Float Level Switch · Cargo Level & Temperature Gauging
Krohne BM70A 5m Ex d Marine — Cargo Level & Temperature Gauging. As a Float Level Switch, it is normally installed at a cargo tank or associated stilling arrangement with signal wiring to cargo monitoring or alarm equipment. In that role, its primary purpose is to provide a discrete or continuous indication of cargo level for operations and overfill protection according to the listed device. A float level switch provides a mechanical level-triggered signal rather than continuous radar or pressure measurement and therefore depends on free float movement and reliable electrical switching. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
