TOSHIBA Field Intelligent Device Mount Anywhere Series Flanged Electromagnetic Flowmeter LF654 LF620 LF654 LF622 1 2 to 18 15 to 450 mm Introduction 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 20 mAdc current signal or communication signal The meter features a Mount Anywhere magnetic field distribution technology the meter is highly immune to upstream flow disturbances Combined with a multi functional converter LF620 combined type or LF622 separate type equipped with its patented Noise Sentry original noise suppression circuit and advanced algorithms The LF654 has a very high tolerance to noise giving the unit a very 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 unique 128 x 128 dot matrix LCD display allows the LCD to be rotated electronically to 90 180 and 270 degrees without opening the cover HART protocol Highway Addressable Remote Transducer is a communication protoc
