DN80 Ultrasonic Flow Meter with RS485 Remote Monitoring

Designed for agricultural irrigation, garden management and water monitoring, this DN80 ultrasonic flow meter provides reliable flow measurement without moving parts that create significant pressure loss. Its IP68-rated construction and low-power operation make it well suited to demanding water systems and long-term monitoring.

Key Features

• Ultrasonic Measurement: Uses transit-time ultrasonic technology for accurate, non-invasive water flow measurement.
• DN80 Pipe Size: Suitable for DN50–DN150 applications, with this listing configured for DN80 systems.
• Wide Flow Range: Measures water flow from 40–250 m³/h for versatile irrigation and water-management applications.
• RS485 Communication: Supports RS485 connectivity for remote monitoring, data collection and system integration.
• Multiple Communication Options: RS485 and infrared interfaces are physically independent, with optional LoRa, NB-IoT, Wi-Fi and USART support.
• Clear Multi-Line Display: Shows cumulative flow, instantaneous flow, signal strength, measurement units and status information.
• Low Power Consumption: Designed for efficient long-term operation with less than 0.1 mW power consumption.
• Built-In Battery: Powered by a 3.6V lithium battery for convenient standalone operation.
• IP68 Protection: Fully sealed construction helps protect the meter against water and harsh environmental conditions.
• Pressure-Friendly Design: Supports working pressure up to 1.6 MPa while maintaining low pressure loss.
• Touch Controls: Two capacitive touch keys provide convenient sliding operation.
• Data Retention: Meter data is stored automatically and remains saved after power is switched off.
• Versatile Water Applications: Ideal for agricultural irrigation, garden management, raw water and water resource monitoring.
