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 4–20mAdc current signal

or

communication signal. Thanks to the unique patented

magnetic field distribution technology, the meter is

highly immune for upstream flow disturbances.

Combined with multi-functional converter LF600

(combined type) or LF602 (separate type) equipped

with its original noise-suppression circuit and

arithmetic operation capability, LF410 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

rotated to 90, 180 and 270 degrees with a software.
The AF900 hand-held terminal (HART*

1

communicator) can be used to communicate with the

flowmeter from a remote place. PROFIBUS-PA*

2

interface is available as option.

*1: HART protocol (Highway Addressable Remote

Transducer) is a communication protocol for industrial

sensors recommended by the HCF

(HART

Communication

Foundation).

*2: PROFIBUS is the communication protocol for the

factory automation and process automation that

PROFIBUS Organization recommends. Instead of

analog control with a conventional analog signal

(4-20mA), it is one kind of the fieldbus which digitized

all signals. Flowmeters support PROFIBUS-PA.
