The FFVAV (Fernwärme- oder Fernkälte-Verbrauchserfassungs- und Abrechnungsverordnung / District heating or cooling consumption and accounting regulation) legally requires the use of intelligent and remote readable heat meters. Use this as your opportunity to realise efficiency gains through a data-driven optimisation of the network infrastructure and the elimination of manual processes.
Our way to digitalize your heat infrastructure is to replace the heat meters in the network with smart and LoRaWAN-capable meters and build a municipal LoRaWAN network. Alternatively, it is also possible to use NB-IoT. In this way, the meter data can be transmitted automatically at regular intervals to our IoT service platform, IoTree.
The network and consumption data can be transmitted fully automatically from IoTree via interfaces to your operative systems, such as the network control center and the billing software. The functions of IoTree also enable you to optimize the heating network based on the collected data. By significantly reducing flow and return temperatures, energy consumption and costs are sustainably reduced.
Read here how we implemented our solution together with Stadtwerke Göttingen:
"With PHYSEC, we have quickly and reliably set up a LoRaWAN network and put several use cases into operation on the IoTree data hub. We have been able to track short-circuit events in our medium-voltage network since 2018 and monitor the low-voltage network since 2019."
Haltern am See GmbH
"Connecting remotely readable heat meters to PHYSEC's IoTree platform enabled us to significantly reduce average flow and return temperatures and volume flow in our district heating networks. These optimizations result in high annual cost savings."
"The cooperation between Gelsenwasser AG and PHYSEC GmbH is always constructive, characterized by a very high level of technical competence and an open, trusting relationship with each other. With this background, we have already successfully implemented the LoRa®TLS project for efficient remote meter reading, which we will continue to develop together in the future."
