Flow-VizTM – A fully integrated and commercial in-line fluid characterization system for industrial applications

A new fully integrated ultrasound based in-line fluid characterization system, Flow-VizTM, has been developed especially for opaque, non-Newtonian industrial fluids. The new embedded and commercially available system is designed to meet industrial requirements. Flow-VizTM enables true non-invasive, real-time Doppler measurements and is able to visualize the flow and to rheologically characterize industrial fluids continuously while providing continuous feedback to an existing process control system for enhanced efficiency. The Flow-VizTM system consists of an operator’s panel, a multitouch monitor and an industrial PC unit and pulser-receiver electronics. The electronics has been improved and extended by adding a second ultrasound channel, augmenting the on-board data processing for obtaining the optimal performances in high attenuating suspensions. A new Motherboard provides an additional 8-channel digital and analog input and output capabilities for simultaneous data acquisition and connection to a process control system. The new electronics is combined with a non-invasive ultrasound sensor unit, which allows measuring the flow velocity profile even through industrial high grade stainless steel pipes. This unique solution makes possible to adapt the high resolution UVP+PD technique for industrial processes performed at high temperatures and/or pressures using a wide range of different industrial fluids. The Flow-VizTM system is already installed in industry, e.g. for chocolate and grouting applications and an international patent has been filed.
