Internet of Things pressure liquid level gauge and liquid level measuring method

Abstract

The invention discloses an Internet of Things pressure liquid level gauge and a liquid level measuring method. The Internet of Things pressure liquid level gauge comprises a first calculating module,a second calculating module, a third calculating module, a first uploading module and a second uploading module, the first calculating module is used for obtaining a first voltage value output by a sensor at a first time and obtaining a first pressure value calculated according to the first voltage value, the second calculating module is used for obtaining a second voltage value output by the sensor at a second time and obtaining a second pressure value calculated according to the second voltage value, the third calculating module is used for calculating a time difference between the second time and the first time and a pressure difference between the first pressure value and the second pressure value, the first uploading module is used for uploading the first pressure value, and the second uploading module is used for uploading the second pressure value to replace the first pressure value when the time difference is greater than a set interval value or the pressure difference is greater than a preset pressure threshold. The remaining capacity of materials can be effectively monitored.

Description

technical field [0001] The invention relates to the technical field of pressure liquid level testing, in particular to an Internet of Things pressure liquid level gauge and a liquid level measurement method. Background technique [0002] The Internet of Things organically connects everything in life through the network. Intelligent management and remote monitoring are important components of the Internet of Things. Applying the Internet of Things to the distribution of liquids can not only improve the efficiency of liquid distribution, but also Timely supply out of stock. In the liquid distribution link, the pressure state of the liquid in the distribution is mainly checked in real time through the pressure level gauge. The pressure level gauge is mainly used to measure the volume flow rate of the conductive liquid and the slurry in the closed pipeline. Including acid, alkali, salt and other highly corrosive liquids. The product is widely used in petroleum, chemical indust...

Problems solved by technology

[0003] At present, in the liquid distribution process, the traditional flowmeter cannot effectively monitor the remaining amount of the material, resulting in the inability to replenish the insufficient material in time, causing certain losses to the user
