- Operating instructions
Danfoss Sonometer 500 is an ultrasonic compact energy meter designed for measuring energy consumption in water systems. It can be installed in both horizontal and vertical pipe sections, provided air bubbles cannot collect in the meter. The flow sensor must always be filled with water. The minimum system pressure must be 1 bar to avoid cavitation. The energy meter should be installed in an accessible position for service and operating personnel.
Key features:
- Ultrasonic measurement technology
- Compact design
- Easy installation
- Battery powered
- M-Bus communication
- Display for energy, volume, flow rate, power, temperatures, operating days, error code, and display test

Following instructions refer to the ultrasonic energy meter.
The regulations on the use of energy meters must be observed!
The meter installation is only to be performed by an installation
and/or electrical contractor using personnel trained in the
installation and use of electrical equipment and familiar with the
Low Voltage Directive.
This installation guide is intended for trained personnel and
does not contain any basic working steps.
The specied medium temperature is 15…90°C. The medium is water.
If water additives are used (e.g. corrosion protection), the user must
make sure that the corrosion resistance is according AGFW FW510
specications.
The specied operation/ambient conditions are 5…55°C (<35°C ensure
the typical life of the battery); IP54; 93% rel. humidity.
Safety Note
The seal on the energy meter must not be damaged! A damaged
seal will result in immediate invalidation of the factory warranty and
verication. The cables supplied with the meter must not be shortened
or changed in any other way.

3. Installation of energy meter
Depending on the application, the energy meter is installed in
the forward or return pipe of the system. The installation location
is printed on the meter. The ow sensor must be installed so that
the direction of ow corresponds to the direction of the arrow
on the sensor. Calming sections are not needed before or after
the energy meter.
The energy meter can be installed in both horizontal and vertical
pipe sections, provided air bubbles cannot collect in the meter.
The ow sensor must always be lled with water.
We recommend installing the ow sensor in a tilted position.
The minimum system pressure must be 1 bar to avoid cavitation.
Make sure the energy meter is installed suciently far away
from possible sources of electromagnetic interference
(switches, electric motors, uorescent lamps, etc...).
To simplify the removal of the energy meter it is
recommended to install isolating valves before and after the
meter. The energy meter should be installed in an accessible
position for service and operating personnel.
Adapter for parallel calculator mounting and wall mount-
ing set are available as accessory.
Standard 90°C mounting Adapter for parallel calculator
mounting
Battery
3.6 V DC lithium battery is tted in the standard version. The
battery is not to be charged, replaced or short-circuited. Ambient
temperatures below 35°C ensure the typical life of the battery.

Instructions Sonometer 500
5. Installation of temperature sensors
M-Bus
The M-Bus communication is a serial interface for communication
with external devices such as M-Bus control center (e.g. IZAR-CENTER).
A number of meters can be connected to control center.
• The connection (MB) is not polarity-conscious and is electrically
isolated
• M-Bus protocol to EN 13757 standard
• 300 or 2400 bauds (auto baud detect)
• Current drawn: one M-Bus load
Tighten the plug screw with a torque of approx. 12 Nm
The operation of any violation of this guidance will result in
immediate invalidation of the factory warranty and verication.
6. Communication
Handle the temperature sensors carefully! The sensor cables are
tted with coloured type labels:
Red (TH): sensor in forward pipe,
Blue (TC): sensor in return pipe
The connecting cables must not be shortened or extended. One
temperature sensor is install in the body (direct). Other tem-
perature sensor must be also installed directly in a ball valve or
adapter for direct sensor mounting. Ensure that the temperature
sensors are permanently connected during operation.
For installation in a ball valve (same for adapter), see procedure
under item 1…5 below. Insert on O-ring in the sensor hole using
the mounting pin supplied.

7. Display
The various display windows comprise up to several displays that
change at intervals of 2 – 4 s. The loops in the display are numbered 1,
2, 3 and 6 to help the user nd his way around quickly. The main loop
is programmed with the current data as default setting, e.g. for energy,
volume and ow rate.
To show the data generated by the calculator in the display, various win-
dows are provided as loop functions that can be called up in succession
to display the system information associated with each window (e.g.
energy amounts, water volume, running days, water amounts, current
temperatures). The energy meter has 4 dierent display loops.

The push-button is used to switch through the various displays. The button
can be pressed for a short or long time. A short press of the button (< 3
seconds) switches to the next display within a loop and a long press (> 3
seconds) switches to the next display loop. The “Energy” window (sequence
1.1) in the main loop is the basic display. The meter automatically switches
o the display to save power if the button is not pressed for approx... 4
minutes (except in the event of fault) and returns to the basic display when
the button is pressed again.

Error description
C – 1 Basic parameter error in ash or RAM
E 1 Temperature range exceeds, e.g. sensor short-circuit, sensor
break
E 3 Forward and return sensor reversed
E 4 Hardware error in ultrasonic measurement e.g. transducer or
dive defective or short-circuit
E 5 Communication not possible (too frequent reading)
E 6 Water ows in the opposite direction, ow <0
E 7 No meaningful ultrasonic receive signal e.g. air in the measuring
path
E 9 Battery almost at; calculated lifetime expired
The error code is displayed in the main loop if an error
occurs. All the other windows can still be selected by
pressing the button. The error code display appears
again automatically if the button is not pressed for ap-
prox. 4 minutes.
The error display disappears automatically as soon as the
cause of the error has been cleared. All errors present
longer than 6 minutes are saved in the error log.
