Details
The MAGIN-Ex® series is designed for volume flow measurement, which can be integrated with further measurements such as pressure and / or temperature. To increase the fail-safety, safety-relevant circuits are redundantly designed.
The development was based on state-of-the-art technologies, both in the field of electronics and mechanical design, with the aim of offering a modern and highly-technical measuring instrument for underground mining applications. Due to the used processor electronics, high measuring accuracies and fast reaction times, as well as in conjunction with the mechanical design, a great variety of configurations can be realized. This allows you to assemble your individual measuring device for your application. With the magnetic-inductive measuring method, no mechanical components are used for the measurement recording, so that a high failure safety against e.g. pollution in the liquid is reached. According to Faraday‘s law of induction, a voltage is induced into the medium to be measured, which moves in a magnetic field, by means of two coils.
This induced voltage behaves logarithmically to the flow rate and is fed to the electronics via two laterally arranged measuring electrodes. The flow volume is then calculated over the nominal width. The direction of flow is not relevant for these volume flowmeters.
prerequisite for this measuring principle is the use of conductive media, such as for example water or liquids with water. Oil can not be measured with the MAGIN-Ex®. There is the SMALL-Ex® ViscoFlow for use in pure oil by use of gearwheels inside.
The measuring instruments are designed for use under very rough and difficult ambient conditions and withstand very high mechanical loads due to their extremely solid construction and the stainless steel housing. They are designed for use in filled systems with liquid media.
