Highest Accessibility. Robust Ecosystem. Widest Adoption UI-1203 (Sensus Protocol) Specification for Smart Metering The American Water Works Association (AWWA) has adopted this protocol as the industry standard for North America. Three-wire interface: • Red wire: Clock and power (mostly 5V) • Green wire: Carries the data • Black wire: Ground Pulse is a widely adopted solution for reading mechanical water meters. Two-wire interface: • Red wire: Pulse output • Blue/Black wire: Ground North America – UI1203 Sensus Protocol Pulse solution ABSOLUTE reading from the register (No Sync issue) 3-Wire PULSE output requires an accumulator to count pulses (Sync issues) 2-Wire
