Toshiba tic-lf414c Manuel D’Utilisation

TIC-LF414C 

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. With the unique patented Mount- Anywhere 

magnetic field distribution technology, the meter is 

highly immune to upstream flow disturbances. 

Combined with a multi-functional converter LF610 

(combined type) or LF612 (separate type) equipped 

with its patented Noise-Sentry original noise- 

suppression circuit and advanced algorithms. The 

LF410 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. 

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 an 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  factory 

and process automation that the PROFIBUS 

Organization recommends. Instead of analog control 

with a conventional analog signal (4-20mA), it is  

fieldbus which digitizes all signals. Flowmeters support 

PROFIBUS-PA.
