Flowmeter offers greater functionality
Bürkert has released the latest update to its FLOWave flowmeter, which offers greater functionality and widens its appeal for the pharmaceutical sector as well as food and beverage applications. The list of new capabilities includes the ability to detect different fluids, which will open-up new applications in many areas.
In very simple terms, the Type 8098 FLOWave uses a smooth stainless-steel tube, and surface acoustic wave (SAW) technology to measure fluid flow very accurately. It has already demonstrated many advantages in hygienic/water applications and the scope is now set to increase significantly with the latest model release.
The introduction of the density factor and acoustic transmission factor have helped improve accuracy for a wider range of fluids, as well as the detection of bubbles and solids. The density factor compensates for the change in the speed of sound at different temperatures. This enables FLOWave to detect a change of liquid in a running process, for example when a clean-in-place (CIP) process ends and normal production is resumed. Similarly, it can also detect the changeover point between two products and provide this information to the supervisory system. The acoustic transmission factor (ATF) allows FLOWave to detect bubbles or solids in the liquid and display this information as a percentage, which can be used by the process management system to take the appropriate action, depending on the level of inclusion.
The ATF can also detect pipe fouling over a period of time. Provided the same liquid is being transferred, trend analysis of the flow data over an extended period will highlight any issues with pipe fouling, or a reduction in pipe diameter that is causing reduced flow, increased pressure and lost performance.
FLOWave offers the opportunity to constantly monitor flow rates and total volumes to ensure process quality and uniformity.
