Installation guide
Installation guidelines for thermal energy meter Supercal 5
General
The static flow sensor and its calculator may only be operated within the conditions outlined
on the identification plate, as well as within the technical specification! In the case of ignor-
ing these default conditions, the manufacturer's responsibility is void and null.
The manufacturer is not liable for inappropriate installation and operation. Seals may not be
removed and/or only by authorized persons. The country-specific, local regulations, as well
as the manufacturer instructions, must be respected!
If the manufacturer's seal has been broken or damaged, the manufacturer cannot be made
responsible for the change of the verified and meas-uring relevant data.
When using several heat meters in an installation unit, fair heat consumption measurement
muss be chosen. All of them in the same types of device and installation positions
Before installation
 Check the design layout data of the installation.
 The pulse value of the calculator and the installation location must match the values
indicated on the flow sensor, consult the identification plate!
 The permissible ambient temperature range of the calculator is 5 – 55ºC.
 The installation and project prescriptions must be followed.
 The readability of the calculator and also the identification plates must be followed.
Remarks on the correct installation:
Conditions to comply with the directive 2014/32/EU (MID)
 The calculator is delivered as a heat meter as standard. If it is to be used as a cooling
meter or as a combined cooling/heat meter, this must be specified when ordering. Other
metrological parameters such as installation position or pulse value (Supercal 5 I only) as
well as non-metrological parameters such as M-Bus address can be parameterised with
the Superprog software before sealing. Please note that metrological parameters can no
longer be changed after the calculator has been sealed.
 The cable between the flow sensor and the calculator cannot be extended.
 All wiring must be installed with a minimum distance of 300 mm from heavy voltage and
high frequency cables.
 Radiated heat and interfering electrical fields close to the calculator must be avoided.
 In general, the calculator should be installed away from the cooling
 It has to be ensured that no condensed water can run along the wires into the calculator.
 If the danger of vibrations in the piping system exists, the calculator should be installed
separately on the wall.
 For temperatures over 90°C the calculator must be installed apart from the flow unit.
 The flow sensor should be installed between two shut-off valves.
 The flow sensor must be mounted with the measuring head to the side
 The flow direction of the flow sensor must be respected (arrow on the
flow sensor).
 Flush the pipe system before installing the flow sensors. To guarantee that no foreign
particles remain in the pipe.
 The flow sensor should be mounted BEFORE any control valve to exclude any potential
parasitic influences.
 During commissioning the pipe system must be purged. Air in the system of the flow
sensor may affect the measurement.
 Use only new and appropriate sealing material.
 Water tightness of the different connections should be verified.
The Supercal 5 is a compact calculator and consists of the following two partial units:
 Measuring and calibrating-relevant upper part
 Lower part
The pulse values of the calculator and of the flow unit, as well as the resistance value of the
temperature sensors (Pt500) must match. Compare the labels of the devices!
Cable connection
To connect the inputs and outputs the calculator's upper part must be removed. Shielded
cables must be grounded with a strain relief!

✓
It has to be guarantied that all grounding connections (line and power mains and chassis of

✓
the flow sensor) of the total installation are equipotential.
Power supply modules
The power supply modules are connected by means of a plug-in connector to the main board.
Power Supply at the Calculator
The Supercal 5 can be supplied with either battery or mains modules: D Battery 3,6 V, mains
24 V (12 VAC to 36 VAC or 12VDC to 42 VDC), mains 230 VAC (110 VAC to 230 VAC, 50/60 Hz).
These can be converted and retrofitted at any time.
The mains module is equipped with a backup battery already installed.
The electrical connection of the mains power supply modules
The electrical connection has to be done in accordance with valid standards, under consid-
eration of local safety regulations and by an authorized person. The electrical main is to be
made in such way that no hot parts (pipes etc. over 80°C) can be touched (danger with dam-
aged isolation). Water contact of the electrical connection must be avoided.
