AQSense Multi-Sensor

A combined product with Hydrophone and Pressure sensor

AQS Multi-Sensor combines a hydrophone and a pressure sensor. The hydrophone trace leaks and triggers the pressure sensor to start recording 500 samples per second once there is a pressure transient (water hammer).

Features and Benefits

    Leak detection by hydrophone
    correlating sensors
    High-frequency recording
    of pressure transients
    Comprehensive pipe assessment
    information accumulated over time
    Continuous Pressure
    Intuitive web-based UI,
    integrating GIS information
    Advanced algorithms and big
    data analytics
    Designed for any pipe’s
    diameter and material
    Super sensitive acoustic sensor
    that allows installation at a great
    distance between sensors
    Battery operated,
    for 5 years of continuous work
    Cellular 3G/4G
