Problems solved by technology
[0003] As the ultrasonic sensor operates for a long time, the ultrasonic signal will attenuate accordingly, and the processing method of the traditional technology is to amplify the ultrasonic signal with a fixed gain. When the ultrasonic signal attenuates, the corresponding acquisition effect cannot be achieved. So that the replacement of new sensors will increase the cost of the project. Therefore, we need to develop a signal acquisition method with automatic gain adjustment function to replace this traditional acquisition scheme

The invention discloses a reagent quantifying device for water quality online monitoring equipment. The reagent quantifying device comprises a quantifying tube, an ultrasonic sensor and a circuit equipment unit. Compared with the prior art, the reagent quantifying device has the advantages that the ultrasonic sensor adopts a high-frequency ultrasonic sensor with the transmission beam angle being 12 degrees, liquid quantity measuring error is controlled to be within + / -0.015ml, the quantifying tube adopts high-transparency quartz glass, the liquid level condition in the tube can be observed inreal time through a rectangular through hole in a protective cover during quantifying, and the quartz glass tube is resistant to strong acid corrosion and high temperature and can satisfy the use conditions of different reagents; the inner wall of the quantifying tube is smooth, so that phenomena such as liquid attaching and accumulation can be avoided effectively; the diameter of the quantifyingtube can be customized and flexibly regulated according to the required quantity of reagents; by a temperature measuring unit, influence of temperature on measuring distance can be compensated to increase liquid level measuring precision; in addition, the high-frequency ultrasonic sensor is made of materials resistant to strong acid and strong base corrosion, the problem that the sensor is corroded after long-term use can be solved, and the work stability of the sensor is guaranteed.
Description
technical field [0001] The invention relates to the field of high-frequency ultrasonic distance measurement, in particular to a reagent quantification device for water quality online monitoring equipment based on high-frequency ultrasonic waves. Background technique [0002] In industry, it is often necessary to quantify the height of liquids, such as the quantification of various chemical reagents. The quantification of these reagents requires more accurate measurement tools. Since the height and width of the quantitative tube used in the quantitative system are within a small range, there are nearly Due to the problem of the distance blind zone, it is necessary to develop a liquid volume quantification device with a small blind zone and a small launch angle, which can accurately quantify the height of the solution in the tube and reduce the measurement error. [0003] As the ultrasonic sensor operates for a long time, the ultrasonic signal will attenuate accordingly, and t...
