P29 - - - - Blocking out of disturbing object FACTORY DEFAULT: 0
One fixed object in the tank, disturbing the measurement, can be blocked out. By the use of the Echo Map (P70) the precise distance of disturbing
object can be read out. This value should be entered in this parameter.
P31: - - - - Sound velocity at 20C (m/s or ft/s depending on P00(c) FACTORY DEFAULT:: 343,8 (m/s), 1128 (ft/s)
This parameter should be used if the sound velocity in the gases above the measured surface differs largely from that of in the air.
This is 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”.
P32: - - - - Specific gravity FACTORY DEFAULT: 0
Entering a value (other than “0”) of specific gravity in this parameter, the weight will be displayed instead of VOL.
Engineering unit should be [kg/dm
3
] or [lb/ft
3
] depending on P00 (c)
