Automatic calibration liquid level detection device

Abstract

The invention discloses a liquid level detection device with an automatic calibration function. The device comprises a detection device body, wherein the left side of the detection device body is fixedly provided with an installation mechanism, and the inner side of the installation mechanism is provided with a limiting mechanism installed in a container shell; the limiting mechanism comprises a mounting frame and a mounting rod, and the mounting rod is mounted in the inner side of the mounting frame; a connection mounting column, which is arranged on the inner side of the lower end of the detection device body, a tilt angle sensor arranged in the detection device body is mounted at the left end of the connection mounting column, and a limiting plate fixed to the lower side of the detection device body is arranged on the outer side of the connection mounting column, and an ultrasonic liquid level meter fixed to the right side of the limiting plate is arranged on the right side of the limiting plate. According to the liquid level detection device with the automatic calibration function, automatic calibration can be carried out, the situation that the detection accuracy is affected due to loss of measurement standards is avoided, and certain limiting protection can be carried out on the transmission cable according to containers with different depths so that abrasion consumption of the outer side of the cable can be reduced.

Description

technical field [0001] The invention relates to the technical field related to liquid level detection, in particular to an automatic calibration liquid level detection device. Background technique [0002] Liquid level detection is a widely used technical means. Liquid level detection technology is used in chemical, pharmaceutical, biological, transportation and other industries to monitor liquid inventory, so as to ensure the normal operation of related systems. At the same time, in scientific research or medical instruments, a large number of testing items need to introduce liquid reagents or pure water, and waste liquid will be collected, so the instrument system needs to monitor the liquid stock used and remind users. [0003] The Chinese patent authorization publication number is CN109186687B, a kind of salt pool concentration and liquid level detection device set, including: concentration detection device and liquid level detection device The concentration detection de...
