Magnetic-inductive flow meters are based on the Faraday principle, by which a conductor which traverses a magnetic field generates a potential oriented perpendicular to that field.
The flow tube is enclosed by two flanges and also by two coils. The magnetic field which is generated by the electric current running through the coils induces a potential difference in the electrodes that is proportional to the flow being measured.
A WIKA signal converter, either attached directly to the instrument or separated from it (e.g. model FLC-608), generates the current to supply the magnetic coil, detects the potential difference between the electrodes, processes the signal to calculate the flow and manages communication with the external control systems.
The model FLC-1100J can be used wherever low-weight, compact dimensions and high reliability are needed. The flangeless sensors are available from DN 40 to DN 150.
As a “wafer sensor”, the model FLC-1100J is installed between two flanges, which ensures a high accuracy and repeatability. The installation is possible between UNI 2223 flanges from PN 16 to PN 40 or between ANSI 150 and 300 flanges. The sensor and the flange are sealed through two O-rings which are included in the delivery.
The flow tube from PA6 with glass-fibre reinforcement offers excellent resistance to aggressive media and agricultural fertilisers.
