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-Anywheremagnetic 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-Sentryoriginal 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 protocol for industrial sensors recommended by the HCF (HART Communication Foundation).

**DevComm2000 Smart Device Communicator available through TIC for performing HART device configurations on PC or laptop.

*PROFIBUS is the communications protocol for factory and process automation that the PROFIBUS Organization recommends. Instead of analog control with a conventional analog signal (4-20 mA), it is fieldbus which digitizes all signals. Flowmeters support PROFIBUS-PA.

*Modbus is the communication protocol that Modicon Inc. developed. Physical layer is RS485.
