The Rosemount 9175 provides a fully AGA compliant custody device delivered in a complete, integrated package. This natural gas flow meter is available in styles specifically accepted by the Bureau of Land Management (BLM), ensuring simplified inspections and regulatory compliance for critical energy infrastructure.
Designed for high-stakes differential pressure measurement, the 9175 features an innovative design that allows users to perform plate inspections and changes without removing the fitting from the line. This ensures maximum uptime and eliminates the need for flange spreading, effectively preventing gas leakage during routine maintenance.
This industrial instrumentation solution is available in 2", 3", and 4" line sizes with ASME RF Class 150, 300, or 600 connections. The carbon steel meter tube is built for durability in process temperatures ranging from -20°F to +160°F. By achieving concentricity in accordance with AGA 3/API 14.3 standards, the Rosemount 9175 delivers consistently accurate measurement for both liquid and gas fluid types. The assembled and configured delivery reduces on-site installation time and overall project costs.

When selecting a Rosemount 9175, the primary consideration is regulatory alignment. If your operation falls under federal oversight, ensure you specify the model accepted by the Bureau of Land Management to streamline your compliance audits. To further optimize your data acquisition, you can integrate the [Rosemount 3051S Wireless MultiVariable Flow Transmitter], which provides synchronized differential pressure, static pressure, and temperature measurements via a secure wireless network. While carbon steel is standard for natural gas, consult our technical team if your process involves specific corrosive elements that require alternative wetted materials.
The Rosemount 9175 arrives as a complete, integrated package, significantly reducing the risk of errors during on-site installation. To maintain the unit's AGA 3/API 14.3 accuracy standards, ensure the meter run is installed with sufficient straight-run piping to prevent turbulence. Because the unit is pre-assembled and configured, your team can focus on secure flange bolting and leak verification rather than complex component assembly.
Safety and uptime are maximized through the 9175’s unique fitting design. You can perform orifice plate inspections and change-outs quickly without removing the fitting from the pipeline or using flange spreaders. This design not only prevents gas leakage but also ensures that the plate remains perfectly concentric—a requirement for consistently accurate measurement. Regular inspections are simplified, supporting the high E-E-A-T standards required for modern natural gas custody transfer.
Q: Does the Rosemount 9175 meet federal requirements for natural gas measurement?
