This flowmeter is designed for demanding applications
Measuring volumetric flow accurately and reliably is difficult for applications where the process liquid is highly viscous, extremely abrasive, prone to plugging, at high temperature, or a combination of these conditions. In applications with low ambient temperatures, hot process media, or a combination of both, heat tracing is often required, necessitating supply of electrical power, and creating a maintenance-intensive single point of failure. The Rosemount 9195 Wedge Flowmeter (photo) addresses these and other common measurement challenges with its unique design. The wedge element itself has no small passages that could plug due to entrained particles, and it is abrasion-resistant due to the shallow approach angle of the process liquid and the lack of critical sharp edges. Highly viscous liquids are measured accurately due to the linear response of the meter, even at low Reynolds numbers. The sensor’s operating temperature range is –40° to 1,000° F(–40° to 538°C), and the meter is available with a thermal range expander for measuring hot or viscous liquids without the need for heat tracing. Available line sizes for the sensor are 2 to 8 in. (50 to 200 mm). All wetted materials are 316L stainless steel, and the meter complies with ASME B31.3 and CRN safety standards. — Emerson, Shakopee, Minn.
