Smart Metering of Water Meters with CardWare's M2M Architecture

In apartment houses where the number of water meters is relatively high, the architecture with the data gateway and repeaters if needed is the best choice

Water meter with a radio unit

Magnetic switch or optical pulse generation

  • Compact design

  • Two-way radio communication, ISM band

  • Power supply: Replaceable primary battery

  • Battery lifetime: 250.000 radio transmissions


Starting from 25 EUR

Data gateway

Provides the interconnection between the water meters and the remote data server. 

  • Two-way communication with the water meters (ISM)

  • Two-way communication with remote data server (GSM)

  • Mains powered with a UPS battery included

250 EUR

Data repeater

In case the quality of the radio propagation indoors is not good enough, a data repeater is introduced. The repeater forwards the data received, extending the range of the radio communication. The unit is mains powered with a UPS battery included. The repeaters can be programmed with a routing algorhitm.
