Transforming Gas Metering with Even More Safety The Intelis 250 Gas Meter offers unparalleled accuracy, reliability, and flexibility. Building on the proven success of the original Intelis Gas Meter, the Intelis 250 Gas Meter features optional pressure sensing with automatic high-pressure safety shutoff. Weighing in at only 4.35 pounds, the Intelis 250 Gas Meter is the most compact and lightweight 250 Class gas meter available in the North American market. The Intelis 250 Gas Meter is equipped with an internal safety shutoff valve on the outlet of every meter. It delivers distributed intelligence to gas metering by providing the ability to self-monitor and shut off the flow of gas during a high-flow or highpressure incident, independent of operator involvement. Leveraging Intelis as part of a smart-gas communication platform enables utilities to automatically make intelligent decisions across the gas distribution network, delivering opportunities for operational savings and enhanced customer and employee safety by potentially preventing an explosion. KEY FEATURES » Optional autonomous high-pressure shutoff » Optional high-, low-, and tamperpressure alarms » Autonomous high-flow and hightemperature shutoff » High-flow and high-temperature alarms » Compact size » Integrated safety shutoff valve with a precision seal that meets or exceeds EN16314 gas tightness guidelines » Air-detection alarm » Embedded radio frequency (RF) communications » ±0.5% accuracy at room temperature » Highest intrinsic safety rating of UL Class I, Division 1 » Whisper-quiet operation

ULTRASONIC MEASUREMENT PRINCIPLE Ultrasonic meters are state-of-the-art technology and have been around for many decades, dating back to their introduction in the 1960s and commercial applications in the 1970s in Japan. The success of Intelis has been realized in the North American market, with Itron reaching its one millionth shipment in March 2023. The Time of Flight single-path measurement method used in ultrasonic meters is simple yet highly effective. It utilizes two transducers, one upstream and one downstream of the gas flow. One transducer emits an ultrasonic signal, while the other senses...

On-Board Self-Diagnostics The Intelis 250 Gas Meter features on-board self-diagnostics, such as monitoring transducer failure, remaining battery capacity, gas temperature, and pressure sensor failure. This ensures that the meter is always performing optimally or alerting utilities of potential issues. Long Battery Life Itron continues its long-standing tradition of superb battery life performance. The entire meter package has a 20-year battery life, including the meter, RF communications, and valve when using recommended parameters. Accurate and Reliable The accuracy of the Intelis 250 Gas Meter...
