Abstract

The invention relates to a float type liquid level gauge, which includes a float, a scale and a luminous wheel, and is characterized in that it also includes a conductive or magnetically conductive guide rail, and the luminous wheel includes an insulating box, a light source, and two horizontally arranged magnetic shafts Or a metal shaft and two wires that supply power to the light source. For a magnetic float level gauge, the luminous wheel also includes a magnet steel. Under the action of magnetic force, the magnetic shaft or metal shaft moves up and down along the guide rail as the float moves up and down. , timely and accurately realize the local indication of the liquid level; or by winding the resistance wire on the guide rail, the corresponding liquid level value can be obtained by measuring the resistance value in the conductive circuit composed of the guide rail, magnetic shaft or metal shaft, wire and light source, etc. Realize continuous remote transmission of liquid level data. Pulleys, counterweights, coupling ropes or coupling straps can also be included to balance the luminous wheels. The invention has the remarkable characteristics of simple structure, clear and eye-catching local indication, sensitive and accurate measurement, and continuous remote transmission signal.

Description

technical field

[0001] The invention relates to the field of liquid level measurement, in particular to a float type or magnetic float type liquid level gauge. . Background technique

[0002] The liquid level gauge is an instrument with a wide range of applications, and many people study the problems existing in the prior art.

[0003] Existing liquid level measuring instruments are of various types, each with its own strengths, but also have shortcomings. Based on the present invention, the existing instruments have unclear on-site indications, are difficult to observe in dark places or at night, and remote signals are not clear. Continuous, remote transmission and local indication use two sets of mechanisms, and a series of problems such as large friction affecting measurement accuracy, etc., the existing comparative technologies are described as follows:

[0004] - Existing local indicating type and / or additional float type liquid level gauge with remote transmission ...
