Title: RADIOACTIVE SELECTOR CIRCUIT FOR CONTROLLING THE LEVEL OF MATERIAL BETWEEN A SOURCE AND SELECTOR

Patent ·
OSTI ID:4016809

A control device is designed for the maintenance of the level of fluent materials in a container. The device comprises a radiation source, a Geiger- Mueller tube, a blocking oscillator-type circuit to be triggered by the Geiger- Mueller pulses, and means for energizing an indicator or control circuit in accordance with the oscillator output. The radiation source and Geiger-Mueller tube are located so that the radiation beam is attenuated by the fluent material when it is at the proper level. (D.L.C.)
