Digital Ultrasonic Water Meter With RS485 Output, Battery Powered, Flange Clamp

The Digital Ultrasonic Water Meter with RS485 Output, Battery Powered, Flange Clamp delivers precise, clamp-on water flow measurement for agricultural irrigation and water resource monitoring. Designed to install between flanges, it sits just 50 mm thick and uses a nylon-based all-plastic meter body for lightweight, robust performance. The unit is waterproof and immersion-ready, built to withstand muddy, sediment-laden water thanks to a 30 dB dynamic range and correlation-based transit-time measurement.

Built on a FLEXIM-like ultrasonic approach, the meter determines flow by analyzing the transit time difference of signals captured within the pipe, offering high precision, low drift, anti-interference, and reliable operation. It provides flexible outputs and protocols to suit remote monitoring and integration needs, including RS485 and infrared interfaces, with optional MBUS, Lora/NB-IoT via USART, and support for MBUS, MODBUS, ASCII, and CJ188 protocols. Pipe compatibility spans DN50 to DN150, and the device supports multiple flow units to match local reporting standards.

Key advantages include small size with lower failure rates, long service life, and the ability to display multiple data lines simultaneously (accumulated and instantaneous flow, signal strength, battery status, flow direction, and more). The meter is powered by a 3.6V 4Ah disposable lithium battery with a service life greater than six years, offers in-field software upgrades, and retains data for up to 10 years after power loss.

Benefits & Tips

• Ideal for remote irrigation systems where easy clamp-on installation saves downtime and labor.
• Choose from multiple communication options (RS485, infrared, MBUS, Lora/NB-IoT via USART) to fit your network.
• Use the selectable flow units (m3, gal, L, ft3, acre-foot) to match local reporting standards.
