MDS-DLS5 Underground wireless road water accumulation detector

MDS-DLS5 Road Water Accumulation Gauge – Buried Ultrasonic Water Level Sensor for Flood Monitoring

-Product Overview-

The MDS-DLS5 Road Water Accumulation Gauge is an integrated embedded water level monitoring device designed for real-time detection of road surface flooding and water accumulation. Utilizing 2MHz ultrasonic measurement technology with a purely physical measurement method, this sensor delivers high-precision water level data without the need for calibration. With a measurement range of 0–2 meters and an accuracy error of just 1–2mm, it provides reliable, continuous monitoring for urban flood prevention and traffic safety applications.

Engineered for long-term submersion, the sensor features an IP68 protection rating and a rugged 304 stainless steel housing. Its compact, buried design eliminates the need for poles or wall mounts, reducing installation costs while preserving urban aesthetics. The sensor is equipped with a built-in 76Ah/3.6V battery for extended standalone operation and supports Modbus RTU protocol for seamless integration into IoT-based flood monitoring systems.

-Key Features & Benefits-

High-Precision Ultrasonic Measurement

Built-in 2MHz ultrasonic technology provides exceptional accuracy with an error of just 1–2mm within the 2-meter measurement range. The sensor reliably measures water depth even when fully submerged, as data transmission can penetrate through 2 meters of water.

No Calibration Required

The purely physical measurement method eliminates the need for field calibration, reducing maintenance requirements and ensuring consistent, reliable performance over the sensor's operational life.

Built-in Conductivity Measurement

The sensor integrates a conductivity measurement function, enabling simultaneous assessment of water presence and quality characteristics—providing additional data for flood event validation.

Long Battery Life & Low Power Consumption

Powered by a 76Ah/3.6V battery, the MDS-DLS5 supports extended deployment in remote or hard-to-access locations, minimizing maintenance visits.

Rugged & Submersible Design

Constructed with 304 stainless steel and rated IP68, the sensor is fully submersible and capable of long-term underwater operation in harsh environmental conditions.

Easy Buried Installation

The integrated embedded design allows for quick and convenient installation directly into the road surface—no poles, wall supports, or above-ground structures required. This significantly reduces construction costs and eliminates visual impact on the cityscape.

Standard Digital Communication

Supports Modbus RTU protocol via standard interfaces, enabling easy integration into existing SCADA systems, IoT platforms, and smart city infrastructure
