Electronic Water Ruler

The electronic water ruler is a water level measuring device that integrates a sensing sensor and a communication terminal, developed to address the issues of traditional digital sensors being easily affected by environmental factors, the inability to transmit data remotely, and high on-site construction costs in complex water level monitoring scenarios. It measures the water level data of the electrode by utilizing the weak conductivity principle of water. The device features high measurement accuracy, stability, reliability, ease of use, and automatic reporting, and can be applied to urban waterlogging, reservoirs, lakes, rivers, and irrigation areas.

Main Functions


  • Data collection: Collects water level information.

  • Working principle: Weak conductivity of water, stainless steel contact points.

  • Data storage: Processes, encodes, and stores the collected data.

  • Parameter setting: Supports local parameter settings, remote parameter settings, and Bluetooth wireless configuration.

  • Bluetooth communication: Built-in Bluetooth for on-site debugging.

  • Data retrieval: Supports remote and local historical data extraction.

  • Remote control: Supports local linkage and remote switch control output.


Product Features


  1. High precision measurement: Offers 0.5cm/1cm accuracy specifications.

  2. Scalable: Supports various combinations of 20cm/40cm/60cm/80cm/100cm units.

  3. IP68 waterproof and moisture-proof, protecting the device in harsh environments.


Application Scenarios


The electronic water ruler can achieve water level monitoring by installing on a pole. It includes a built-in data transmission unit and a lithium battery, solving the complicated construction issues in urban areas. It is suitable for real-time water level monitoring scenarios such as waterlogging under overpasses, reservoirs, rivers, lakes, agricultural canals, and irrigation canals.
