Magnetic inductive flow rate measurement*
The magnetically inductive flow measurement presented uses a permanent magnetic field as opposed to an alternating magnetic field. In conjunction with the capacitive signal decoupling, this new technology allows for an extremely compact sensor design coupled with minimal energy consumption, such that mains-independent operation is possible. Nevertheless, all the known advantages of MIF are retained: smooth inner tube without additional pressure drop, measurements irrespective of the temperature, viscosity, pressure, density and largely regardless of the flow profile. Compared with conventional MIF, the use of state-of-the-art magnetic materials made from inter-metallic compounds with elements from the group of rare earths permits magnetic fields that are higher by one order of magnitude. This directly benefits the measuring accuracy.
The possible fields of application are diverse. The new technology is suitable for all applications where low power consumption and a compact design are significant factors. Furthermore, the technology taps into entirely new fields of application in Microsystems technology that were inaccessible for previous magnetically-inductive solutions.
