Design
The M-Bus water meters fulfil the requirements in the M-Bus standard EN 13757:2013 as well as the
OMS TR02:2015 and can be used in a wide variety of applications using M-Bus protocol.
3.1
Applications
The M-Bus water meters are designed with focus on high flexibility to fulfill a wide pallet of existing and future
applications.
3.1.1
Analysis
The flowIQ® 2101/3100 support high quantities of data and all relevant data for analysis can be read out.
This is valid for both actual meter data as well as for target data.
3.1.2
Billing
All relevant data for billing purposes can be read out from the flowIQ® 2101/3100.
3.1.3
Emulation
The wired M-Bus datagram in flowIQ® 2101/3100 is fixed and cannot be altered
3.1.4
Controlling and regulating
The water meter can deliver online data in intervals down to 15 seconds (however at reduced battery lifetime) for
controlling and regulating purposes with a high communication speed.

Installation
As M-Bus is polarity independent there is no + and ÷ to care about.
Configuring the primary address can be done with METERTOOL HCW using an optical readout head or via the
M-Bus network. It is recommended that the entire M-Bus system is not powered up during installation of new M-
Bus water meters.
