Potential ruler continuous material level measurement system and measurement method thereof

Abstract

The invention discloses a potential ruler continuous material level measurement system free of adjustment, applicable to realtime measurement of material levels of various materials and high in measurement accuracy and a measurement method thereof. The potential ruler continuous material level measurement system comprises a conductive measurement rod (1) arranged in a metal container, wherein high-frequency voltages are applied to two ends of the measurement rod (1), a voltmeter (2) is connected between the bottom end of the measurement rod (1) and the metal container, and the periphery of the voltmeter (2) is electrically connected with a signal collecting module (3), a signal processing module (4), a central processing unit (CPU) (5), an analog-digital converter (6) and an analog quantity output module (7). When the materials make contact with the measurement rod (1), the signal collecting module (3) collects a voltage signal generated between the measurement rod (1) and the metal container, the voltage signal is subjected to calculation, voltage stabilizing and amplifying, and then the voltage signal is converted into a digital signal to be output by the analog quantity output module (7). The potential ruler continuous material level measurement system can be applied to the field of material level measurement.

Description

technical field [0001] The invention relates to a potentiometer continuous material level measurement system and a method for continuously measuring material level using the system. Background technique [0002] With the rapid development of my country's economy, the industry has also developed rapidly. As a key physical quantity in industrial process control, material level measurement is more and more widely used in the industrial field. Therefore, the demand for material level gauges in the industrial market It is also getting bigger and bigger, and the technical requirements for level gauges are getting higher and higher. However, my country's technology is basically based on foreign technology, and there is a big gap with foreign countries in key areas such as practicality and technology. Although the material level gauges in foreign markets are relatively advanced in technology, they cannot get rid of the shortcomings of each material level measurement method of the ma...

AI Technical Summary

Problems solved by technology

[0006] Heavy hammer: It is greatly affected by the physical and chemical properties of the measured medium, and the steel cable has risks such as easy jamming and fracture

[0007] Ultrasonic: only suitable for smooth and flat materials such as liquids, not suitable for materials such as solids, dust particles and steam that will diffuse

[0008] Float: only suitable for general liquids, not solid or sewage (sewage will affect the flexibility of the float) and other occasions

[0009] Weighing: Vulnerable to pipe installation and difficult to use in kiloton tanks
