Description
The external chamber model BZG consists of an external chamber vessel that is mounted laterally to a vessel using at least 2 process connections (flange, thread or weld stub). Through this type of arrangement, the level in the external chamber corresponds to the level in the vessel.
The level is measured by a measuring instrument inserted additionally in the external chamber, for example model FLR or FLS, or by a guided wave radar.
