Rotary gas meters are positive displacement flow measurement devices that use two synchronized, figure-eight-shaped rotors housed inside a precision measuring chamber. As gas flows through the meter, the pressure differential causes the rotors to rotate, and each full revolution captures an exact fixed volume of gas. The number of rotations is mechanically counted and translated into a volumetric flow total, which provides highly accurate gas consumption data regardless of changing flow rates or pressure conditions.

Rotary gas meters deliver exceptional accuracy because they measure a defined physical volume on every rotation rather than inferring flow from secondary variables such as velocity or differential pressure. Their mechanical positive displacement principle provides excellent repeatability and accuracy, often within narrow tolerance bands across a wide turndown range. This direct measurement approach makes rotary gas meters particularly reliable for custody transfer and billing purposes where precision is financially critical.

Apexmetertech rotary gas meters are designed with wide turndown ratios that generally allow accurate measurement from low minimum flow rates up to the meter's maximum rated capacity. The exact turndown ratio depends on the specific model and nominal size being selected for an application.
