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