The technical scheme of the utility model is as follows:

An electronic liquid level gauge, including a bracket, and a keyboard and a display installed on the bracket, the display is used to display the liquid level of the container to be measured, and the keyboard is used to input values; an AD conversion module is installed in the bracket , a control module, the AD conversion module is connected with a detection module, the detection module includes a hose, weights and pressure sensors arranged at both ends of the hose, the weight is located at the bottom of the liquid container to be detected, the pressure sensor The sensor is located outside the container and is on the same plane as the bottom of the container. The AD conversion module converts the analog signal on the pressure sensor into a digital signal, and the control module is connected with the AD conversion module, keyboard and display respectively; the control module detects The data collected by the module is processed to obtain the liquid level of the container to be measured, and the processed data is displayed on the display.

Above-mentioned support can lift up and down.

The beneficial effects achieved by the utility model:

The utility model can display the page height of the liquid in the container in real time, and the measuring equipment is outside, thereby increasing the service life of the equipment.

Description of drawings

Fig. 1 is a structural representation of the utility model;

Fig. 2 is a schematic diagram of a partial module of the utility model.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Figures 1 and 2, an electronic liquid level gauge includes a bracket 4, a keyboard 7 and a display 8 installed on the bracket 4, and the display 7 is used to display the liquid level of the container 1 to be measured, and the The keyboard 7 is used to input values; the AD conversion module 9 and the control module 5 are installed on the support 4, and the AD conversion module 9 is connected with a detection module, and the detection module includes a flexible pipe 2, which is arranged on two sides of the flexible pipe 2. The weight 3 at the end and the pressure sensor 6, the weight 3 is located at the bottom of the container 1 of the liquid to be detected, the pressure sensor 6 is located outside the container 1, and is on the same plane as the bottom of the container 1, and the AD conversion module 9 converts the pressure The analog signal on the sensor 6 is converted into a digital signal, and the control module 5 is connected with the AD conversion module 9, the keyboard 7 and the display 8 respectively; Surface height, processed data are displayed by display 8.

As a preferred solution, the above-mentioned support 4 can be lifted up and down.

The utility model works through the following principles:

Fill the hose with liquid first, connect one end to the pressure sensor, and connect the other end to a heavy object on the bottom of the liquid. The pressure sensor and the bottom of the liquid are at the same height, which ensures that the pressure at the bottom of the liquid is equal to the pressure of the liquid in contact with the pressure sensor. Measure the pressure of the liquid at the pressure sensor to obtain the pressure at the bottom of the liquid, and calculate the height of the liquid level by inputting the liquid density of the liquid to be tested and the force area of the pressure sensor from the keyboard.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and deformations can also be made. And deformation should also be regarded as the protection scope of the present utility model.
