Software or system compliance: Sense MCE IBC is utilizing the following network assignment
technologies in line with the above directive:
▪ Polite Spectrum Entrance using collision detector
▪ Sense MCE IBC always transmit below the duty cycle due to limited usage to safe
power for the sensor.
5.6 Ultrasonic Fill level measurement
The fill level is measured using the piezo sensor for ultrasonic sensing measurements. More
information regarding the fill level measurements, are shown in Table 9:
