Home Our Equipment Water Level Sensors LIDoTT Sensor U
LIDoTT® is a unique, UK and Worldwide, patented design.
On rising and falling water levels, LIDoTT® seamlessly transitions from ultrasonic level measurement to pressure depth measurement and back again – delivering continuous data.
The LIDoTT Sensor U is a next-generation water level monitoring sensor, designed to deliver millimetric accuracy. Its unique capability to seamlessly transition between ultrasonic and pressure-based level measurement ensures high-quality data during both dry-weather conditions and wet-weather events, enabling comprehensive sewer and drainage system monitoring.
The LIDoTT Sensor U integrates two key sensors—ultrasonic level and pressure—into one compact unit, making it ideal for wide-scale deployment across sewer networks, culverts, and open channels. This dual-sensor approach ensures continuous data capture even during surcharge conditions, providing high-quality insights into network performance.
The LIDoTT Sensor U employs advanced sensor technology that automatically switches from ultrasonic to pressure depth measurement and vice-versa, delivering continuous, high-quality data. This feature is crucial for maintaining consistent performance as water levels rise and fall.
When connected to the Detectronic Smart Datalogger, the LIDoTT Sensor U can also capture ambient temperature data for enhanced calibration of ultrasonic readings, ensuring superior accuracy and system diagnostics. This capability is unique to the LIDoTT when integrated with the Smart Datalogger.
Housed in a self-cleaning, resilient polymer casing, the LIDoTT Sensor U is built for long-term durability and ultra-low maintenance. It’s submersible and safe for use in the harshest environments, carrying ATEX and IECEx Zone 0 certification.
For added convenience, it requires no external atmospheric breather for its pressure sensor and can be equipped with an external battery and antenna for challenging locations.
