Application
Electromagnetic flowmeters are suitable for measuring the flow
of almost all electrically conducting liquids, as well as sludges,
pastes and slurries.
A prerequisite is that the medium must have a certain minimum
conductivity. The temperature, pressure, viscosity and density
have no influence on the result.
This special design of an electromagnetic flowmeter (MID) is
particularly suitable for measuring the flow of extremely small
quantities and especially for use with proportioning and batching
systems. In conjunction with the transmitters Intermag
2/Transmag 2, complex tasks can be solved using the integral
software for batching applications. Typical applications can be
found in the food industry, the dosing of chemicals in
photographic systems, and the dosing of medicines in medical
fields.
When using the alternating field technique with the transmitter
Transmag 2, even very small flows can be exactly measured as a
result of the larger magnetic field and the zero stability.
The flow sensors
mag-flux
F5 are used mainly in the following
industries:
·
Water and waste water plants
·
Chemical and pharmaceutical industry
·
Food- and beverage industry
·
Mining, cement and mineral materials
·
Pulp- and paper industry
·
Steel industry
·
Power generation and distribution.
The flow sensor are combined with the transmitters Intermag
2/Transmag 2 and are only available as remote versions.

Note of application
·
The operator of these measuring instruments is responsible for
suitability, proper use and corrosion resistance of the used
materials with regard to the measuring material. It must be
ensured that the materials selected for the meter parts in
contact with the medium are suitable for the used process
media.
·
Before replacing the measuring tubes, check that the meter is
free of hazardous media and is not pressurized.
·
The unit may only be used within the pressure and voltage
limits specified on the rating plate.
·
The flowmeter complies with the requirements of the Pressure
Equipment Directive 97/23/EC, article 3, paragraph 3. The
most hazardous permissible media are the fluids defined in
group 1.
·
Provide a touch guard for surface temperatures of > 70°C.
This touch guard must be designed in a way that the max.
allowable ambient temperature on the unit is not exceeded.
·
The sensor must not be affected by external loads.
·
The units are designed for predominantly recumbent load.
