How it is selected & specified.
Magnetostrictive interface transmitters are not universal; they work only when the two liquids have enough density difference for stable float separation.
WELK asks for upper/lower medium, density, interface thickness, emulsion behavior, temperature, pressure and required output before quotation.
Magnetostrictive Interface Level Transmitter is presented as a configurable WELK product family. Final model limits, wetted materials, process connection, certificate and output signal are confirmed from the selected datasheet before quotation.
Magnetic and local gauge selection depends on center-to-center distance, density, pressure, temperature, flange standard, chamber material, visibility requirement and whether switches or a transmitter are needed.
Interface measurement requires two liquids with enough density separation and a stable interface layer.
