Promag 53 Electromagnetic Flowmeter
Promag measuring instruments are electromagnetic flowmeters for bidirectional
measurement of liquids. They provide cost-effective flow measurement with a
high degree of accuracy for a wide range of process conditions.
The tried-and-tested Promag sensor offers the following:
• No pressure loss
• No sensitivity to vibrations
• Simple installation and commissioning
Faraday's law of induction states that a voltage is induced in a conductor moving
in a magnetic field. In electromagnetic measuring, the flowing medium
corresponds to the moving conductor. The induced voltage is proportional to the
flow velocity and is detected by two measuring electrodes and transmitted to the
amplifier. Flow volume is computed on the basis of the pipe's diameter. The
constant magnetic field is generated by a switched direct current of alternating
polarity.
