Electromagnetic Flowmeter Model MIS

Description

The new MIS electromagnetic flowmeter was developed for
measuring and monitoring medium-sized flow of conductive
liquids in pipes. The electromagnetic measurement principle is
as follows. According to Faraday’s Law of magnetic induction,
a voltage is induced in a conductor moving through a magnetic
field. The electrically conductive measuring agent acts as the
moved conductor. The voltage induced in the measuring agent
is proportional to the flow velocity and is therefore a value for
the volumetric flow. The flowing media must have a minimum
conductivity. The induced voltage is picked up by two sensing
electrodes which are in contact with the measuring agent and sent
to the measuring amplifier. The flow rate is calculated based on the
cross sectional area of the pipe.

The measurement does not depend on the process liquid and its
properties such as density, viscosity and temperature. The two
outputs can be independently set to switch, or provide an analog
or frequency output. A batching function can also be selected,
where output 1 is set to switch as NPN / PNP / PP and output 2 is
set as the control input.
