Magnetic Inductive Flowmeter Model EPS

Description

The EPS magnetic-inductive flow sensor is used to measure
the volumetric flow of liquids, slurries, pastes and other
electrically conductive media without any pressure drop.
Pressure, temperature, density and viscosity do not affect
the volume measurements. Solid particles and small gas
bubbles should be avoided. The EPS sensor can be used
in combination with the KOBOLD UMF2 transmitter. The
transmitter is available in a compact version or a remote
version.

Operation

An electrically conductive media flowing through a magnetic
field, in accordance to Faraday's law of induction, will induce
a voltage proportional to the mean flow velocity rate and
hence the volumetric flow. A magnetic inductive flowmeter
consists of a lined flow body, through which a conductive
liquid flows, a magnetic field coil and two electrodes. The
electrode voltage is detected by a transmitter and converted
into standardized electrical signal such as 4-20 mA or pulse
output.

Advantages

Ambient Conditions

As the flowmeter becomes an element of the piping, they are
sometimes thermally insulated when installed to save energy
and prevent accidental physical contact. The heat of the process
temperature will be transferred through the support neck of the
integrally mounted transmitter or terminal box. For this reason the

thermal insulation of the flowmeter should only extend half way
up the support of the transmitter. It is essential not to include the
transmitter or the terminal box as part of the thermal insulation.
The maximum permissible liquid temperature limits are stated on
the rating plate of the respective flowmeter version.
