Intended use

The measuring capsule cooling meter type 4.5.1 serves exclusively for the physically
correct data collection of energy consumption. The meter is suitable for water circulating
(water without additives) in cooling systems (exceptions: see AGFW FW510). Alteration
of the meter is not permitted. When dimensioning and selecting the installation locations
for the volume measuring section and the temperature sensor, it must be observed that
typically for a cooling measurement only small temperature spreads and large volume
flows take effect.
!
If a sealed meter is damaged or removed by a person not authorised by Techem,
the calibration is no longer valid.
Safety and hazard information
• The regulations for the use of energy meters must be observed.
• The piping system must be fully earthed.
• Lightning protection must be guaranteed via the house installation.
• The distance between the sensor cables and sources of electromagnetic interference
must be at least 300 mm.
• Only clean the outside of the meter using a soft, slightly moistened cloth.

Power supply

Lithium battery (not a dangerous good), designed to last for the service life of the meter.
Cannot be replaced.
Device properties
• Meets the requirements of PTB Guideline TR K 7 .2
• Deliverable in measuring capsule geometry variant:
- TE1 : Techem
• The computer unit is detachable.
• Fixed, non-changeable connecting cables
• 2 free temperature sensors
• The meter is equipped with flow direction recognition. If the meter runs backwards, the
current flow is displayed with a "–" in front of the value.
• The meter is suitable for radio transmission (see TAVO online help).
Adjustable device properties when commissioning:
• The physical energy unit can be selected kWh <> GJ
• Installation location for the volume measuring section in inlet or outlet.
!
The adjustable device properties can only be changed during commissioning.
As of 10 kWh or 0.036 GJ, the parameters are fixed and cannot be changed any
longer.
