Function (Fct.)
Input Range Description
2.0 CONFIG./TEST
2.1.0 OPERATION
2.1.1.0 BASIS PARAMETER
Enter 0 up to
60000 mm or 2362” 2.1.1.1 TANK HEIGHT
As per order
Tank height.
The tank height is defined as the
distance between the bottom of the
tank and the lower flange surface.
Enter 0 mm up to
< 24000 mm or
1063” 2.1.1.2 PROBE LENGTH
As per order
This value has to be equal to the
exact length of the probe. The only
situation for changing this value is if
the probe length has been changed.
Enter to
100 seconds 2.1.1.3 TIME CONSTANT
5 seconds
The time constant allows filtering of
possible signal fluctuations when the
product surface is turbulent.
2.1.1.4 DEAD ZONE Enter a value
Fct.1.5.1(Detection
delay) … probe
length.
Warning : Critical Parameter • Twin probe with
Probe length
<1 m or 3.3 ft
0.2 m or 8 in
• Single probe or
twin probe with
probe length
>1m or 3.3 ft
0.4 m or 16 in
• Coaxial probe
0 m or 0 in
Measurements near the flange may
not be precise or reliable.
Measurement may not be precise in
an area less than this recommended
value, depending on the probe type.
