Problems solved by technology

[0003] At present, the top sealing assembly and the top of the positive and negative tubes are generally fixedly connected by welding or extrusion. If there are impurities at the bottom during use, coupled with the edge effect of the capacitor, the capacitive liquid level will be reduced. The measurement value of the meter is abnormal

Abstract

The invention discloses a single-capacitance type liquid level meter. The device comprises an anode tube, a cathode tube, a top sealing and positioning assembly and a bottom sealing and positioning assembly; the top sealing and positioning assembly comprises a top sealing and positioning plug, a first sealing ring and a second sealing ring; the top sealing positioning plug comprises a first mounting column and a second mounting column; the first mounting column is sleeved with the top of the cathode tube, the first sealing ring is located between the cathode tube and the first mounting column,the second mounting column is sleeved with the top of the anode tube, and the second sealing ring is located between the anode tube and the second mounting column; and the bottom sealing and positioning assembly comprises a bottom sealing and positioning plug, a positioning seat and a third sealing ring, the bottom sealing and positioning plug is mounted at the bottom of the anode tube, the thirdsealing ring is positioned between the anode tube and the bottom sealing and positioning plug, and the positioning seat sleeves the bottom of the cathode tube. The single-capacitance type liquid level meter has the advantages of being convenient to assemble, capable of meeting the concentricity requirement for the anode tube and the cathode tube, high in measurement precision and low in cost.

Description

technical field [0001] The invention relates to the structural technical field of a capacitive liquid level gauge, in particular to a single capacitive liquid level gauge. Background technique [0002] The capacitive liquid level gauge in the prior art includes a positive tube and a negative tube, the positive tube is passed through the negative tube, and the positive tube and the negative tube are positioned at the top through the top sealing assembly, so that the positive tube and the negative tube are arranged at intervals, and the positive tube and the The bottom of the negative tube is not positioned, and the length of the bottom of the positive tube and the negative tube is the same. A liquid medium with a height of H is filled between the positive tube and the negative tube, and the capacitance of the capacitive liquid level gauge will increase with the height of the liquid level H. change with change. [0003] At present, the top sealing assembly and the top of the ...
