How it all works:

how_it_all_works Your water meter will be part of the City's new automated reading system. This new technology will integrate all water meter reading, data storage and billing across the City of Toronto into one seamless system. Once installed, each water meter across the city will send data, several times a day, to a series of collection units. The data is then sent to a central server, which allows for fast, secure access and storage of all information.

All data contains only the water meter serial number and consumption data. No identifiable homeowner information is transmitted. The radio frequency used by the transmitter is a licensed frequency on which only water meters can operate.

Under the new system, all city households will pay for the water they actually use. The City will provide meters to those who were previously on a flat rate system and replace old existing meters with more efficient and up-to-date technology. Being aware of water use – and therefore being able to use water more efficiently – leads to benefits for all Torontonians.


RF output information:

  • Operating frequency of the water meter transmitter is an Industry Canada Licensed frequency of 450-470MHz
  • Unlike most electric smart meters, the water meter transmitter system does not form a communication mesh so the transmission time from the transmitter is extremely short, about 0.25 seconds, after that the transmitter turns off.
  • In a residential meter the transmitter will transmit 4 times a day
  • After the transmitter transmits for 0.25 seconds it turns off
  • When not transmitting data, the transmitter remains off
  • Total transmission time of less than 1 second - for the entire day
  • The transmitter output is 0.25W
  • The maximum allowable power density for a transmission is 0.311 mW/cm2 at 20 cm
  • The water meter transmitter power density is 0.000008 mW/cm2, at 20 cm, this is 38,000 times less than the maximum allowable limit
