Product Description

Radar Ultrasonic Water Flow & Level Monitor

      The instrument compatible for the water flow and level monitoring, featuring 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. Operating on battery power, the device features easy installation, extended battery lifespan, 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 flow rate and water level.

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

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

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.
