Maddalena ElecTo SJ Digital Single-Jet Water Meter
Smart residential water metering with digital display, integrated radio communications and long-term battery operation.
The Maddalena ElecTo SJ is an electronic single-jet water meter designed specifically for residential indoor applications where accurate measurement and remote meter reading are required.
Unlike a conventional mechanical register, the ElecTo SJ uses an electronic radio register with a large digital LCD display. This provides clear local consumption information together with additional operating data for users, landlords, building managers and meter-reading operators.
Integrated wireless M-Bus / OMS radio allows the meter to be read remotely using mobile or fixed reading systems, making it particularly suitable for apartment developments, residential sub-metering and other applications where regular physical access to the meter is inconvenient.
