Abstract

The invention provides an automatic digital water level control warner. The automatic digital water level control warner comprises a sensor and a display instrument; the sensor comprises a shell and a detection circuit board arranged in the shell; two groups of wire connecting terminals a and b, and c and d are arranged on the detection circuit board; the two ends a and b are connected with the two ends e and f of the display instrument respectively through two lead wires; the end c of the detection circuit board is connected with one end of a sensing test line L; the other end of the sensing test line L is vertically placed in water; the end d of the detection circuit board is connected with one end of a grounding probe T; the other end of the grounding probe T is connected with a container for containing water in a grounding way; the display instrument comprises a house and a circuit board arranged in the house; and a preposed amplifying unit, a counting unit, a driving executing unit, a 24V wire connecting end, the two ends e and f connected with two lines of the sensor in a transmission way, high-level warning output ends p and q, low-level warning output ends m and n, and external water pump control ends x, y and z are arranged on the circuit board. The automatic digital water level control warner has a scientific design, an optical practical effect, stable and reliable performance, and good development prospect.

Description

technical field [0001] The invention relates to a water level control device, in particular to a digital display water level automatic control alarm instrument which controls the height of the water level by utilizing the change of the capacitance of the meter, and is simple to install and convenient to adjust. Background technique [0002] The height of the water level can be seen around people's lives. Therefore, people have been measuring and controlling the water level for a long time. At present, there are many ways to measure the water level. In principle, it is generally laser detection, infrared test, and pressure detection. , capacitance detection method and so on. The reason why there are so many detection methods is because each method has more or less shortcomings and deficiencies, which can be summarized as follows: [0003] 1. The structure is complex and installation is inconvenient; the structure of measuring instruments with high precision is usually very c...

AI Technical Summary

Problems solved by technology

[0003] 1. The structure is complex and inconvenient to install; usually the structure of measuring instruments with high precision is very complicated from principle to production, especially the installation needs to be more cautious, and sometimes it is necessary to ensure absolute horizontal or vertical

The cost is naturally high, and the amount of maintenance is also large

[0004] 2. The measurement accuracy is different; at present, the accuracy of the water level measuring instruments used in on-site inspections can reach 0.1 or 0.2, and the low accuracy can reach 1 or 1.5. Such as instrument selection, daily maintenance, cost expenditure, etc., will bring unnecessary troubles to users

[0005] 3. The stability and reliability are uneven; usually, during the long-term use of water level detection equipment with low precision, the detection data of uplink and downlink are not uniform, the variation is large, and the reliability is poor

[0006] At present, there is a lack of water level detectors that are suitable for on-site use, easy to install, simple to adjust, stable in performance, and cost-effective.
