Sonix is nothing short of a transformation in gas metering. Unlike

mechanical diaphragm meters, the Sonix digital design completely eliminates moving parts, relying instead on the proven technology of ultrasonics to measure gas flow. The digital design provides a host of additional advantages. It creates a platform for extensive diagnosticcapabilities and highly accurate temperature correction. Its compact size drastically reduces installation and labor costs and space requirements. A true expression of the principle that “less is more,” Sonix’s compact size and simple, no-moving parts design offers unprecedented levels of accuracy, reliability, andperformance available in no other gas meter all backed by a full 15 year warranty, the best in the industry.
