Description

Technical Field

[0001] The invention relates to the technical field of settlement metering equipment, in particular to a strong acid loading trade settlement metering equipment. Background Art

[0002] The volume of a fluid is a function of the temperature and pressure of the fluid and is a dependent variable, while the mass of a fluid is a quantity that does not change with time, space temperature, and pressure. As mentioned above, the flow measurement value of commonly used flow meters, such as orifice flowmeters, laminar mass flowmeters, turbine flowmeters, vortex flowmeters, electromagnetic flowmeters, rotor flowmeters, ultrasonic flowmeters, and elliptical gear flowmeters, is the volume flow rate of the fluid. The amount of fluid involved in scientific research, production process control, quality management, economic accounting, and trade transfer is generally mass. Using the above flowmeter to measure only the volume flow of the fluid often cannot meet people's requirements, and it is usually necessary to try to obtain the mass flow of the fluid. In the past, the mass of the fluid could only be obtained indirectly through correction, conversion, and compensation after measuring parameters such as the temperature, pressure, density, and volume of the fluid. This measurement method has many intermediate links, and the accuracy of mass flow measurement is difficult to guarantee and improve. With the development of modern science and technology, some metering methods and devices for directly measuring mass flow have emerged one after another, thus promoting the progress of flow measurement technology.

[0003] A mass flowmeter is disclosed in the patent document with announcement number CN110044432B, which includes: a protective shell, a accommodating space is provided in the protective shell; a circulation component, embedded in the accommodating space; and a measuring component, including a detection component and a processing component, the detection component is connected to the processing component, wherein the detection component is arranged on the delivery pipe of the circulation component, and the processing component is embedded and installed on the protective shell; wherein the circulation component also includes a liquid inlet end, a liquid outlet end and a connecting part, the liquid inlet end and the liquid outlet end are respectively arranged at the two ends of the delivery pipe, and the connecting part is arranged on the liquid inlet end and the liquid outlet end; the arranged protective shell, circulation component and measuring component are convenient for operators to install, replace and disassemble, and the operation is simple, convenient and fast, saving time and effort, and is convenient for popularization and use.

[0004] However, the above patent document is not convenient for intercepting impurities in the fluid during use, and the corrosion resistance of the inner wall of the pipeline is poor, which affects the measurement accuracy.

When the mass flow meter body 9 flows through a strong acid fluid, the weight of the mass flow meter body 9 increases, and then it moves vertically downward by a certain distance. When the displacement distance of the mass flow meter body 9 monitored by the displacement sensor reaches a preset threshold, the displacement sensor sends an instruction to the controller, and the controller controls the micro motor 4 to automatically open and close, thereby automatically opening and closing the filtering mechanism.
