3.4 Functional description
The ultrasonic energy meter is a static compact meter and a fully electronic measuring instrument
based on the ultrasonic metering principle. It is equipped with a data memory that enables comparison
of the previous months’ readings with the current readings. The data read by the calculator are shown
in the display. The display is provided with various windows as loop functions that can be called up in
succession to display the system information assigned to each window (e.g. energy amounts, water
amounts, current temperatures, maximum values).
The energy meter has 6 display loops: main loop, accounting date loop, info loop, pulse input loop,
tariff loop and monthly value loop. The individual loops are described in Section 8 “Operation”. Some
windows in a loop and whole display loops can be deactivated separately to make the window
structure clearer.
Various display windows comprise up to seven displays that change at intervals of 2 – 4 s.
The loops in the display are numbered from 1 to 6 to help the user find his way around quickly.
The main loop is programmed with the current data as default setting, e.g. for energy, volume, flow
rate and other parameters. It is not possible to change the order of the available data.

3.5 Power supply
Possible power supplies:
A cell, 3.6 V DC lithium battery, with a lifetime of 11 years (standard version, with radio)
D cell, 3.6 V DC lithium battery, with a lifetime of 16 years
Mains unit 24 V AC
Mains unit 230 V AC
Fig. C. Power supplies
1 A or D cell, 3.6 V DC lithium battery
2 Mains unit 24 V AC / 230 V AC
The various power supplies can be changed in the field.
NOTE
The meter switches automatically to power save mode if the button is not pressed for
approx. 4 minutes. The display is also switched off in this case, but can be switched
on again by pressing the button. Communication is maintained, e.g. over the M-Bus
or the optical interface. The meter does not switch to power save mode if an error
exists. The error is shown in the display as an error code.
Never connect between two phases if a mains unit is used, as this would destroy the
mains unit. The protective safety cover must be installed at all times. The cable is to
be fused at max. 6 A and protected against manipulation.
Used batteries must be disposed of at suitable collection points.

3.5.1 Battery
A 3.6 V DC lithium battery is fitted in the standard version. The battery is not to be charged or short-
circuited. Ambient temperatures below 40 °C extend the life of the battery.
DANGER
There is a risk of explosion if the battery is replaced with the wrong type of
battery.
3.5.2 Overview of the measuring rates
The following table shows the lifetime of the batteries depending on the standard measuring rates.
Customer versions can differ from the standard measuring rates in the measuring rate and battery
lifetime.
1: for “moderate” ambient temperature. Temperature above 35°C reduces the lifetime.
The temperature at storage of the meter in a warehouse shall be less than 35°C.
The calculation of flow and volume is will be done every 2 seconds
After that the display is updated every 2 seconds.
To save energy the meter tries to do all its operations like metering, calculation and updating the
display at the same time.

3.5.3 Mains unit
The mains unit indicates to the meter if mains voltage is present. If the mains unit fails, the back-up
battery (CR2032) in the mains unit provides the power supply for up to 1 year. This back-up battery
can be replaced if necessary. The LCD readings (on pressing button) and the date and time are still
updated, but none of the measuring functions work, incl. the flow rate measurement. Communication
still functions over the optional M-Bus, RS485 and RS232 modules or the optical interface, but this
reduces the life of the back-up battery. The integrated radio function is switched off in the event of
mains failure.
3.6 Calculator
interfaces
The meter is equipped as standard with a ZVEI optical interface. This is located on the calculator
below the display (Fig. D). This interface can be used for communication with the meter (using the
IZAR@SET software) and for checking the meter.
Communication uses the M-Bus protocol, for which the Bluetooth IZAR OH BT opto head is suitable.

The energy meter has two slots for extension modules, slot 1 and slot 2 (Fig. E). In addition, the meter
can be equipped with an integrated radio.

3 Fixing clip
NOTE
Inserting a module into slot 2 immediately disables the internal radio function!
The meter recognizes automatically which module is inserted. This is shown in the
display loop 3 based on a module code. See also point 6.2.1.
NOTE
If other external devices are connected to the meter, these must be of the safety
extra-low voltage (SELV) type and comply with EN 60950-1.
3.6.1 Communication modules
The meter supports three communication channels over the same or different interfaces. If the meter
has an integrated radio, it is possible to use the two slots for modules. The protocol is different for
each of the two modules and is preset ex works, but can be programmed to customer-specific
requirements using the IZAR@SET software. The content of the radio protocol is the same as the
content from slot 2. Each module has its own primary address. Both modules have one secondary
address, which is set to the serial number ex works. The meter is equipped with automatic baud rate
detection.
M-Bus module
The M-Bus communication module is a serial interface for communication with external devices (M-
Bus repeater), e.g. IZAR CENTER. It is possible to connect more meters to one M-Bus master.

14
Communication via radio
The integrated radio function is an interface for communication of predefined protocols with
Hydrometer radio receivers. The communication protocol is preset, but can be defined to a customer-
specific protocol using the IZAR@SET software. By default, the internal radio is disabled. When the
meter detects a flow, the integrated radio is enabled. If the meter detects a flow without an interruption
at least 3 hours, the radio stays on, otherwise it is switched off again.
RS-232 module
The RS-232 communication module is a serial interface for communication with external devices, e.g.
a PC. The transmission speed is 300 or 2400 baud. A special data cable is required for connecting this
module to the PC. (Order no.: 087H0121)
RS-485 module
The RS-485 communication module is a serial interface for communication with external devices, e.g.
a PC. It can only communicate at a transmission speed of 2400 baud.
L-Bus module
The L-Bus communication module is a serial interface for communication with an external radio
module, in which the M-Bus protocol is transmitted. It can be used for example if the radio range of the
internal radio is not enough.
3.6.2 Function modules
Pulse output module
This module contains connections for two pulse outputs, which can be programmed as desired using
the IZAR@SET software. The energy pulse output is marked as standard as “01 - ┴” on the module
and “Out1” in the display. The volume output is marked as “02 - ┴” on the module and “Out2” in the
display.
Pulse input module
This module has 2 pulse inputs for connecting 2 additional pulse meters, such as water meters, gas
meters or electricity meters. The possibility of programming the pulse value using the IZAR@SET
software enables volume or energy values to be displayed and transmitted remotely over a suitable
communication module. Initial meter counts can also be parametrized for these two pulse inputs.
Module IN-OUT
The Module IN-OUT is equipped with two pulse inputs and a pulse output, which can be programmed
as desired using the IZAR@SET software. Pulse input 1 is marked “I1 - ┴” on the module and “IN1” in
the display, pulse input 2 “I2 - ┴” on the module and “IN2” in the display. The pulse output is marked
“01 - ┴” on the module and “Out1” in the display. The pulse output on this module is not galvanic
isolated.
Analogue module
The analogue module has the size of 2 standard modules and has two 4-20 mA outputs. If an
analogue module is mounted in the meter, no other module can be installed. The internal radio is still
working. The connection cable between the main pcb board and the module has to be installed on port
1 (left slot). By default, the two analogue outputs are not programmed, the values can be programmed
with the IZAR@SET software (standard version).
