Embodiment Construction
[0008] As shown in Figure 1, the present invention is a kind of storage tank volume automatic measuring system, has a water tank 1, connects with measuring water tank 8 through a pipeline, is equipped with a filter 2, a centrifugal pump 3, a The standard flow meter 4 and the centrifugal pump 3 adjust their rotating speed through the frequency converter 11. The frequency converter 11 inputs the flow rate signal of the test liquid flowing through the centrifugal pump 3 into the operational amplifier 12. A pressure sensor 5 and a temperature sensor 5 are respectively installed on the above-mentioned pipelines. The sensor 6, the pressure sensor 5 and the temperature sensor 6 respectively input the pressure and temperature information of the test liquid into the operational amplifier 12, and an electromagnetic reversing valve 7 is connected in parallel with the measuring water tank 8, and the measuring water tank 8 and the measured storage tank 9 are connected by A pipeline connecti...

The invention provides a storage tank volume automatic measure system, the transducer 11 inputs the flow speed signal of the tested liquid which flows through the centrifugal pump 3 into the operational amplifier 12, a pressure sensor 5 and a temperature sensor 6 are separately installed on the pipeline, the pressure and the temperature information of the test liquid are separately inputted into the operational amplifier 12, a solenoid directional valve 7 and a water tank for measurement 8 are connected with the pipeline in parallel connection, the water tank for measurement 8 and the tested storage tank 9 are connected by a pipeline, a magnetostrictive liquid level sensor 10 is fixed on the tested storage tank 9, the operational amplifier 12 is connected with the computer 15 through the A / D converter 13, and the input and output interface 14, the standard flow gauge 4 gives the volume of the tested liquid which goes into the measurement system, the magnetostrictive liquid level sensor10 collects the liquid height signal in the tested storage tank 9, the signal is transferred through the operational amplifier 12 and A / D converter 13 and the input and output interface 14, the liquid height reading in the tank is automatically displayed on the computer.
Description
technical field [0001] The invention relates to a measuring device for the volume of a container. Background technique [0002] In the production and operation of petroleum processing, manufacturing and transportation, product storage and transportation is an important link, especially the storage and transportation of liquid media such as crude oil, refined oil, and light hydrocarbons. In the process of storage and transportation, the measurement of liquid is often an indispensable link, so in practice, it is often encountered how to calculate the volume of storage tanks for other purposes such as refueling equipment, automobile tank trucks, and self-made vehicle volumes. Accurate and rapid detection, and give questions related to the detection results. [0003] The current detection method is the volumetric method. According to the volume of the tank to be tested, standard tanks of different sizes are selected, and water is used as the detection liquid, and the measuremen...
