CAT1 Wireless Radar Level Gauge: Integrated Solution for Outdoor Non-Contact Level Monitoring
In the fields of hydrological monitoring, flood control warning and municipal drainage, traditional contact level instruments face problems of corrosion, blockage and maintenance difficulties. The Nexisense CAT1 wireless radar level gauge is based on CAT1 cellular IoT technology and 24GHz FMCW millimeter wave radar measurement principle, adopting an integrated non-contact structure design, providing system integrators and project purchasers with a low-power, wiring-free, high-reliability remote level data acquisition and transmission solution. This product is particularly suitable for outdoor scenarios with inconvenient power supply and harsh environments, meeting engineering needs such as river channels, sewage pipe networks and natural disaster monitoring.
Product Core Technical Features
The Nexisense CAT1 wireless radar level gauge overturns the separate structure of traditional radar water level gauges, achieving high integration of sensor, power supply and communication module. The millimeter wave radar adopts FMCW frequency modulated continuous wave working mode, realizing precise non-contact measurement of the liquid level surface by transmitting linear frequency sweep signals and analyzing echoes.
The main technical parameters are as follows:
Operating Frequency Band: 24GHz
Beam Angle: 20 degrees
Measuring Distance: less than 30 meters
Blind Zone: 0.5 meters
Acquisition Frequency: 1 second (configurable)
Upload Frequency: adjustable from 1 hour to 24 hours
Battery Capacity: 9Ah high-capacity industrial lithium battery
Upload Method: timed upload or alarm value triggered upload
Upload Protocol: TCP transparent transmission, supports data encryption and protocol customization
Parameter Setting: infrared wireless setting, supports configuration of IP address, port number, domain name, alarm threshold, etc.
The product is small in size, low in power consumption, and has strong anti-interference ability. It is not affected by temperature, humidity, foam, floating objects or medium corrosion. The CAT1 communication module ensures stable data transparent transmission in areas covered by mobile networks, suitable for outdoor distributed deployment scenarios. The integrated design reduces on-site wiring and installation complexity, and the built-in battery supports long-term unattended operation.
Compared with NB-IoT solutions, CAT1 has certain advantages in data transmission rate and real-time performance, especially suitable for monitoring projects that require higher upload frequency or larger data volume.
Typical Application Scenarios
The Nexisense CAT1 wireless radar level gauge is widely used in outdoor level engineering projects that require non-contact and remote monitoring.
In river channel and hydrological monitoring, the product can be installed on river banks or bridge piers to achieve continuous water level measurement, supporting docking with flood control platforms and providing real-time data for flood warning.
Debris flow and mountain flood warning systems are one of its core application scenarios. The non-contact characteristics of radar avoid damage to the sensor from sediment and gravel. Combined with the alarm-triggered upload function, it can quickly push data to the monitoring center when the liquid level is abnormal, shortening response time.
In sewage pipe network and municipal drainage fields, the level gauge is suitable for monitoring key nodes such as inspection wells, pump stations and pipe network. Strong anti-interference ability ensures stable measurement in environments containing oil, foam or debris, supporting pipe network overflow, blockage warning and flow auxiliary analysis.
In addition, in scenarios such as water conservancy hubs, lake water levels and industrial open-air storage tanks, the product can achieve distributed multi-point deployment, with data uniformly uploaded to cloud platforms or local servers, facilitating centralized visual management and big data analysis. Many hydrological and environmental protection integrators have applied similar wireless radar solutions in actual projects, significantly improving system operation and maintenance efficiency and monitoring coverage.
Selection Guide
To match specific engineering working conditions, purchasers can refer to the following selection points:
Measurement range confirmation: Select the appropriate installation height within the <30 meters range according to the maximum liquid level fluctuation on site, reserve sufficient margin and consider the influence of the 0.5-meter blind zone.
Environmental adaptability: Evaluate on-site temperature, humidity, wind speed and electromagnetic interference. The product has strong anti-interference design, but in strong wind or rain/snow environments, it is recommended to choose appropriate installation angle and protective measures.
Communication network evaluation: Confirm the CAT1 (4G Cat.1) network coverage quality. In areas with weak signals, external antennas or combination with other communication methods can be considered.
Upload strategy setting: For conventional monitoring, 1-24 hour timed upload can be used; in high-risk areas, it is recommended to enable alarm trigger mode and set reasonable thresholds to balance battery endurance and data timeliness.
Integration requirements: Clarify target server address, protocol requirements and encryption level, and plan in advance the docking method with SCADA, GIS or early warning platforms.
Provide detailed working condition parameters (installation height, medium type, alarm requirements, network status, etc.), and the technical team can recommend the optimal configuration solution.
Integration Precautions and System Compatibility
The CAT1 wireless radar level gauge design focuses on engineering integration convenience and supports rapid deployment and platform docking.
Communication Integration: Adopts TCP transparent transmission protocol, which can directly push data to specified IP address, port or domain name server. Supports data encryption and custom protocol development, facilitating seamless integration with existing monitoring systems or cloud platforms. Integrators can realize data storage, alarm linkage and visual display through server-side parsing.
Power Management: Built-in 9Ah industrial lithium battery, supports low-power mode. Reasonable configuration of acquisition and upload intervals can extend the service life. It is recommended to optimize parameters based on actual on-site testing.
Installation Key Points: During non-contact installation, the radar antenna must face the liquid level surface directly, avoiding obstruction or large-angle tilt. The installation height should ensure no blind zone interference within the measurement range, and the fixing bracket must be stable and weather-resistant. The infrared setting tool facilitates on-site or remote parameter adjustment without opening the device.
Debugging and Reliability: After installation, use the infrared tool to complete settings such as IP, port, and alarm values, and perform end-to-end communication testing and measurement accuracy verification. When the network is abnormal, the product can cache data and automatically retransmit after recovery, improving system robustness.
In complex projects, edge gateways can be combined to achieve multi-device networking or protocol conversion. In terms of electromagnetic compatibility, the installation location should be away from strong interference sources.
