (ECHO CON L) (3.6.2.1.)
Measures echo reliability. It displays the echo confidence of the measurement echo from the
last shot. Confidence Threshold defines the minimum criterion for echo confidence.
