Utilization of a nuclear-type interface level detector/transmitter.

摘要

An apparatus and method are provided for measuring and/or controlling fluid interface levels occurring within a vessel, wherein the fluid interface levels are measured and/or controlled by the utilization of a nuclear level measurment device comprising a radiation source and a radiation detector. This nuclear measurment device is externally positioned on a generally vertical standpipe which is in fluid communication with the vessel containing the fluids whose interface level is to be measured and/or controlled. The vertical standpipe is externally positioned, in relationship to the vessel, such that the fluid interface levels within the standpipe correspond with the same levels to those within the vessel.
