Installation guide SonoMeter 40
1. Installation
1.1. Preparation
Only qualified personnel may install the equipment, following the requirements listed in this document.
More detailed instruction can be found on www.heating.danfoss.com.
Note! This product is approved for ambient temperature between 5-55° C, but to ensure optimal conditions for
battery it is recommended to install Calculator at max. 45° C. Avoid installation stress from pipes and fittings.
Flush the system.
1.2. Identification of installation: Return/Supply pipe installation and flow direction

Installation guide SonoMeter 40
1.3. Mounting of flow sensor
Pipe position: No limitations but avoid positions
where air can be collected.
Rotation in pipe axis: Flow sensor should be angled
in 45 to 315° to avoid air collection in flow sensor.
Inlet/outlet conditions (only for DN 65-DN 100)
In order to maximize performance it is necessary to have straight inlet and outlet flow conditions before
and after the flow sensor: 5 × DN on inlet and 3 × DN on outlet of flow sensor.

5 x DN 3 x DN
1.4. Mounting and sealing of calculator
Heat meter calculator may be installed in heated premises, working ambient temperature shall
be not more than 55 °C. It may not be exposed to direct sunlight.
The calculator is mounted on an auxiliary holder (it can be oriented in the required direction at an angle of
each 90 °:
The possible ways of the mounting of the calculator (auxiliary holder):
- Direct mounting on the housing of the flow sensor, by turning each 90o (only when the flow temperature
does not exceed 90oC):

Installation guide SonoMeter 40
- On the wall:
- Panel mounting on standard DIN-rail.
Important: It is prohibited to attach the electronic unit directly on the wall because there is a risk
that moisture may condense on the walls of the room or the temperature of the surface of the wall may
drop below 5 °C. In this case, it is recommended to mount the electronic unit so that to provide for an air
space of at least 5 cm between the unit and the wall surface.
Calculator seals
For design with permanently connected temperature sensors no additional sealing applies to the
electronic unit of a newly manufactured heat meter. Access to elements fixing the opening of the box,
configuration change activation contacts, and adjustment data change activation contacts is protected
by special easily breakable partitions.

Installation guide SonoMeter 40
After the opening of the box, change of the configuration, or adjustment of the meter (when the special
partitions were broken out for this purpose), the opened slots must be additionally sealed with sticker
seals:
- the two slots marked LOCK for access to the elements fixing the opening of the box are sealed with
test sticker seals (Fig. 4.1a),
-the slot marked SERVICE for access to the configuration change activation contacts is sealed with
the supplier’s sticker seal (Fig. 4.1b),
-the slot marked ADJ for access to the adjustment data change activation contacts is sealed with the
supplier’s sticker seal (Fig. 4.1c).
For design with changeable temperature sensors (IP65 protection class of the calculator only!) the
inspection seals /adhesive seals protect the access to protective cap mounting bolt and to adjustment data
change activation contacts ADJ, if breakable partition is broken out.
The inspection seals /adhesive seals protect the access to protective cap mounting bolt (1) and to

2. Electrical wiring
2.1 Connection of a meter with permanently connected temperature sensors (IP 67/68)
The meter version with permanently connected temperature sensors is fully ready for installation,
complete with the necessary cables for connection (no need to open the meter).
If the meter is equipped with wired interfaces or a pulse input / output function, appropriate and marked
cables to connect the relevant external device are provided.
If the meter is intended to be powered by an external source of 230V AC or 24V AC / DC, the dedicated
and marked cable of the meter shall be connected to the appropriate source.
2.2 Connection of the meter with changeable temperature sensors (IP65)
If the meter is fully assembled (temperature sensors are connected, communication interface cables are
in place) - follow the installation procedure in p.5.3.1 (the meter does not need to be opened). Otherwise,
it is necessary to open the electronic unit box.
Opening of electronic unit box
Before opening the electronic box, make sure that the meter version is with changeable temperature
sensors:
Check!
IP65 = Openable Version (with exchangeable
temperature sensors)
IP67 = Not openable
IP68 = Not openable

Wiring diagram 3
Design with changeable
temperature sensors, LoRa interface
and 24V power supply module.
The 24V power supply module is
mounted on the battery holder and
connected to the B1 connector of
the meter.
A backup battery is connected to
the BAT connector of the module.
The 24V power cable is connected
to the“24V”terminals of the
module (connections are made
before mounting the module, as
the connectors and terminals are
on the other side of the module).
The LoRa interface module is
connected to the 24V power supply
module connector by an additional
connection cable.
