Product Description

Radar Ultrasonic Water Flow,Level and COD Monitor

      The instrument compatible for the flow,level and water quality(COD) monitoring, featuring battery-powered, ultra-low power consumption, IP68-rated and wireless communication. Suitable for monitoring sites with no power supply availability and in harsh environments (e.g., pipeline or manhole),      

      The users can view real-time data through a cloud-based platform. the device features easy installation, longlife span, and stable operation.

Features

1. Ultra-low power consumption, extended battery lifespan

2. Protection class IP68, waterproof and damp-proof

3. Integrates multiple measurement capabilities, including average flow velocity, water depth, and water temperature

4. Employs velocity-area method for flow measurement, achieving zero head loss while eliminating the need for constructing standard weirs/flumes

5. Using ultrasonic principle to measure flow velocity and flow rate, with high measurement accuracy and low initial velocity

6. No mechanical rotor structure, ensuring no interference with water flow and delivering higher measurement accuracy

7. Integrated with a built-in temperature sensor to compensate for the impact of water temperature on sound velocity

Functions

1.  Multi-level alerts
The system adjusts the data collection and transmission cycles based on rainfall and runoff flow requirements to meet rainy-day scheduling and monitoring data demands
2. Data Breakpoint resume
The device is equipped with breakpoint data resumption functionality, enabling data storage at interruption points during weak or no-signal conditions. It seamlessly resumes transmission of historical data from breakpoints to the monitoring system platform once network connectivity is restored.
3. Remote configuration
The pipeline flow monitor allows remote configuration and access to its operating modes and sensor parameters via the service platform. Additionally, device parameters can be configured locally via Bluetooth or directly on the device, ensuring simple and user-friendly operation
