Important information
Target group
• Qualified craftsmen
• Specialist personnel trained by Techem
Intended use
The ultrasonic energy meter type 4.1.3 serves exclusively the physically correct data
collection of energy consumption. The meter is an energy meter for universal use in sys-
tems for heat and cold measurement. The meter is suitable for water circulating in heating
systems (water without additives, exceptions: see AGFW FW510).
If a sealing or user lock of an installed meter is damaged or removed by a person not com-
missioned by Techem, this meter can no longer be used for legally compliant consumption
recording and the calibration become invalid.
Safety and hazard information
Ö The regulations for the use of energy meters must be observed.
Ö Observe the regulations for the use of pressure equipment in the hot hydraulic system area.
Ö The piping system must be fully earthed.
Ö Lightning protection must be guaranteed via the house installation.
Ö Clean the meter only from the outside using a soft, damp cloth.
Power supply
Lithium battery 3.6 V (not a hazardous good), designed to last for the service life of the
meter.
Power supply unit
A power supply unit can be retrofitted by a certified, skilled electrician at all times for the
use of the meter in control systems devices.
Power supply units with 230 V AC are available.
The power supply unit notifies the meter whether mains voltage is connected.
Even in case of mains voltage failure, the recording of the energy values including the
activated radio technology remains guaranteed.
Attention: Depending on the use of the optional interfaces, the device's working life can
be limited in case of mains failure.
Device properties
The energy meter is available in the following versions:
• Heat meter for heat energy measurement ( )
• Cold meter for cold energy measurement ( )
• Combination meter for the combined heat and cold energy measurement (heat with
declared conformity) (
• Marking the temperature sensor connected to the computer unit:
