80GHz Radar Level Sensor PP Non-Contact Water Monitoring

Product Overview

The 80GHz Radar Water Level Meter is an advanced, non-contact measurement instrument engineered for highly precise liquid level monitoring in complex aquatic and industrial environments. Utilizing 76-81GHz Frequency Modulated Continuous Wave (FMCW) technology, this millimeter-wave radar delivers exceptional performance that surpasses traditional microwave or guided wave alternatives. By emitting a continuous, silent sweep of high-frequency radar waves, it achieves an extraordinary accuracy of ±0.02% FS and a highly focused narrow beam angle of ±4°. This concentrated signal ensures strong penetration ability, easily piercing through heavy condensation, thick foam, and airborne dust without losing signal integrity.

The physical construction features a dense, chemically inert PP (Polypropylene) housing paired with a resilient FKM sealing ring. When handled, the industrial-grade finish feels solid and weather-ready, purpose-built to resist severe chemical corrosion and environmental wear. Designed with IP67 protection, it thrives in environments with extreme high humidity (0-95% RH) and fluctuating temperatures ranging from -25°C to +60°C. Operating flawlessly under process pressures of -1 to 3 bar, the sensor requires a two-wire 24V DC power supply and outputs a standard 4-20mA signal alongside Modbus/Bluetooth (BLE5.1) communication protocols. This non-contact design fundamentally eliminates issues like debris entanglement or sensor fouling, significantly reducing long-term maintenance efforts. Operators can configure the unit wirelessly using the intuitive "RadarMe" mobile app or PC software, removing the need for a fragile built-in display screen.

Key Advantages & Operational Value

Ultra-High Precision & Core Technology

Operating on the 76-81GHz FMCW frequency band, this radar sensor provides an industrial-grade accuracy of ±0.02% FS, ensuring your water level data is consistently reliable. The highly focused ±4° narrow beam angle minimizes false echoes from tank walls, internal structures, or turbulent water surfaces. By utilizing millimeter-wave technology, the sensor maintains a stable signal even when measuring rapidly changing water levels in narrow pumping stations or deep wells. This precision helps facility managers optimize water flow, prevent overflows, and maintain strict environmental compliance.

• ±0.02% FS accuracy for highly dependable liquid level tracking.

• 76-81GHz FMCW technology paired with a ±4° narrow beam angle to minimize interference.

Resilient Material & Harsh Environment Adaptability

Traditional submersible sensors often fail due to water pollution, debris entanglement, or chemical degradation. This non-contact radar sensor avoids these pitfalls entirely. Encased in a durable PP housing with premium FKM sealing, the exterior feels solid, dense, and highly resistant to corrosive gases and aggressive liquids. The IP67-rated enclosure guarantees complete protection against dust ingress and heavy rain. Whether exposed to the freezing winds of a winter reservoir at -25°C or the sweltering heat of a tropical wastewater plant at +60°C, the internal electronics remain perfectly secure, ensuring a long, maintenance-free operational lifespan.

• PP housing & FKM sealing for superior corrosion and weather resistance.

• IP67 protection and a wide temperature range (-25°C to +60°C).

Advanced Connectivity & IoT Integration

Modern industrial facilities require smart, interconnected data systems. This sensor is fully equipped for the Internet of Things (IoT) era, featuring standard 4-20mA analog output alongside RS-485 and Modbus digital communication. This versatile array of connectivity options allows the radar meter to integrate directly into existing SCADA control systems, centralized data loggers, and remote cloud monitoring platforms. Facility operators can aggregate real-time liquid level data across multiple sites, enabling predictive maintenance, automated pump control, and comprehensive data analysis without overhauling existing infrastructure.

• 4-20mA + RS-485 output for flexible and direct system integration.

• Bluetooth (BLE5.1) & Modbus support, ensuring broad compatibility with industrial networks.

Easy Installation & Wireless Configuration

Field debugging has traditionally been a time-consuming task requiring physical interaction with the sensor in hazardous or hard-to-reach locations. By incorporating a built-in Bluetooth (BLE5.1) module, this device revolutionizes the setup process. Technicians can securely connect to the sensor using the dedicated "RadarMe" mobile app or specialized PC software from a safe distance. This wireless approach completely eliminates the need for a physical display module on the device itself, reducing potential points of failure—like cracked screens or water ingress through buttons—while making parameter configuration, offset adjustments, and real-time status monitoring incredibly efficient.

• Compact size (83×127mm) with G1.5” thread mount for quick mechanical installation.

• No display needed—fully operable and configurable via smartphone ("RadarMe" app) or PC.

Wide Application Coverage

Engineered specifically for complex aquatic conditions, this radar level meter is an invaluable asset across multiple sectors. In municipal wastewater treatment plants, it accurately tracks sludge and effluent levels despite heavy foam and corrosive vapors. For environmental monitoring, it provides critical data for open-channel flow measurement, river and lake water level tracking, and early warning systems for flood control. Industrial lift stations benefit from its ability to ignore floating debris and turbulence, ensuring pumps activate exactly when needed. The non-contact nature means the sensor never touches the medium, preserving both the water quality and the instrument's structural integrity.

• Ideal for water treatment, rivers, lakes, and industrial lift stations.

• Performs reliably in dust, foam, and high-humidity conditions.
