Float Level Switch · Cargo Level & Temperature Gauging
Krohne BM70A 10m Ex ia Marine is a float level switch. It is installed on or in a cargo tank and connected to the cargo-monitoring or alarm system. Its purpose is to detect a defined liquid level or provide a discrete tank-level alarm or control signal. The sensing element, float mechanism, switch, process connection and hazardous-area interface depend on the exact model and cargo service. The exact model designation distinguishes process connection, material, switch arrangement and approval from neighboring level devices; refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect accessible housing, process connection, cable glands and junction boxes for leakage, corrosion and damage. Function-test the level switch using an approved simulation or tank-level method and confirm the correct alarm or control channel responds. Clean deposits from moving elements only using procedures compatible with the cargo and detector materials. Verify hazardous-area integrity and restore covers and glands correctly after electrical work. Compare installation position with approved tank drawings after replacement. Refer to the manufacturer documentation for the exact figure for test method, material compatibility and switching limits.
Keep model-correct float or switch elements where serviceable, seals, gaskets, cable glands, junction-box parts and approved interface modules. Replacement devices must preserve hazardous-area approval and process-material compatibility. Confirm switching logic before installation.
