Piezoelectric intelligent solution depth measuring device and measuring method

Abstract

The invention discloses a piezoelectric intelligent solution depth measuring device and a measuring method. The piezoelectric intelligent solution depth measuring device comprises a floater, a lower shell, a connecting pipe and a fixed frame; the lower end of the floater is connected with the upper end of the lower shell through the connecting pipe; the lower shell is connected with the fixed frame; the floater is arranged inside the fixed frame; and the floater and the lower shell are both closed bodies, and the whole device can sink in a solution. A piezoelectric ceramic force measuring mechanism is disposed inside the floater and the lower shell respectively; a battery and a data processor are also disposed inside the lower shell; and the piezoelectric ceramic force measuring mechanismand the battery are both electrically connected with the data processor. According to the piezoelectric intelligent solution depth measuring device provided by the invention, the depth and density ofthe solution are obtained by obtaining the buoyancy borne by the floater and the pressure of a corrugated sealing element on the floater, and the depth and the density of the solution are output through the data processor; and besides, the device is simple in structure, easy to manufacture and low in manufacturing difficulty, is suitable for measuring various liquid media, and overcomes the defects caused by an existing measuring method.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a piezoelectric intelligent solution depth measuring device and a measuring method. Background technique [0002] In order to monitor the liquid level to be measured in rivers, lakes and seas, as well as the liquid level in the production and application of chemical industry and other industries, at present, the widely used measurement methods are direct measurement, ultrasonic, far-infrared, conductivity and conversion by pressure sensor installed in the liquid. Measurement and other methods, although these methods are convenient and quick, but the installation and use places are relatively limited, especially when the solution density changes greatly, the accuracy is difficult to guarantee. [0003] Direct transparent tube or conductivity method measurement, the liquid level is accurate, but the application occasions are limited, and the solution density cannot be obt...

Problems solved by technology

However, if it is necessary to measure the depth of a river, this method is difficult to measure, and it cannot be monitored remotely; the online liquid depth measurement device is realized by a liquid depth sensor installed in the container, but the solution density needs to be obtained in advance. When the solution density changes, The measured depth error is relatively large, and multi-point sensors are also used, but their installation is limited
