Bürkert FLOWave SAW Flowmeter

The Type 8098 flowmeter is part of the FLOWave product range. It is based on SAW (Surface Acoustic Waves) technology and is mainly designed for applications with the highest hygienic demands. This is achieved by using suitable stainless steel materials, a measuring tube completely free of any internal parts and an ideal outer hygienic design. FLOWave offers a range of integrated functions including the advantages of flexibility, ease of cleaning, compact dimensions, lightweight, easy installation and handling, and is compliant with numerous standards. Optimal measurement results can be achieved with homogeneous liquids, free of air and solid particles. For liquids with high viscosity, an integrated viscosity compensation can be activated. Gas and steam cannot be measured. However, their flow has no effect on the proper functioning of the device. Liquids that subsequently flow through the measuring tube again continue to be measured correctly. Beside volume flow, a density measurement optional feature is available. With this option, the mass flow is calculated based on volume flow and density measurements. Special functions derived from further process values (differentiation factor (DF), acoustic transmission factor and concentration) offer additional information about the particular liquid in use (for details, see data sheet).
