Magnetic-inductive flow meters are used to precisely measure conductive liquids. The measuring principle is based on Faraday's law of induction. According to this law, a conductive liquid can be measured by its voltage as it passes through a magnetic field. The advantage of magnetic-inductive flow meters is that they work even in the absence of power supply and can be used regardless of pressure, temperature, density, viscosity and aggressiveness of the measured substances.
Magnetic-inductive flow meters are used wherever media flow, for example in the field of water and wastewater. However, media with solid components, such as sludge and concrete, or aggressive media can also be measured precisely. Areas of application include earthquake devices, fire protection devices, refrigeration technology, civil engineering, mining or in the process industry. WIKA signal converters, e.g. type FLC-608, are attached to magnetic-inductive flow meters in separate or compact configuration. This generates, for example, current for the solenoid coil and manages the communication to external control systems
