Water volume detection system for dynamic liquid level

Abstract

The invention discloses a water volume detection system for dynamic liquid levels. The water volume detection system comprises two sets of liquid level detection devices which are connected in parallel and a data processing module, the liquid level detection device comprises a liquid level sensor and a detection circuit module; the liquid level sensor measures the change of the water level of the water storage tank through the height change of the floating ball and outputs a current signal; the detection circuit module is used for converting a current signal which is output by the liquid level sensor and reflects the height of the liquid level into a voltage signal and accessing the voltage signal into the data processing module; the data processing module carries out AD sampling on the voltage signals output by the two sets of detection circuit modules and calculates the water volume of the water storage tank according to a preset algorithm. According to the invention, the water volume of the water storage tank under the dynamic liquid level condition can be accurately obtained in real time.

Description

technical field [0001] The invention relates to the field of dynamic liquid level detection, in particular to a water volume detection system for dynamic liquid level. Background technique [0002] Commonly used liquid level detection methods are: 1. Pressure type liquid level measurement. According to the principle of hydrostatics, the difference between the static pressure of a point in a static medium and the pressure of the free space above the medium is proportional to the height of the medium above the point, so the liquid level can be measured by differential pressure. 2. Buoyancy type liquid level measurement. Using the principle of buoyancy, the liquid level is measured according to the change of the position of the float with the liquid level, or the change of the buoyancy of the float partially immersed in the liquid with the liquid level. 3. Electrical liquid level measurement. The sensitive element is made into electrodes of a certain shape and placed in the ...

Problems solved by technology

[0003] At present, the water volume collection mainly adopts the single liquid level sensor detection system, which cannot effectively detect the water volume for the dynamic change of the liquid level, and the collected water volume is inaccurate, resulting in inaccurate water volume control.
