Application

Electromagnetic flow sensor mag-flux A are precision measuring devices, suitable for determining the flow rate of nearly any electrically conductive fluid, but also for substances such as sludge, pulp and paste.

Due to the magnetic field, the device can be used to measure flow rates up to 10 m/s (32.8 ft/s) and a minimum conductinity of 3 ps/cm, when using a synchronized static flield.

The entire measuring device comprises a flow sensor and a dedicated transmitter. Those can be delivered either separately or as a compact unit.

The electromagnetic flow sensors mag-flux A are applied mainly in the following indudtries :

Water and sewage plants
Chemical and pharmaceutical industry
Food and beverage industry
Mining, cement and mineral materials
Pulp and paper industry
Steel industry
Energy industry, public utilities

Mode of operation

The units work on the principle of faraday’s law induction, whereby, simply stated, the sensor converts the flow into voltage, propotional to the flow rate.

Special features

Solid welded steel design, therefore rugged and fail-safe
signal amplifier inside sensor
Inside diameter of measuring tube from 15 mm (0.591″)
pressure up to 250 bar
Liner :

hard rubber
soft rubber

Informayion for sensors with PTFE lining

The mag-flux A sensor with PTFE lining is protected using a protective disc. In order to avoid formation of a vacuum,the sensor should be installed at the lowest point of the pipeline. Do not remove or demage the bead of the lining along the flanges.

Information for sensors with soft rubber lining

Sensors with soft rubber/neoprene lining are only available from nominal diameter DN 25mm (1″).

Selection on minimal diameter

The flow depends on the flow rate and the nominal diameter DN of the flow measuring device (see system information mag-flux for magnetic inductive flow measurements).

Accessories

Sensor cable

Typically, the induced signal voltage of the measuring media can be several pV or mV. the transmitter can only process these minute signal noise-free interfering signals are avoided; these nclude: signals intefering with the power frequency, signals wich are caused by vibrations in the pipeline or in the cable run, or signal caused by strong magnetic flieds in the vicinity. In this case, sufficient shielding must be provided and, if a separate design is chosen, the signal cables must be affixed firmly.
