Description
Technical field
The utility model relates to a kind of electronic liquid level gauge, belongs to electronic circuit technology field.
Background technology
Now electronic liquid level gauge is commercially little, and seldom has the function of display liquid level in real time, and need for some the container measuring liquid level, the height of liquid level temperature can only be estimated by range estimation, and neither one is mode easily.
Utility model content
The utility model provides a kind of electronic liquid level gauge.The function of density measurement uniform liquid liquid level can be realized.
The technical solution of the utility model is as follows:
A kind of electronic liquid level gauge, comprises support, and rack-mount keyboard and display, and described display is for showing testing container liquid level, and described keyboard is for inputting numerical value; In described support, AD conversion module is installed, control module, described AD conversion module is connected with detection module, described detection module comprises a flexible pipe, be arranged on weight and the pressure transducer at flexible pipe two ends, described weight is positioned at the bottom of liquid container to be detected, described pressure sensor is positioned at outside container, same plane is in container bottom, described AD conversion module is converted to digital signal the simulating signal on pressure transducer, and described control module is connected with display with AD conversion module, keyboard respectively; Described control module is carried out process the data that detection module collects and is drawn testing container liquid level, and the data of process are shown by display.
Above-mentioned support can oscilaltion.
The beneficial effect that the utility model reaches:
The utility model can show in real time to the page height of liquid in container, and measuring equipment outside, adds service life of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model local module schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, a kind of electronic liquid level gauge, comprises support 4, and the keyboard 7 be arranged on support 4 and display 8, and described display 7 is for showing testing container 1 liquid level, and described keyboard 7 is for inputting numerical value; Described support 4 is provided with AD conversion module 9, control module 5, described AD conversion module 9 is connected with detection module, described detection module comprises a flexible pipe 2, be arranged on weight 3 and the pressure transducer 6 at flexible pipe 2 two ends, described weight 3 is positioned at the bottom of the container 1 of liquid to be detected, described pressure sensor 6 is positioned at outside container 1, same plane is in bottom container 1, described AD conversion module 9 is converted to digital signal the simulating signal on pressure transducer 6, and described control module 5 is connected with display 8 with AD conversion module 9, keyboard 7 respectively; Described control module 5 is carried out process the data that detection module collects and is drawn testing container liquid level, and the data of process are shown by display 8.
Preferably, above-mentioned support 4 can oscilaltion.
The utility model is worked by following principle:
First flexible pipe is filled liquid, one termination pressure transducer, another termination weight is placed on liquid bottom, pressure transducer and liquid bottom are positioned at sustained height, just ensure that liquid bottom pressure and equal with the pressure of pressure sensor contacts partially liq, by measuring the pressure of liquid at pressure transducer place, obtaining the pressure of liquid bottom, fluid density, the pressure transducer lifting surface area of testing liquid entered from the keyboard carry out, and calculate liquid level.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
