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. The electromagnetic flowmeter uses Faraday’s Law of electromagnetic induction to measure the process flow. The device consists of two units: a detector, through which the fluid to be measured flows and in which low-level signals proportional to flow rates are obtained; and a converter, which supplies excitation current to the detector, and amplifies the signals from the detector and then processes and converts the signals into the 4–20mAdc current signal. With the unique patented magnetic field distribution technology, the meter is highly immune for upstream flow disturbances. Combined with a multi-functional  converter LF620(combined type) or LF622(separate type) equipped with its original noise-suppression circuit and advanced algorithms. The LF490 has high tolerance to noise, giving stable output even for slurry fluid measurement. IR (Infrared) switches enable parameter setting of the converter without removing the cover. Flow direction can be set in either way, and its 128 x 128 dot matrix LCD display allows the LCD to be rotated electronically to 90, 180 and 270 degrees without opening the cover. The terminal block in LCD side make easy to wire in case of the combined type.
