The Sensus MeiStream RF is a Woltmann-type bulk water meter with integrated radio communication, designed as a metering endpoint for Smart Water Networks. It pairs the proven MeiStream metrology — MID pattern approval and a Q3/Q1 ≥ 100 measuring range — with a register that carries an on-board data logger, LC display and encrypted SensusRF radio, enabling walk-by/drive-by and fixed-network remote reading without exchanging components.
