Home Our Equipment Water Level Sensors LIDoTT Alarm
Self contained water level measurement and alarm device.
LIDoTT® ALARM is a level measurement and alarm device which integrates the Level sensor, battery, modem and Detectronic’s unique Neptune antenna into one compact device. LIDoTT® ALARM alerts users to changes in wastewater depth enabling utilities to react quickly to blockages and surcharges caused by sewer collapses.
Alarm threshold set-points are configured on site during installation. A “return to normal” message is sent when levels fall back below the Alarm threshold.
5 min or 15 min Level measurement sampling rates can be configured.
Optionally, logging at 15 minute intervals is available at extra cost.
A daily heartbeat message verifies the sensor is operational.
LIDoTT® ALARM is simple to install and zero maintenance by design.
The enclosure is moulded from a carefully selected, resilient, naturally self-cleaning plastic polymer and is submersible.
ATEX and IECEx certified
Zone 0
LIDoTT® ALARM is ideal for widespread deployment throughout sewer networks, and in domestic or lateral sewers. LIDoTT® ALARM is also suitable for deployment across other water courses. It offers up to 3 configurable level states e.g. normal, high level and high-high level (green, amber, red). LIDoTT® ALARM continues to provide the status on alarms as the liquid levels return to a normal range.
The LIDoTT® Laser pointer is temporarily clipped onto the fixing pole during installation to identify the measurement target and ensure the ideal sensor mounting position. Once marked, the LIDoTT® ALARM replaces the laser pointer and is locked into place. The whole assembly is easily removed and replaced in exactly the same position should future access to the chamber be needed.
The LIDoTT® ALARM communicates using NB-IoT/Cat M1/M2 with 2G fallback.

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.
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.
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.
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.
