DEVICE FOR DETERMINATION OF LIQUID LEVEL IN HERMETIC RESERVOIRS Russian patent published in 1997 - IPC

Abstract RU 2084837 C1

FIELD: instrumentation engineering; devices for measuring level of liquid in reservoirs. SUBSTANCE: device has receiving and transmitting light conduits enclosed in cylindrical hollow housing inside which piston is mounted for vertical motion. Piston is provided with corner reflector fitted on its surface. Input and output of radiation are interconnected by means of optical closing device made in the form of disc with ports whose outer surface is coated with reflecting layer. Output of photodetector is connected with input of one-shot multivibrator whose output is connected with input of radiation source amplifier and input of frequency meter whose output is connected with input of computer. EFFECT: enhanced accuracy of determination. 2 cl
