problem statement
There are numerous shaft meters spread around the city of Bregenz, which were traditionally read out via Wireless-M-Bus. Due to the low range of M-Bus, test runs must be carried out. In order to keep costs low, these often only take place once or twice a year.
The following problems therefore arose, among others:
- Timely evaluations were not possible due to the long intervals
- Leaks were discovered too late and thus caused high costs
- Upgrading to newer meters is very expensive
solution
Citymonitor's simple and cost-effective system enables the city to regularly forward M-Bus data using so-called LoRaWAN Bridges. The data is then sent to the Citymonitor dashboard, where it is displayed graphically and updated regularly.
If there are deviations from threshold values, such as water pipe bursts, the system automatically triggers an alarm. This not only reduces response times, but also costs, which can be very high due to undetected leaks.
benefits
- Low costs due to cost-effective LoRaWAN bridge
- No ongoing data transfer costs for meter connection
- Prompt notification in case of damage
- As a result, immediate response and prevention of high costs
- Good penetration and therefore suitable for shaft meters
- Low power consumption of the M-Bus Bridge — resulting in a long run time
- No need to power the bridge as it is battery-powered
trivia
Low-power networks, such as LoRaWAN, make it possible to connect M-Bus meters (water, gas,...) simply and maintenance-free and to pay for this without ongoing mobile phone charges. Depending on the location, the LoRaWAN Bridge can record several meters within a radius of up to 30 m away and then send the data via LoRa gateways several kilometers away. We would be happy to advise you on this.
Alternatively, Citymonitor also supports common LoRaWAN meters from manufacturers such as Zenner and Diehl. However, sensors from other manufacturers can also be integrated.
