Alfa Laval Wine makers around Europe can drink a toast to the clear advantages of reliability and low maintenance offered by Krohne’s H250 flowmeter which plays a key role in centrifuges used to clarify their wine. Alfa Laval, the world’s largest supplier of separation solutions, is using H250 flowmeters in a range of solids-ejecting centrifuge modules. The centrifuge modules, manufactured at Alfa Laval’s plant in Tumba, Sweden, are particularly popular in beverage applications, and are employed by wine producers and fruit juice manufacturers around the globe for separating liquids and removing solids. All the wetted parts in stainless steel or Hastelloy. Each module is equipped with a timer triggered solids discharge, and is used to suspend solids with particle sizes from approximately 0.5 to 500 microns. Krohne’s H250 plays a crucial role within each module. Flanged to the vertical inlet pipe, the H250 accurately records the flow of liquid entering the centrifuge. If the flow is too rapid the separation of the liquid could prove ineffective. By providing the machine operator with an accurate recording of the flow rate, the settings of the centrifuge can be adjusted accordingly.
The H250 is suitable for process gas or liquid temperatures up to 200C as standard (300C with HT adaptor), standard pressure ratings of 16 or 40bar, and flow rates from 25 to 100,000 litre/h water, or 0.7 to 600mü air, 10:1. The ESK transmitters for the H250 are all Hart smart and can be supplied with a Profibus PA interface, enabling easy integration into sophisticated digital process control systems.
