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 compariso n
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.

3.5.3 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.

NOTE
Insertin
g 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 a
re 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-Bu
s 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.
Page 14
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 customerspecific 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 met ers, 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).

6 Installation
NOTE
This installation guide is intended for trained personnel and does not contain any
basic working steps.
The meter may only be installed in dry and frost-free areas in buildings.
Avoid sharp edges (thread, flange, measuring tube). Only install and remove the
meter when the system is not under pressure.
Important! The seal on the meter (Fig. R, page 26) must not be damaged! A
damaged seal immediately invalidates the factory warranty and the verification or
declaration of conformity. The cables supplied with the meter must not be shortened
or changed in any other way.
Live parts may be exposed when opening covers or removing parts. Connection
points may also be live.
The regulations covering the use of energy meters and electrical installations must
be observed!
All instructions listed in the installation guide for the meter must be observed. A cold
leakage test by hydraulic pressure is to be carried out after installation.
The specified medium temperature is 5 ... 130 °C (150 °C). The temperature range
depends on variant and nominal size. The encapsulated variant is to be use d if
condensation is expected (cooling and heat meter with cooling tarif f ).
Only water without additives may be used as medium, according to AGFW leaflet
FW510 (Exception: Specifically programmed meter for medium Tyfocor LS). The
calculator has to be removed from the flow sensor at a medium temperature above
90 °C or if the water temperature is lower than the ambient temperature.
The IZAR@SET software is used for reading/parametrization and can
be downloaded from the webpage at http://www.hydrometer.de
DANGER
Do not touch live parts during installation work.
Risk of serious injuries or death!
The meter installation is only to be performed by an installation and/or electrical
contractor.
Personnel must be trained in the installation of medium-voltage electrical
equipment (up to 1000 V).

3. Connect the temperature sensor, see Section 6.1.3
4. Install the temperature sensor, see Section 6.1.4
6.1.1 Installing the flow sensor
NOTE
Thoroughly flush out the system before installing the flow sensor. It is recommended
that a strainer be fitted before the flow sensor or at another suitable position in the
heating or cooling circuit. The straight calming length of inlet pipe to the flow sensor
and the straight calming length of outlet pipe at the output of the meter may be 0 DN,
but an inlet pipe length of 10 DN is recommended before the meter for heating
systems without temperature mixing or with temperature stratification.
The meter can be installed in either horizontal (Fig. S, item 2) or vertical pipes
(Fig. S, item 1).
We also urgently recommend installing the flow sensor in a tilted position (45°) in
order to remove possible air bubbles from the circuit.

6.1.4 Installation of the temperature sensors
NOTE
The temperature sensors are to be installed symmetrically in the forward and return
line and preferably direct. The free temperature sensor can be installed in a ball
valve or in a pocket conforming to the requirements for this type of sensor. The
forward and return sensors must be inserted as far as the bottom of the pocket and
then fixed in position. For installation in a ball valve, a 5-piece coupling set is
enclosed with the meter in a separate bag. Bores in the flow sensor can be used for
symmetrical installation of the temperature sensors. In Germany, sensors up to
nominal pipe diameters of 25 mm are to be installed directly immersed.
If the temperature sensors are connected permanently, the cables must not be
shortened or lengthened. If replaceable conformity-marked temperature sensors are
used, the connecting cables must have the same length for the forward and return
line and not exceed 10 m; the cross-sections of the cables must comply with
EN 1434-2. They are connected to the marked Pt 100 or Pt 500 terminals in line with
the electrical compatibility of the integrator and finally sealed. The connecting cables
of the temperature sensors must be as short as possible. These cables are not to be
laid together with mains supply cables in cable ducts or cable racks. The minimum
separation of 50 mm for low-voltage cables must be maintained in accordance with
EN 1434-6.
Installation possibilities:
Installation in a ball valve with adapter (5-piece coupli ng set in separate bag)
Installation in a pocket
Installation in a ball valve with adapter
Use ball valves suitable for temperature sensor installation with M10 x 1.
1. Close the ball valve.
2.
Unscrew the plug screw from the ball valve.
3. Place an O-ring from the enclosed coupling set on the mounting pin (Fig. AA, item 2).

brass or plastic screw by hand (2-3 Nm) (Fig. AA, item 7).
Installation in a pocket
The po
ckets are best installed in T-pieces with a 45 ° or 90 ° angle. The tip of the pocket must point in
the opposite direction to the direction of flow and must be located in the middle of the pipe (Fig. BB,
item 1-5). The temperature sensors must be sealed after installation in the pockets.

8 Operation
8.1 Display
The meter readings are displayed with units and symbols on an 8-digit LCD.
8.2 Operation of meter
A pushbutton mounted on the front of the meter is used to switch to the various displays.
To show the data read out by the calculator in the display, various
wind
ows have been created as loop
functions that can be called up in succession to display the system information assigne d to each
window (e.g. amount of energy, operating hours, volume of water, current temperatures, … ).
The meter has 6 different display loops: main loop, accounting date loop, info loop, impulse loop, tariff
loop and monthly value loop.
The tariff loop (5) in a heating or cooling meter is switched off in the default setting. This loop is only
switched on in a heat meter with cooling tariff.
The window content of each loop is programmed with
the stand
ard information ex works. 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 (Fig. EE). The main loop
(1) is programmed with the current data as default setting, e.g. for energy, volume, flow rate.

12 Error analysis
The meter continuously monitors its own operation and displays various error messages. The error
code is displayed in the main loop if an error occurs. The permanent display shown corresponds to the
“normal” display (e.g. a temperature sensor error is not shown in the flow rate display). In the basic
display mode, the display changes between error codes 1, 4 and 7 and the basic display (exception:
error display “C - 1” is shown permanently). All the other windows can still be selected by pressing the
button.
The error display disappears automatically as soon as the cause of the error has been cle ared. All
errors present longer than 6 minutes are saved in the error log.
The following table shows the error codes indicated in the display with their respe ctive meanin g:
Error display Meaning
C - 1 Basic parameter error in flash or RAM
E - 1 Temperature measurement error
- Temperature range exceeded [-9.9 °C … 190 °C]
- Sensor short-circuit
- Sensor break
E - 3** Temperature sensors reversed in hot and cold lines
E - 4 Hardware error in ultrasonic measurement
- Ultrasonic transducer defective
- Short-circuit in ultrasonic transducer
E - 5 Reading too frequently
- M-Bus communication not possible for short time
E - 6** Wrong direction of flow
Flow sensor incorrectly installed
E - 7 No meaningful ultrasonic receive signal
