Description
|
ientek
of Electromagnetic Flowmeters(EMF) can be used to accurately
measure the flowrate of liquids,
paper
pulp, slurry and mineral slurry which has an electrical
conductivity greater than 5μS/cm.
EMFF
Integral Type is a flow measurement system in a compact
design which integrates the primary and
signal converter.
EMFS
Remote Type flow measurement system consists of a flowmeter
primary and a remote mounted converter.
The Faraday Laws of Induction, which state
that an induced electromotive force is generated in a
conductor when it moves through a magnetic
field, form the basis for the electromagnetic flowmeter
measurements.
This
measurement principle is applied to a conductive fluid which
flows in a pipe in which a magnetic
field is generated perpendicular to the
flow direction.
The electromotive force
which is induced in the fluid is measured at two electrodes
located diametrically
opposite to each
other.
This signal voltage UE is
proportional to the magnetic induction B, the electrode
spacing D and the
average fluid velocity
v.
Since the magnetic induction B and the
electrode spacing D are constant values the signal voltage
UE is
proportional to the average fluid
velocity v.
The equation for calculating
the volumetric flowrate shows that the signal voltage UE is
linear and
proportional to the average
fluid velocity v.
The induced signal
voltage is converted into programmable analog and digital
output signals in the converter.
