A high performance, sterile electromagnetic flowmeter for use in a wide range of applications in the pharmaceutical and chemical industries is available from Krohne, with the launch of Variflux 6000.
Variflux 6000 features a unique L-shaped sealing ring with a unidirectional trapezoidal lip, which (unlike regular O-rings) eliminates the problem of bacteria growth by preventing expansion of the rubber seal into the measuring tube. The sealing ring was developed in close cooperation with the EHEDG (European Hygienic Engineering & Design Group), together with customers in the pharmaceutical industry.
Suitable for a broad variety of duties from ultra-precise batching to flow measurement in large-scale production plants, Variflux 6000 has a smooth measuring tube liner made from FDA-approved Teflon-PFA, which allows for easy and effective cleaning and prevents the build up of bacteria. The liner is chemically and mechanically stable and has been proven in more than 100 000 Krohne EMFs. It is CIP and SIP proof, and all wetted parts of the meter are made from FDA-approved materials. The fully welded stainless steel housing of Variflux 6000 is designed for easy cleaning and ensures high resistance to corrosive attack from aggressive cleaning agents.
All other parts of the meter in contact with the flow are also manufactured from sterile materials such as stainless steel adapters and Hastelloy C4 or stainless steel electrodes. The measuring tube liner is reinforced with a stainless steel mesh, which guarantees accurate results even under varying pressure and temperature conditions, and provides full vacuum resistance up to process temperatures of 180°C. Calibration on test rigs with less than 0,03% uncertainty contributes to the high accuracy and repeatability of the meter. Variflux 6000 meters are available in a broad range of sizes catering for flow rates from a few litres per hour to up to 750 cubic metres per hour.
