Technical Description

The WTC-SR120L radar level gauge is a non-contact water and liquid level gauge designed with a microwave lens antenna. It has a built-in RTU module and lithium battery and meets the "Hydrological Monitoring Data Communication Protocol" (SL651-2014). Its operating frequency is 120~126GHz and adopts FMCW frequency modulation continuous wave system. It has the characteristics of high precision, low power consumption, strong anti-interference ability, etc. It can work stably all day long and is not affected by temperature gradients, cobweb condensation, water pollutants and sediments. influence, and the measurement results are accurate and reliable.

Features

● 120GHz FMCW frequency modulation signal with extremely high accuracy and resolution.

●  Integrated RTU module and lithium battery, working in standard mode for 3 years.

●  Extremely narrow beam angle, suitable for various narrow spaces and outdoor environments.

●  Non-contact measurement, not affected by mud, garbage, plants, etc.

• Why does 120-126GHz frequency ensure reliability in harsh hydrology sites?​

  • Industry-leading FMCW technology: ✓ ​Penetrates​ cobwebs, condensation & pollutants ✓ ​​±1mm accuracy​ despite temperature shifts or sediment ✓ ​Narrow beam angle​ avoids false echoes from tank walls/obstacles

• How does the built-in RTU simplify remote deployment?​

  • Self-contained hydrological monitoring: • ​Direct SL651-2014 protocol compliance​ (no gateway needed) • ​Lithium battery operation​ enables cable-free installation • ​All-weather stability​ from -40°C to +70°C
