Application
Tips: What is a sanitary flow meter and why is it used for milk or beer?
A sanitary flow meter is a specialized flow measuring device designed for hygienic applications, such as in the dairy and brewing industries. It is made with 304 or 316L stainless steel and food-grade liners (like PTFE) to ensure corrosion resistance, easy cleaning, and compliance with food safety standards. For milk and beer production, it helps monitor and control flow during pasteurization, fermentation, filtration, and filling, ensuring accurate batching and quality consistency.
