  • Measurement Of Levels Of Liquids Or Fluent Solid Materials (AREA)

Abstract

PURPOSE:To enable the measuremen of liquid levels to be started by the detection signal and achieve the simplification of mounting of the apparatus by detecting the arrival of containers being carried based on the output of the line sensor disposed on the side of the conveying line. CONSTITUTION:A photoelectric detector 3 is perpendicularly disposed so as to oppose to a projector 2 with the conveying line in-between. When this container 1 is disposed before the detecting optical axis connecting the projector 2 and photoelectric detector 3, all the outputs of the photoelectric detector 3 are above Schmitt level Vs and when the edge part of the container 1 comes on the detecting optical axis, all the outputs of the photoelectric detector 3 become below the Schmitt level Vs. Next, when the central part of the container 1 aligns to the detecting optical axis, the signals above the Schmitt level Vs appear at the beginning and change to the signal below the level Vs on the way in the outputs of the photoelectric detector. The time when the edge part of the container 1 arrived at the detecting optical axis is detected from the outputs of the photoelectric detector 3 in this way, and the measurement is started immediate after the edge part has passed, whereby whether the liquid level is within the specified range or not may be measured.
