FLOAT TYPE LIQUID SURFACE LEVEL DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a float type liquid surface level detector which hardly brings about a chattering phenomenon even in the case of the occurrence of rippling on a liquid surface of and has a simple structure to be superior in terms of a manufacturing cost.;SOLUTION: In the float type liquid surface level detector, a magnet float having a magnetic property is inserted so as to move vertically along an outer periphery of a substantially perpendicularly installed stem, and the change in a liquid surface level of a target detection liquid is detected by the change in the position of the magnet float. The flow type liquid surface level detector includes a cover member which is provided to cover the magnet float and forms a space for liquid surface detection, a liquid inlet is formed in a lower end-side part of the cover member, an air outlet is formed in an upper surface part of the cover member, and the air outlet is provided with a valve mechanism for discharging air in one direction from the inside of the cover member to the outside.;COPYRIGHT: (C)2014,JPO&INPIT
