Product > Model FFM62 Electromagnetic
Flowmeter
FFM62 intelligentized electromagnetic flowmeter is
a stable and precise flowmeter which is developed on the basis of
Faraday law of electromagnetic induction and weighted function magnetic
field distribution technology. The low-frequency rectangular wave
excitation and intelligentized transformation technology are adopted
to ensure the stable zero and precision of 0.5 grade and repeatability
of 0.25%. The flowmeter is applicable to the flow measurement of
the conducting liquid and fluid (such as pure water, sewage, all
kinds of acidic, basic and salt solutions, slurry, pulp, paper pulp
and liquid for food)inside the closed pipes. It is widely applied
to the industries including metallurgy, paper making, water treatment,
chemical processing, light industry, textile, power and mining.
technical advantages of FFM62 intelligentized
electromagnetic flowmeter£º
Intelligentized transducer
adopts the internationally advanced MCU and SMT technology. It
is reliable in performance, high in precision, low in power consumption,
stable in zero, and convenient for parameter setting. The Chinese
LCD in the form of lattice is provided.
The high-precision constant
current source low-frequency rectangular wave excitation is adopted
to ensure the stable magnetic field. It is free from the electromagnetic
interference. No vortex effect is generated and the orthogonal
and in-phase interference are small. In addition, no polarization
will occur. These characteristics will ensure the low power consumption
of flowmeter. No heat is generated and the zero is quite stable.
No drift will happen and the little pollution will happen to the
electrode.
Intelligentized transducer
adopts clutter suppression technology to eliminate the clutter
completely to ensure the stable measurement. In order to ensure
the accurateness in measurement, the function magnetic field analysis
is adopted to remove bias flow. These techniques help overcome
the interferences of noises from the fluids such as slurry and
paper pulp to ensure the stability and accurateness in measurement.
It is the greatest advantage of Floworld FFM 62 intelligentized
electromagnetic flowmeter.
The electrode lead of
the sensor is led out while being kept parallel to magnetic line
of force. In this way, the induction current in the circuit of
the electrode lead of most electromagnetic flowmeters is removed;
the oxthogonal interference and zero drift that result from the
unparallelism between the electrode lead and magnetic line of
force are overcome to ensure the linearity and precision of the
sensor.
Excitation coil adopts
the advanced NC coil winding machine. The coils are automatically
controlled through the use of PLC. For the already wound excitation
coil, it will be treated with special technology to ensure the
constant and uniform magnetic field as well as the repeatability
and interchangeability of the sensor, thus ensuring the good precision,
linearity and repeatability of the sensor.

Application of FFM 62 intelligentized electromagnetic
flowmeter£º
The flowmeter is applied
to the measurement on any component in motion and disturbance,
which is free from blockage and damage due to the pressing and
is resistant against wear and tear.
The measurement is not
affected by the variation in other physical factors, to be more
specific, fluid density, temperature, pressure, viscosity, Reynolds
number and certain conductivity.
The actual flow can be
marked by water alone as the medium for test. Without any additional
modification, the flow of any other conducting medium can be measured.
The measuring pipe shall not come into contact with the medium.
Different lining and electrode material can be selected for measuring
the flow of the corrosive conducting medium. There is less rigid
requirement on the straight pipe of the flowmeter in the front
and the rear: 5D in the front and 3 D in the rear (D: interior
diameter of the pipe)
