ARAD Octave Ultrasonic SST 150mm Battery Operated Digital Water Meter

Ultrasonic digital water meter, 150mm SST body, battery powered, no moving parts, high accuracy, long-life performance

The ARAD Octave Ultrasonic SST 150mm Water Meter is a high-capacity digital flow meter designed for precise and reliable water measurement in municipal, industrial, and agricultural systems. Utilizing advanced ultrasonic transit-time technology, it delivers highly accurate readings with no moving parts, eliminating mechanical wear and ensuring long-term operational reliability.

Engineered for superior hydraulic performance, the meter offers excellent sensitivity at low flow rates while maintaining accuracy across a wide operating range. Its stainless steel (SST) construction provides enhanced durability and resistance, making it suitable for demanding environments and aggressive water conditions.

Powered by an internal lithium battery with up to 15 years of lifespan, the meter operates independently without external power. The integrated digital display provides clear readings of flow rate, total volume, and system diagnostics, with programmable units and flexible display configurations.

Designed for advanced water management systems, the Octave meter supports bi-directional measurement, built-in data logging, and multiple communication outputs including pulse, analog (4–20 mA), Modbus, and M-Bus. The IP68-rated enclosure ensures full protection against water and dust ingress, making it ideal for underground and submerged installations.
