iSENSE Opti - Real-time network monitoring

iSENSE Opti enables real-time detection of changing conditions in the underground district energy networks, so that network can be controlled optimally based on accurate, measured data. This measured data also helps in detecting areas with exceptionally high heat loss, as well as areas which are cooled down due to unfavorable flow direction. The measured values are the network pressure, network temperature and vibration.

Measuring

iSENSE Opti sensor package:

Pressure measurement before and after the valve closing element

Data transmission

iSENSE smart monitoring product family uses the LoRaWAN data transmission network for data transfer. For those areas where there is no existing LoRaWAN network coverage, the network can be built regionally by the base station.

Benefits of LoRaWAN communication network for use in district energy networks:

wireless
energy efficient
good underground penetration
possibility of two-way communication
easy deployment in LoRaWAN coverage areas

Cloud service

Real-time monitoring of iSENSE monitoring solutions is done through the iSENSE Online cloud service. Cloud service is available from all devices, anytime, anywhere, with SSL-protected login.

Services

iSENSE product family is a turn-key monitoring service. Installation of the components, commissioning of the system and training is done by Vexve experts.

Installation and deployment

We take care of system installation in new construction and retrofit applications.

Measurement and reading

The system is real-time, remote, reliable and accurate. We take care of the correctness of the readings and the transfer of data to the cloud service.

Service and maintenance

We maintain a user-friendly interface and help with the interface solutions related to your system.
Our service organization ensures that the system is always up-to-date and in working order and that the components are of the latest technology.

Accessories: iSENSE Power – thermoelectric generator

Energy is produced locally using the temperature difference between the district heating supply pipe and chamber ambient (required temperature difference min. 25 °C).
Only one generator is enough to produce energy for both, supply and return line metering.
If the required temperature difference is not reached (eg. seasonal variation), the equipment will temporarily use batteries.
