Sanitary electromagnetic flowmeters LF490 series are designed for applications handling food and beverages.
Sanitary flowmeters must be structured in such a way that operation and handling is simple, easy and thorough for the purpose of sanitary control such as cleaning (CIP/SIP), sterilization and drying.
The sanitary flowmeter has features provided with normal electromagnetic flowmeters and by using sanitary fittings for pipeline connections fluid does not remain in any place along the detector pipeline.Therefore, it is fit for flowrate measurement for food and beverages.
With the "Functional Magnetic Field Distribution" technology, LF490 is strong against unstable flow.
Combined with a multi-functional converter LF620 (Combined type) or LF622 (Separate type) equipped with its original Noise-suppression Circuit & Advanced Algorithms, The LF490 has a very high tolerance to noise, giving the unit a very stable output even for slurry fluid measurement.
The AF900 Hand-held terminal (HART(*1) Communicator) can be used for remote control. PROFIBUS-PA(*2) or Modbus(*3) interface is available as an option.
