NOT AN ORDINARY SEWER LEVEL MONITORING SENSOR
SEWER NETWORK LEVEL MEASUREMENT WITH MILLIMETRIC ACCURACY
LIDoTT® is a next generation ATEX sewer network level measurement sensor. It integrates ultrasonic level, pressure depth and temperature sensors into one compact device. LIDoTT® delivers high-quality data throughout normal dry-weather operating and either wet-weather or blockage induced surcharge conditions.
LIDoTT® is a unique, UK and Worldwide, patent-pending design. On rising and falling water levels, LIDoTT® seamlessly transitions from ultrasonic level measurement to pressure depth measurement and back again – delivering continuous data.
Detectronic is a leading supplier of water level sensors. Detectronics provide the most cost-effective and technologically advanced level measurement equipment in use today!
Their level sensors and depth monitors are used for capturing temporary and permanent level measurement in wastewater networks. The data provided can help to monitor spills and provide early flood warnings.
HOW IT WORKS
As the liquid level rises, the ultrasonic sensor is in charge. Once the level reaches the bottom of the pressure sensor, pressure reading starts and a calibration sequence begins.
By the time the level enters the ultrasonic dead-band, the calibration sequence is complete and the calibrated pressure sensor takes over, delivering continuous, accurate depth data.
CONTINUOUS MEASUREMENT
When the sewer network is stressed during storm weather events or by blockages, the LIDoTT® automatically switches sensor mode from ultrasonic (level) to pressure (depth) as the liquid level rises, seamlessly delivering high-quality network management data. This transition is transparent to the external data-logging device which needs only a single recording channel.
DATA COMMUNICATIONS
The LIDoTT® Sensor communicates using a number of serial protocols including Modbus and will connect to many compatible data loggers.
Real time monitoring helps you better understand your sewer network
Automatic sensor switching enables continuous delivery of high quality network management data.
Data logging device needs only a single depth recording channel.
Designed to be compatible with many manufacturers’ data loggers.

Data form a traditional ultrasonic depth data.
HIGH QUALITY DATA
Installed just above the flow to be measured within the sewer network, LIDoTT’s narrow ultrasonic beam delivers high quality level data with millimetric precision throughout normal operation and minor weather-induced events.
Should more extreme conditions cause the water level to rise close to or above the sensor, LIDoTT seamlessly switches
from ultrasonic level to pressure depth measurement right up to 11.500m above invert.
