Abstract

The invention relates to a liquid storage tank material level indicating device with signal long-distance transmission as well as a design method and material level calculating method of the indicating device, and belongs to the field of liquid material level detection. The indicating device lies in that a soft rope A is connected with a floater and a driving pulley of a double-wheel pulley; a soft rope B is connected with a driven pulley of the double-wheel pulley and a counterbalance weight body, and the middle of the soft rope B is connected onto a fixed pulley in a bridging manner; the driving pulley and the driven pulley of the double-wheel pulley are all fixed on the same pulley spindle; the pulley spindle is mounted on two bearings; one end of the pulley spindle is connected with a potentiometer shaft sleeve through a shaft coupling tube; the potentiometer shaft sleeve is connected with a potentiometer; the shaft coupling tube is in movable connection with the potentiometer shaft sleeve; the middle of a soft rope C is hung on a reversing fixed pulley, and the two ends of the soft rope C are respectively connected with the counterbalance weight body and an indicating light bar; the indicating light bar can move up and down along a scaleplate; the power source of the indicating light bar is controlled by an optoelectronic switch and the indicating light bar is supplied with power through a flexible circuit conductor. According to the liquid storage tank material level indicating device with signal long-distance transmission as well as the design method and material level calculating method of the indicating device, provided by the invention, liquid level of liquid in a liquid storage tank can be observed directly without needing labors to climb up the liquid storage tank, liquid level observation is not influenced by power failure, and a resistive signal which has a linear relationship with the liquid level is provided.

Description

technical field [0001] The invention relates to a liquid storage tank material level indicating device with signal remote transmission, a design method thereof, and a material level calculation method, belonging to the field of liquid material level detection. Background technique [0002] In-situ liquid level indication and signal remote transmission of liquid storage tanks are commonly used detection technologies in industrial processes. There are many types of liquid level detection instruments and detection methods, each with its own strengths, and different technical methods are used to solve the detection of liquid level. problems, but there are also some shortcomings. [0003] Radar level gauges, ultrasonic level gauges, laser level gauges and other level detection instruments can be directly installed on the liquid storage tank to measure the liquid level, but they are not suitable for highly corrosive liquids, high pressure, high temperature, foggy, easy to condense...
