SAFETY INFORMATION
Before beginning installation works you must to read this document and follow its
instructions.
Caution: If this equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
The meter is powered from the battery (3.6 V), risk factors during the meter installation
and service is a heat conveying fluid flowing within flow sensor with inner pressure up to
2.5 MPa and temperature up to 180
0
C.
Only qualified technical personnel may install and maintain heat meters. Personnel must
be familiar with appropriate technical documentation and general safety instructions. It is
necessary to follow general safety requirements during installation and maintenance
process.
Device complies with safety class II. Protective grounding is not required, because
housing is made from plastics, and conductive parts are not exposed to the surface.
Safety guarantees at installation and service of meter is:
- Reliable insulation of electrical circuits,
- Hermetic fitting of primary flow and temperature sensors into the pipeline,
- Reliable fastening of sub-assemblies of heat meter at installation.
Safety requirements for temperature sensors are provided in appropriate technical
documentation.

Warning! Mounting of the sub-assemblies of heat meter is permissible only after ensuring
of absence of heat conveying fluid in the pipeline.
1. APPLICATION FIELD
The ultrasonic thermal energy meter QALCOSONIC E 1 is designed for measuring heating and
cooling energy and the recording of data in two separate registers.
It is intended for commercial accounting of energy consumption in objects of local or district
heating systems: in dwelling houses, office buildings or energy plants and the like.
The microprocessor compact heat and cooling energy meter can be mounted in both flow and
return pipe.
The meter is available with the inseparable pair of temperature sensors installed at factory or the
user can apply pair of temperature sensors which corresponds to requirements of Directive 2014/32/EU of
the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the
member states relating to the making available on the market of measuring instruments and has the type
examination certificate
Heat meter corresponds to essential requirements of the Technical Regulation for Measuring
Instruments, dated 30 October 2015
