Emerson, a leader in global automation technology, has introduced the Rosemount 9195 Wedge Flow Meter. This fully integrated solution consists of a wedge primary-sensor element, supporting components, and a selectable Rosemount pressure transmitter, providing a versatile tool for measuring process fluids across various heavy industries, such as metals, mining, oil and gas, renewable fuels, chemicals, petrochemicals, and pulp and paper.
Challenges in Flow Measurement
Accurately measuring volumetric flow in challenging conditions—such as highly viscous, abrasive, or clog-prone liquids, or extreme temperatures—has long been a struggle for industries. In addition, the need for heat tracing to maintain the flow of hot process media adds maintenance complexity. Traditional solutions often fail due to clogging or wear, requiring more energy and causing operational challenges.
Innovative Features of the Rosemount 9195 Wedge Flow Meter
The Rosemount 9195 Wedge Flow Meter addresses these issues with its unique design. The wedge element has no small passages, reducing the risk of clogging from entrained particles, and its abrasion-resistant construction ensures durability even under tough conditions. With the ability to measure highly viscous liquids accurately at low Reynolds numbers, the Rosemount 9195 is a reliable choice for these demanding applications.
Temperature Range and Heat Tracing
The meter operates across a wide temperature range, from -40°F to 1,000°F, and can be equipped with the Rosemount 3051S Thermal Range Expander for hot or viscous liquids. This eliminates the need for heat tracing, simplifying the measurement process and reducing maintenance efforts.
Seamless Integration and Flexibility
Offering flexible connectivity options, the Rosemount 9195 can be integrated into various control systems through 4-20 mA HART, WirelessHART, FOUNDATION Fieldbus, Modbus, or BSAP/MVS protocols. This ensures the transmission of process variables for real-time monitoring and diagnostics.
Versatile Connection Styles for Different Applications
The meter provides three connection styles to suit a wide range of applications:
Compact: Ideal for addressing plugging and cleaning concerns, featuring a saddle-style, remote-seal connection that reduces meter weight by 50%.
Flanged: Traditional style, used with flushing rings and valve assemblies.
Threaded: Designed for erosion or wear concerns, with a 1/2-inch NPT connection.
Customization for Various Conditions
Five optional application packages are available, including standard, abrasive, ultra-high process temperature, cold environment, and remote mount. These options ensure the meter is tailored to specific operating conditions, providing maximum flexibility.
Specifications and Compliance
The Rosemount 9195 is available in line sizes from 2 inches to 8 inches (50 to 200 mm) and features wetted materials of 316L stainless steel. The meter complies with ASME B31.3 and CRN safety standards, with the option for additional materials and sizes upon request.
Conclusion
The Rosemount 9195 Wedge Flow Meter offers a robust solution for industries that face tough flow measurement challenges. By combining innovative design with flexibility and durability, Emerson has provided a tool that ensures precise measurement even in extreme conditions, addressing a range of customer needs across diverse sectors.
