Overview
The Honeywell American Meter AC-250NX class meter was designed to be one of the industry's most cost-effective gas meters for residential compact metering, delivering high performance measurement at an economical price. Being one of the smallest and lightest diaphragm gas meters in the US market, AC-250NXS is reliable, accurate, easy to install and fits in tighter spaces, such as meter trees in apartment complexes. More than 90 million meters based on this measurement cartridge design have been sold worldwide. The AC-250NXS is available with built-in temperature conversions for accurate measurements. An integrated CAT-M1 cellular communication module enables automatic meter readings to be updated to utilities multiple times in a day to have real time insights of the gas consumption and meter health.
