The Roots Dresser D630 Rotary Gas Meter combines compact design with utility-grade performance, offering a true drop-in replacement for traditional diaphragm meters. With an 8-1/4” center-to-center hub (ferrule) dimension, the D630 ensures interchangeability with legacy installations. The positive displacement design delivers precise and consistent gas measurement, backed by the rugged construction and time-proven reliability that Roots meters are known for.

Engineered for excellent low-flow performance, the D630 features a fixed, non-adjustable accuracy and an electronic display capable of programming fixed factor multipliers for elevated-pressure applications. The display provides volume accumulation and real-time flow rate information, and every unit includes pulse outputs at no additional cost.

Built for demanding environments, the D630 carries CSA Class 1, Div. 1, Groups A, B, C and D certification, meets IP65/IP66 moisture protection, and is manufactured in accordance with ANSI B109.3 for rotary type gas displacement meters.

Ideal for custody transfer (utility-grade) and submetering applications, the Roots Dresser D630 delivers accuracy, durability, and modern functionality in a compact, easy-to-install form.
