HYDRUS 1.3

Application

HYDRUS is a static water meter based on the ultrasonic technology. This technology enables accurate calculation of water consumption and eliminates measuring deviations caused by sand, suspended particles or air pockets.

Features

• Long-term stability under difficult conditions
• Leak and pipe burst detection
• MID approval up to R=400 (cold water) and R=160 (hot water)
• No straight line required
• No measurement of air
• Insensitive to scale and sand
• Installation in any position
• Battery lifetime up to 16 years
• Available in cold water version and hot water version
• Available with integrated radio 434 or 868 MHz, M-Bus or pulse
• Data communication in Prios, Real data or Open Metering protocol (selectable OMS Generation 3 profile A or OMS Generation 4 profile B)
