Highest Accessibility. Robust Ecosystem. Widest Adoption UI-1203 (Sensus Protocol) Specification for Smart Metering • Purpose: To send meter readings from an encoder to an external device like a radio transmitter or a handheld reading device. • Data format: It uses an ASCII-based, three-wire protocol that includes start, stop, and parity bits for data integrity. • Standardization: It was created by Sensus and adopted by the American Water Works Association (AWWA) as an industry standard, allowing meters from various manufacturers to be read by a single system. You can request a copy of the UI-1203 Standard from Xylem after signing an MNDA. • Functionality: A reading device sends a query to the meter, which responds with the current reading and the meter's serial number in the UI-1203 format. • Compatibility: Many modern AMR/AMI systems and devices are compatible with the UI-1203 protocol, often through protocol translators or "auto-detect" functionality.
