External Chambers are used for mounting the range of process level instruments to a vessel. Externally mounting an instrument in a chamber means it can be isolated for routine maintenance while keeping the plant operational. It is also useful for in-tank restrictions that do not allow mounting of the instrument in a vessel. Optimized for use with Guided Wave Radar, Hydrostatic, Float based and Magnetostrictive Level Transmitters, Displacer Level Switches and Transmitters, Vertical Float Level Switches, Horizontal Float Level Switches
