Installation guide SonoMeter 30

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

1.3. Mounting of flow sensor

Pipe position: No limitations but avoid positions

where air can be collected.

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.

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):

Rotation in pipe axis: Flow sensor should be angled
in 45 to 315° to avoid air collection in flow sensor.
