Temperature probes for heat meter
Consistently rising energy costs and strict legal requirements demand highly accurate billing of the thermal energy used in heating or cooling systems.
One important component of heat and cold meters used for this purpose are the precise temperature probes for determining the temperature difference at the flow and return of the heating or cooling system.
Temperature probes for measuring the thermal energy, which are permissible for the demanding use in billing systems, are also available from us ready paired on request.
Testo Sensor GmbH not only produces temperature probes for heat and cold meters according to your specific specifications, but also keeps an eye on standards and guidelines for approval in accordance with regulations.

Temperature probe pairing according to DIN 1434
We provide you the probes and on request also the pairing
Special guidelines and strict quality criteria apply to temperature probes in heat and cold meters. This makes the manufacturing process and especially the pairing process very complex.
With this video, we would like to give you a small insight into our fully automated pairing process.
We will show you how we have managed to make the process both effective and cost-efficient while still complying with all standards and specifications.
This ensures that we can not only meet the extremely high requirements of the PTB, but also significantly increase the sensor throughput per hour.

Application heat and cold metering
Why are heat and cold meters needed?
According to the Heating Costs Ordinance, the energy consumption of the individual consumers in buildings in which several consumers share a heating or cooling source must be accurately recorded for billing purposes.
This enables service charge billing according to the source, a fair distribution of costs and the identification of potential energy savings.
The use of highly accurate heat and cold meters for measuring the flow and return temperature of the heating water has been mandatory since 2014. The less accurate methods of calculating consumption used until then are no longer permitted.
The smallest measurement uncertainties in determining the temperature difference lead to errors in cost accounting. These must be avoided at all costs.
The temperature probes used are very tightly specified in their tolerances and must meet high legal requirements.
The temperature probes from Testo Sensor not only meet all legal requirements, but also exceed them in some points that are particularly important for the application, such as response time or long-term stability.
For precise measurement of the heat energy consumed in each case, two measured variables are decisive:
1. The flow measurement.
For this purpose, flow meters integrated in the heating and cooling circuits record the respective amount of water flowing through per time unit in a counter.
2. The temperature measurement.
For this purpose, a temperature probe is installed in the supply and return pipes of the heating water, which measures the temperature of the water in the respective pipe. The temperature difference results in the extracted heat energy, which can be assigned to the respective consumer.
