4.9 Supercal 5S Installation Considerations (including flowmeter)
Before installation

Check the layout and design data of the installation.

The calculator’s pulse factor and the installation location settings must match the
values indicated on the flow sensor - consult the identification plate!

The permissible temperature operating range of the calculator is 5–55 ºC.

The installation and project provisions must be followed.

The calculator faceplate and identification plates must be legible.

The flow sensor should be mounted BEFORE any control valve to exclude any potential
parasitic influences.

During commissioning, the pipe system must be bled of air. Air in the flow sensor may
affect the measurement.

Use only new and appropriate sealing material.

The watertightness of the different connections should be verified.

Lightning protection has to be guaranteed by the house installation.
Straight sections of piping of 3 DN in flow and return of any flow meter or heat
meter must be provided. For the Supercal 5 S up to DN 40 (qp10) straight sections
of 3 DN are already included in the length of the flow sensor.
4.9.1 Horizontal Mounting Position
Sensor heads MUST be placed to the side +/− 45° of the pipe axis to avoid the influence of
air (top) or dirt (bottom).
