[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1 As shown, the utility model provides a multifunctional integrated online measuring device based on the float principle, comprising:

[0021] A porous flow-blocking sleeve 1, a plurality of limiters 2, a plurality of floats 3, a conductivity electrode 9, a temperature sensor 4, a sealing flange 5, a buoyancy sensor 6, a pressure sensor 7, and a float guide rail 8;

[0022] The porous flow-blocking sleeve 1 is fixed below the sealing flange 5, the buoyancy sensor 6 and the pressure sensor 7 are both arranged on the sealing flange 5, the float guide 8 is connected to the sealing flange 5, the limiter 2 is symmetrically arranged at the bottom of the float guide 8, the float 3 is symmetrically arranged on the float guide 8, the float 3 is arranged above the limiter 2, and the conductivity electrode 9 and the temperature sensor 4 are both installed on the flange;

[0023] Liquid can pass through the porous flow-blocking sleeve 1, which plays a role in stabilizing the flow to prevent the liquid flow from interfering with the test. The limiter 2 is used to prevent the float 3 from falling off. The float 3 is used to generate buoyancy in the fluid and is connected to the buoyancy sensor 6. The buoyancy sensor 6 is used to convert the buoyancy into an electrical signal. The conductivity electrode 9 is used to measure the conductivity of the fluid. The temperature sensor 4 is used to measure the temperature of the fluid. The pressure sensor 7 is used to measure the pressure of the flow. The sealing flange 5 is used to install the conductivity electrode 9, the temperature sensor 4, the buoyancy sensor 6 and the pressure sensor 7 on the container.

[0024] Specifically, the sealing flange 5 is used to seal and install the measuring device on a reactor, a storage tank or a pipeline.

[0025] Specifically, during measurement, the float 3 is acted upon by the buoyancy given by the fluid, and the float acts on the buoyancy sensor 67 to convert the buoyancy signal into an electrical signal, which is transmitted through the connecting line.

[0026] The measuring device is provided with a pressure sensor 7 for measuring the fluid pressure signal, and is also provided with a conductivity electrode 9 and a temperature sensor 4, and the signal is transmitted through a connecting line. When the float is immersed in the fluid, the float is subjected to a buoyancy F 浮 =ρgV, when the forces are balanced, we have: F 浮 =mg+F 压 , F 压 The supporting force given to the float by the upper buoyancy sensor 6 can be obtained through signal transmission.

[0027] Where m is the mass of the float, which is a constant; V is the volume of the float, which is a constant; g is the gravitational acceleration constant, m / s2; thus, the fluid density can be obtained According to the pressure of a certain liquid level in the container, P 液 =ρgh, and P 液 =P 压 -P0; where P 液 is the pressure generated by the liquid at a certain height, P 压 The value can be obtained from the pressure sensor 78, where P0 is the atmospheric pressure.

[0028] From this, the liquid level can be calculated

[0029] Furthermore, the float, the conductivity electrode 9, the temperature sensor 4, the buoyancy sensor 6 and the pressure sensor 7 are all made of corrosion-resistant materials.

[0030] Furthermore, the float guide rail 8 and the float are both arranged inside the porous blocking sleeve 1 , and the float can slide along the float guide rail 8 .

[0031] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0032] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. At the same time, for those skilled in the art, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
