Vortex Flow Meters Rosemount

Vortex Flow Meters Rosemount

Vortex Flow Meters Rosemount offers many advantages for flow measurement including easy installation without impulse lines, no moving parts to maintain or repair, less leak potential and a wide flow turndown range. Vortex meters also offer very low power consumption, allowing for use in remote areas.

Additionally, Vortex meters are unique in that they can accommodate liquids, gasses, steam, and corrosive applications. Vortex flowmeters are also able to withstand high process pressures and temperatures.

Rosemount 8800 Series Vortex Flow Meters offer world-class reliability with a gasket-free, non-clog meter body that eliminates potential leak points, resulting in maximum process availability and fewer unscheduled shutdowns. The unique design of Emerson’s Rosemount 8800 Vortex Flow Meters features isolated sensors that eliminate the need to break process seals for flow and temperature sensor replacement.

What is the Vortex flow meter?

A vortex flow meter is a flow measurement device best suited for flow measurements where the introduction of moving parts presents problems. They are available in industrial grade, brass or all-plastic construction. Sensitivity to variations in the process conditions is low and no moving parts have relatively low wear compared to other types of flow meters.

Vortex flowmeters operate under the vortex shedding principle, where an oscillating vortexes occur when a fluid such as water flow past a bluff (as opposed to streamlined) body. The frequency that the vortexes are shed depends on the size and shape of the body. It is ideal for applications where low maintenance costs are important. Industrial size vortex meters are custom built and require appropriate sizing for specific applications.
