Diehl Metering’s first ultrasonic bulk meter

Share article:

By combining ultrasonic measuring technology with smart functions, HYDRUS 2.0 BULK not only provides extreme accuracy over its lifetime; it also delivers powerful connectivity. When used for the district or zone metering of water networks, it offers multiple benefits for water utilities, including reductions in Non-Revenue Water (NRW) and a more sustainable network. When used for billing, it also delivers extremely precise and reliable readings.


Lasting accuracy under tough conditions

When it comes to metrology, HYDRUS 2.0 BULK is designed to the highest standards. This is the first
bulk meter of the HYDRUS series to integrate Diehl Metering’s ultrasonic measuring technology,
meaning it is equipped with four transducers offering two measuring paths for extra precision.
The meter is capable of measuring extremely low and high flow rates, and has an approved dynamic
range of up to R1000. It can therefore register the volume of water supplied much more accurately,
making it a key part of an AMR (Automated Meter Reading) solution, and an AMI (Advanced Metering
Infrastructure) solution to help utilities improve billing and detect water loss.

Furthermore, HYDRUS 2.0 BULK is built to maintain its exceptional accuracy in the long term. The
static free-flow design means the meter has no moving parts, ensuring unobstructed access to water.
It is resistant to particles such as sand in the pipe, pressure surges, magnet manipulation and UV
radiation. Furthermore, its IP68 classification means it is also resistant to flooding and dust. This
robustness combines with a battery life of up to 16 years to ensure the meter’s longevity while also
limiting the need for maintenance. For utilities, this translates as peace of mind and cost savings over
the meter’s entire lifetime.


Water network insights through digitalization

The other flagship feature of HYDRUS 2.0 BULK is its integrated connectivity. As a smart meter, it
provides consumption and service data with high granularity. When integrated into a fixed network
metering structure, it supports water network monitoring in real-time. HYDRUS 2.0 BULK permanently
monitors consumption in order to detect leakage, backflow or overflow, and even comes with a selfcheck feature that instantly generates alert codes if implausibly different values are measured in the two measurement paths.


The full potential of HYDRUS 2.0 BULK is best exploited when it is connected to a system
infrastructure using IZAR radio technology. Based on the Open Metering System standard, it offers
optimal flexibility and data security, and is capable of exceptionally long-range radio performance, as
well as transmitting data from challenging locations such as pits. Furthermore, it supports a wide
range of technologies, including wired M-Bus, L-Bus and Pulse.

In a fixed network, multiple types of data are transmitted by HYDRUS 2.0 BULK in tandem with smart
domestic meters. This enables real-time information about flow rates, device status, and water losses
in zones or leakages in houses. As a result, IZAR software can build up a comprehensive overview of
the overall distribution network, with highly accurate monitoring and analysis. This empowers water
utilities to make smart, sustainable and fast decisions in order to optimize costs and resources, and
reduce Non-Revenue Water.
