P29:
Blocking out of disturbing object
One fixed object in the tank, disturbing the measurement, can be blocked out.
Enter distance of the object from the transducer. Use the Echo Map (
P70
) to read out the precise distance of disturbing objects.
FACTORY DEFAULT: 0
P31:
Sound velocity at 20
C (m/sec or ft/sec depending on P00(c))
Use this parameter if the sound velocity in the gases above the measured surface differs largely from that of in air.
Recommended for applications where the gas is more or less homogeneous. If it is not, the accuracy of the measurement can be improved using
32-point linearisation (
P48
,
P49
).
For sound velocities in various gases see section “Sound Velocities”.
FACTORY DEFAULT: Metric (
P00
: “EU”): 343.8 m/s, US (
P00
: “US”): 1128 ft/s
P32:
Specific gravity
If you enter a value (other than “0”) of specific gravity in this parameter, the weight will be displayed instead of VOL.
FACTORY DEFAULT:
0
[kg/dm
