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

●● Wide Variety of Lining Materials

●● Electrodes in Stainless Steel, Hastelloy

®

, Tantalum,

Platinum-Iridium, Titanium

●● Large Selection of Process Connections

●● For Use in Harsh Environments
