Honeywell Elster SM-RI-X Turbine Gas Meter G2500 DN250 CLASS150 Natural Gas Flowmeter From Low to High Operating Pressures

Honeywell Elster SM-RI-X Turbine Gas Meter‌
A rugged solution for custody transfer and industrial gas measurement under demanding conditions (onshore/offshore). Proven for decades with exceptional accuracy and long-term stability, it is the industry standard for high-volume gas flow and a reference meter for global calibration labs.

Applications‌

Gas transmission, distribution, and industrial use
Full gas value chain: production to city gate stations
Large industrial/commercial consumers (e.g., power plants)
For sizes <DN200, use the TRZ2 model (DN50-DN150).

How It Works‌
Gas flow drives the turbine wheel, with revolutions proportional to volume. The X4X flow conditioner eliminates swirl/asymmetric flow from upstream bends, while a reduced cross-section boosts velocity and driving force. This enables precise measurement even at low flows/pressures.
