HYDRUS 2.0 RESIDENTIAL

HYDRUS 2.0 RESIDENTIAL

ULTRASONIC METER

Application

HYDRUS 2.0 RESIDENTIAL is a static water meter operating on ultrasonic measuring
technology. This technology enables accurate calculation of water consumption
with long-term stability and eliminates measuring deviations caused by sand,
suspended particles, scale or air pockets. Moreover it does not require any
earthing.
Developed within the framework of the MID, HYDRUS 2.0 RESIDENTIAL complies with
the European regulations and holds sanitary conformity certificates (ACS, WRAS,
BELGAQUA, DM174 and others). The meter is also designed for cold and hot
water.
Its integrated radio enables remote reading of the meter's index and alarms both
in mobile (walk-by, drive-by, passive drive-by) and fixed network mode.
HYDRUS 2.0 RESIDENTIAL offers a wide choice of connectivities compatible with the
different IZAR reading modes.
A complete Diehl Metering solution is thus available to meet your needs.

Features

    The HYDRUS 2.0 RESIDENTIAL saves 512 consumption values with a daily interval. This data can be read locally and accessed only by using the IZAR@MOBILE. As a second logging, a small amount of 32 consumption values can be stored. Both the radio protocol and the optical interface are encrypted by default.
