SonicSens 3 is an intrinsically safe ultrasonic level sensor designed for wastewater and sewer network monitoring. Using intelligent ultrasonic technology, the sensor delivers highly accurate level measurements without making contact with the medium, reducing contamination risk and minimising maintenance requirements. SonicSens 3 is ideal for Combined Sewer Overflow (CSO) Event Duration Monitoring, surcharge detection and incident prevention. It records event occurrence, time and duration, supporting regulatory compliance and proactive network management. ATEX (Zone 0) certified, SonicSens 3 is suitable for hazardous environments. When paired with the ATEX Battery Pack, it supports accelerated sampling and increased dial-in frequency while maintaining up to five years of battery life.
