Flow Metering Technology

Electromagnetic flow meter
GEA Diessel is one of the pioneers in the field of the hygienic metering of liquids for the
food and beverage industry. It was in the mid-1980s that the company started to develop
electromagnetic metering technology based on the IZM device. Since then, this technology
has almost completely replaced mechanical meters in this market segment.
The electromagnetic unit, which operates in accordance with Faraday's Law of Induction,
has no moving parts that are liable to wear. Even liquids with low conductivity can be
measured reliably. Thanks to their precision, reliability and flexibility, these metering
devices offer a broad range of possible applications.
Decades of experience and constant further development involving the integration of new
innovative technologies have produced a series of devices that set standards for
the future.
IZML: simple, precise and economical
Practical operation demands the following features:
-precise measurement of the flow of liquids within
the production process
-simple installation and rapid commissioning
- no maintenance
- high reliability and a long service life
- economy
Simple and straightforward cleaning ensures that high-value
products can be manufactured under absolutely hygienic
conditions.
Precision, linearity and reproducibility are of course the basic
requirements for metering devices.
With its technical properties and its economic price, IZML is
in every way the ideal metering device for the foodstuffs
industry.
IZML is designed to fulfil
all these requirements
The IZML model of electromagnetic
flow meter supplies
precisely the information that
is required for the control
and regulation of processing
plant. The operator is thus
able to enhance the efficiency
of complex production
facilities at low cost.
IZMS: approved by weights and measures authorities
The IZMS model of electromagnetic flow meter fulfils almost
every requirement. It offers the most flexible technology for
the most exacting demands.
The electromagnetic metering principle has proved itself in
industry over decades. It is not affected by the density,
viscosity or temperature of the liquid. Needless to say, the
essential components are made of stainless steel.
Asmooth measuring tube, no internal fittings, no moving
parts: these are the decisive advantages of this metering
technology.

IZMS has of course been granted type approved by the
German weights and measures authorities PTB, and is thus
able to measure with extreme precision those quantities from
which the amounts payable are calculated.
This device is being used successfully for many applications
relating to milk, beer and other products.
Needless to say, IZMS devices are also made of stainless steel.
Product temperatures of up to 150° C are no problem.
IZMT/R metering systems for every conceivable
“niche” application
In addition to simply measuring flow and volume, the basic
unit of the electromagnetic flow meter can be flexibly
modified or expanded in such a way as to allow even more
complex functions to be carried out.
•Where a medium has to be pumped from one vessel to
another, the IZMS halts the process automatically when
the desired quantity has been reached
•Even very small quantities are dosed precisely at
intervals of a second
•Packaging statistics are constantly updated and can be
documented on a PC
•Quantities received or delivered are registered in
a printed document - also for official purposes
•For reception and delivery procedures, the customer
numbers and product designations are recorded together
with the metering data, are stored and printed out as
a report
•Product temperatures may be important; the IZMT
measures and documents them.
•Flow is kept constant at the desired level by the
operation of a regulating valve
•With the aid of a second meter, the IZMR is even able to
regulate precisely a pre-determined mixing proportion
•The sampling control provides a regularly distributed
sample for laboratory analysis
•The high precision DI-Master, whose accuracy has been
enhanced yet again, effects the calibration of meters that
operate by the most varied measuring principles, and
provides for “flying” measurement, so that the meters to
be calibrated do not have to be removed from
the production equipment.
Fittings such as the milk pipe as per German standard
DIN 11851, the flange and the clamp allow the device to be
installed in the product pipe in whatever way is desired.
Thanks to the precise recording of even very low flow speeds,
starting from 0.03 m/s, a very wide dynamic range is
available.
The easily detachable “MEMbox” memory module provides
for permanent saving of the calibration data.
The integrated keypad and display allow the device to be to
operated easily and reliably.
