Descripción
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 flow rate 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 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
LF490 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 terminal block in LCD side
make easy to wire in case of the combined type.
