Home Our Equipment Water Level Sensors LIDoTT Sensor
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.
LIDoTT® is a next generation water level monitoring 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, 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.
As a water level monitoring sensor, LIDoTT® is cost efficient and therefore ideal for widespread deployment. It can be positioned in sewer networks, in domestic sewer manholes and throughout other water courses.
LIDoTT® is simple to install and ultra-low maintenance by design. It requires no external atmospheric breather for its pressure-sensor.
The enclosure is moulded from a carefully selected, resilient, naturally self-cleaning plastic polymer and is submersible. LIDoTT® is safe to use in all environments being
ATEX and IECEx certified Zone 0.
When the sewer network is stressed during storm weather events or by blockages, the LIDoTT® water level monitoring sensor 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 datalogging device which needs only a single recording channel.
Ultrasonic level sensor
The LIDoTT® sensor reliably detects subtle changes in “normal” operating conditions – accurately delivering, for example, small silt-induced variations in Depth of flow.
“In Air” Temperature sensor
Primarily used to calibrate distance measurement for changes in air density, temperature can optionally be delivered to the datalogger as a measured parameter.
With its 10m H2O operating range, the pressure sensor deals with exceptional Depth measurement. LIDoTT® delivers seamless transition from Level measurement – using its Ultrasonic sensor, to Depth measurement – using its Pressure sensor. The pressure-sensor is activated and measures rising depth before the Ultrasonic sensor blanking distance (dead-band) is reached.
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.
The LIDoTT® Sensor communicates using a number of serial protocols including Modbus* and will connect to many compatible data loggers.

Self contained water level measurement and alarm device.
Detectronic‘s MSFM Lite combined liquid level sensor is specifically designed to measure the levels and depth of water in Combined Sewer Overflows. It can also be used for remote monitoring of tank and reservoir levels located in potentially explosive atmospheres certified to ATEX Zone 0.
Tipping Bucket Raingauge incorporates a high quality robust, reliable, precision measuring device and Detectronic’s MSFM GPRS Data Logger.
They combine to provide a fully automated transmission of Rainfall.
An open channel, non contacting flow meter designed for use with flumes and weirs.
The Orakel Primary device system is a non contact water level sensor. It comprises an ORAKEL controller and an external level transducer.
An intuitive and versatile flow module is built into the Orakel. It works by converting level readings to flow measurements using standardised formulas.
This product is particularly well suited to measuring flows through weirs and flumes.
