Problems solved by technology

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a new method for measuring the interface of different media in a liquid environment. This method uses a brand-new measurement technology, which overcomes the problems of difficult operation, difficult realization and inaccurate measurement results of previous measurement methods. Various defects, this method can not only measure the interface between two liquids, but also measure the density, liquid level, temperature of the liquid in the storage tank and many parameters of the interface between the two liquids, the method uses advanced instruments, The computer is introduced into the test process of its liquid interface, which is convenient for monitoring, observation and operation. The computer will display or print out the calculation results, which is very intuitive. This method is very easy to implement, and its test results have high precision

Embodiment Construction

[0013] A new method for measuring the interface of different media in a liquid environment. The method for measuring the interface is carried out according to the following steps. Three groups of pressure sensors are fixed on a measuring device with a long fixed rod according to a certain interval in the up and down direction, such as figure 1 , figure 2 As shown, refer to the height of the conventional tank and the height of the interface, such as figure 2 As shown, extend the lower end of the measuring device into the liquid, and put the lower two pressure sensors into the upper and lower range of the liquid interface, such as image 3 , Figure 4 , Figure 5 As shown, the pressure analog signals measured by the three pressure sensors are transmitted to the AD analog-to-digital conversion circuit. The distance is transmitted to the computer, and the computer calculates the result according to a certain calculation method and then displays or prints it out.

Abstract

A method for detecting the interface between different two media in the liquid environment, such as in oil tank, includes fixing 3 pressure sensor sets vertically onto the measuring device with a long rod at intervals, submerging the measuring device in the liquid to make the lower two sensors in interface of difference kinds of liquid, transmitting the measured analog pressure signals to A / D converter and in turn to single-chip computer, processing, and remote transmission for displaying or printing out the result. Its advantages are easy control and high accuracy.

Description

technical field [0001] The invention relates to a new method for measuring the interface of two liquids, which can be used for detecting the interface of two liquids in oil storage tanks in petroleum or petrochemical industries. Background technique [0002] There are many places where it is necessary to measure the interface between two liquid substances, especially in the petroleum or chemical industry. The liquid stored in the storage tank of petroleum products generally contains water. If the interface between the two liquids is not known, it is impossible to calculate each To determine the content of a liquid, sometimes it is often necessary to know other relevant parameters related to the liquid. The methods currently used are too backward and unscientific. The commonly used method is to release water through the valve at the bottom of the tank, close the valve when the oil is discharged, and then measure the depth of the oil to calculate the total weight of the oil. ...
