Vexve iSENSE product family
The real-time measurement data provided by the iSENSE product family helps to improve network efficiency, provides tools for condition monitoring, and enables fast leakage detection. All iSENSE metering solutions are suitable for wireless underground usage. The products are self-powered and can be retrofitted in existing district energy networks.
iSENSE OPTI enables the real-time detection of changing temperature and pressure conditions in the underground networks. Areas cooled by high heat loss and unfavorable flow directions can be located in the network and can be adjusted using precise measurement data.
iSENSE PULSE enables fast and precise leakage detection based on pulse technology via Nordic alarm wires. Leakage detection is based on reflections of the pulse and the leakage is located based on the traveling time of the pulse in the wires
iSENSE CHAMBER enables effective online chamber monitoring. Maintenance operations can be effectively directed to the right chambers.
Step 1: Aistin Frame
From the idea into Proof-Of-Concept using Aistin platform modules
Device requirements and LoRaWAN radio technology were tested by using a proof-of-concept design built utilizing Aistin platform modules for the first pilot use cases. Demanding environmental conditions set the performance and durability requirements for the sensors.
- Real-time detection of changing temperature and pressure conditions in the underground networks
Step 2: Aistin Optimizer
The product idea got the name iSENSE and new features were gathered and specified after the pilot phase.
Further product development, research, and customization project were started and new features were specified:
- Customized Cloud Solution with new functionality
- Leakage detection based on pulse technology via Nordic alarm wires
First deliveries to several countries ensured that data transfer is fluent no matter where the IoT devices are installed.
Step 3: Aistin Production
Mass production and customer support
iProtoXi is taking care of the mass production of the third-generation design and productized iSENSE product family.
The amount of needed support work is reduced by 50-70% since the early phase solution when development efforts are targeted to selected automatization. This is a clear indication that customization of solutions brings significant cost savings in the long term.
- Service and support
- Maintenance and further development – IoT as a service
Vexve iSENSE product family consists of smart monitoring solutions specifically designed for underground district heating and cooling networks.
