Figure 3.5: Setting sensor parameters (changes only take effect after the system is rebooted).
The mounting height is defined as the height of a radar above the reference water level in
[m]. The reference point for measuring the height of each radar is the lower-side of the
radar mounting flange (as shown in Fig. 1.2). By default, the mounting height is set to
zero [m].
Tilt angle
The tilt angle, or the angular deviation from the vertical at which the radar is mounted,
is measured in degrees. It can be used to tilt the radar reflection footprint away from the
mounting construction. It is advised to only apply a tilt angle when it is really necessary.
Max. range
The range maximum in [m] is the maximum distance at which the sensor will detect the
water level. In general there is no need to modify this parameter. Yet in some situations
it is advised to set this parameter to a value lower than two times the distance from the
radar to the lowest expected water level. This is to avoid detecting multiple echoes of the
same measurement sweep.
Min. range
The range minimum in [m] is the minimum distance at which the sensor will detect the
water level. This parameter is used to avoid spurious measurements and should be set
depending on the installation location. If there are any nearby surfaces that can reflect the
radar signal the range minimum should be set to a value higher than the distance to those
reflecting surfaces. The range minimum parameter should not be lower than 2 [m] to avoid
interference with the internal reflection in the radar antenna.
Min. signal
The signal minimum is the lower limit for the signal power that will be considered in
water level measurements. This parameter is by default set to 25 [dB], and should only be
13
