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.

HWM Multilog 2 is an advanced multi-channel data logger designed for continuous monitoring of flow, pressure and other key parameters in water distribution networks. The device can record both digital and analogue signals simultaneously, providing detailed insight into network performance, water demand and potential leakage. Multilog 2 supports NB-IoT, LTE-M, 4G, 3G and 2G cellular communication, allowing reliable remote data transmission to central monitoring systems or SCADA platforms. It is particularly suitable for DMA monitoring, PRV performance analysis, minimum night flow monitoring and detection of pressure transients or hydraulic events. The logger is built for long-term deployment, offering up to 5 years of battery life, remote configuration and firmware updates without the need for site visits.
