Water Detection Warning Systems

Wet, slippery, and/or flooded roads are killers. Every municipality has area or roads that experience occasional flooding or become dangerous when wet. ELTEC’s low maintenance sensor detects both conditions forewarning motorists.


ELTEC’s system utilities a bronze-housed sensor positioned at the desired high water detection point. When water touches he stainless steel electrodes, an amplified signal activated the transmitter, which in turn activated the flashing road beacons. If the optional communication devices are used, messages are sent. The LEDs flash continuously as long as flood waters are detected.

Multiple sensors can be mounted on the detector pole or the bridge, triggering specific events with each level of flooding. For example, the lower sensor turns ON the flashing signals; the higher mounted sensor would lower the gates.

For areas prone to flooding or waters rising above the roadway, flood warning systems or high water signs may be required. ELTEC’s flood warning system utilizes a pole mounted, submersible sensor housed in galvanized piping. Once the water makes contact and rises above the sensor, two stainless steel electrodes close the circuit and activate the flashing beacons or transmitter. As long as the flood waters are detected, the activated LEDs will flash continuously to alert motorists.

While not all roads are flood risks, some are slip risks based on their shape, material, and condition. With an embedded roadside sensor, it’s possible to detect adverse conditions and activate “SLOW DOWN” or “SLIPPERY WHEN WET” warning signals to alert motorists.

ELTEC’s sensor is embedded in the pavement near the outer edge of the roadway shoulder, or if this is impractical, it can be installed in a concrete core alongside the road. Each sensor is level and flush with surrounding pavement, featuring up to 50 feet of wire to connect the sensor with nearby flasher systems.

Some curves on roads are extremely slippery when wet. A road side embedded sensor warns motorists to SLOW DOWN or SLIPPERY WHEN WET prior to reaching the area.

ELTEC’s sensor is embedded in the pavement near the outside edge of the roadway shoulder, or if impractical, installed in the concrete core alongside the road. The top surface of the sensor is level and flush with the surrounding pavement. The wire connects the sensor to the flashing beacon pole for distances up to 2000 feet.

Should an intersection experience frequent accident with the first sign of rain, the sensor can be connected to the controller triggering a longer YELLOW light duration. This allows more time for the cars to get (slide) through the intersection before the cross traffic enters.

Whether you are looking to enhance safety with solar powered pedestrian lights or need a comprehensive solution to your traffic concerns, ELTEC has the traffic control products you need.
