Embodiment 1

[0038] Such as figure 1 , figure 2 , image 3As shown, a drop-in liquid measurement system includes a detection device 3 placed in the liquid to be tested 306, the detection device 3 is vertically dropped into the bottom of the liquid to be tested 306, the detection device 3 is used to process the data in the detection device 3 and The wireless transmitting terminal 1 for detecting the surface pressure of the liquid to be tested 306 is electrically connected, and the wireless transmitting terminal 1 is arranged above the liquid surface of the liquid to be tested. Specifically, the detection device 3 is provided with a cable 2, and is electrically connected to the wireless transmitting device 1 through the cable 2 to realize communication. In this embodiment, the detection device 3 includes a housing on which two elastic catheters 303 are arranged, and the catheters 303 realize the communication between the housing and the flow chamber through the fluid guide holes 304. In t...

Embodiment 2

[0042] Basically the same as embodiment 1, in this embodiment, in order to take into account the usability of components, the acquisition component that collects the absolute pressure at the bottom of the liquid 306 to be measured is an absolute pressure sensor 310, which has a simple structure and good measurement effect, and has a long service life. long. The absolute pressure sensor 310 is arranged at the bottom of the housing, and the absolute pressure sensor 310 is provided with a pressure guide hole 311, which communicates with the side of the bottom of the housing, and the liquid at the bottom of the liquid to be measured 306 passes through the pressure guide hole 311 to collect the bottom pressure of the liquid , and then obtain the absolute pressure at the bottom of the liquid through the absolute pressure sensor 310, so as to prevent the absolute pressure sensor 310 from being directly placed in the external liquid 306 to be measured and be affected by the outside wor...

Embodiment 3

[0045] A measurement method using the drop-in liquid measurement system described in any one of the above-mentioned embodiments 1-2, comprising the following steps: S1: Put the detection device 3 into the bottom of the liquid to be measured 306, and the wireless transmitting terminal 1 is set on Above the surface of the liquid to be measured 306;

[0046] S2: The liquid to be tested 306 enters the flow chamber through the catheter 303, and then the floater 302 is filled. Because the density of the liquid to be tested 306 is between the two liquids in the liquid chamber, the floater 302 is in the liquid chamber to be tested. 306 moves in the flow chamber under continuous flow, because the initial state of the float 302 is at the top of the flow chamber, so the float 302 will slowly descend until it reaches stability between the two liquids in the liquid chamber, that is, fixed suspension at a certain location in the flow chamber;

[0047] S3: After the float 302 stabilizes, th...

Abstract

The invention discloses a throw-in type liquid measuring system and a measuring method, and belongs to the field of liquid measurement. In order to solve the problems that an existing liquid level measuring device is poor in precision and too large in size, the throw-in type liquid measuring system comprises a detection device, the detection device is electrically connected with a wireless transmitting terminal and comprises a shell, the shell is provided with at least two liquid guide pipes, the liquid guide pipes communicate with a flowing cavity, a floater is arranged in the flowing cavity, and the floater is electrically connected with the wireless transmitting terminal. The outer side of the flowing cavity is sleeved with a liquid cavity, two kinds of liquid which are different in density and incompatible are arranged in the liquid cavity, capacitive sensing pieces are arranged at the upper end and the lower end of the liquid cavity, and the bottom of the shell is provided with collecting components used for collecting the temperature and the absolute pressure of the bottom of the liquid to be measured. Two kinds of liquid serve as comparison liquid, detection is completed after the floater stably suspends, the accurate liquid height is calculated in combination with the wireless transmitting terminal, the comparison liquid is slightly influenced by the environment temperature and the like, the space of parts is reasonably utilized, the size is small, and the measurement precision is high.

Description

technical field [0001] The invention belongs to the technical field of liquid measurement, and more specifically relates to an input liquid measurement system and a measurement method. Background technique [0002] With the rapid development of the Internet of Things, the requirements in the field of measurement are getting higher and higher. Some of the original measurement equipment that is bulky and difficult to install is abandoned by the Internet of Things, but it is difficult to achieve accurate liquid measurement at the expense of volume. position measurement, the present invention aims to reduce the volume as much as possible and reduce the installation cost under the premise of accurate measurement. Most of the existing drop-in liquid level measurement products use a simple piezoelectric pressure sensor measurement solution. Although this solution can measure the liquid level with a known liquid density, it cannot change the liquid composition and cannot sense the t...
