ARAD Octave Ultrasonic SST 50mm Threaded Battery Operated Digital Water Meter

Ultrasonic digital water meter, 50mm Threaded SST body, battery powered, no moving parts, high accuracy, long-life performance

The ARAD Octave Ultrasonic SST 50mm Water Meter is a high-precision digital flow meter designed for advanced water measurement in municipal, industrial, and agricultural applications. Utilizing ultrasonic transit-time technology, it delivers highly accurate readings with no moving parts, ensuring zero mechanical wear and long-term reliability.

Designed for superior performance, the meter provides exceptional sensitivity at low flow rates while maintaining accuracy across a wide measuring range. Its stainless steel (SST) construction ensures durability and resistance in demanding environments, including aggressive water conditions.

Powered by an internal lithium battery with up to 15 years of operational life, the Octave meter eliminates the need for external power sources. The integrated digital display offers clear readings of flow rate, total volume, and system status, with programmable units and data formats.

Engineered for smart water management, the meter supports bi-directional measurement, advanced data logging, and multiple output options including pulse, analog, and communication protocols such as Modbus and M-Bus. The IP68-rated enclosure ensures full protection against water and dust ingress, making it ideal for underground and flooded installations.
