1. What kind of soybean oil flowmeter is generally used, and what kind of flowmeter is used to measure soybean oil? Flow meters are the eyes of industrial production, closely related to the national economy, defense construction, and scientific research. They occupy an important position and role in the national economy and can be used for measuring the flow rate of media such as gases, liquids, and steam. In order to better demonstrate the measurement principle of the flowmeter, the editor uses the wild slag method demonstrated in animation to introduce the working principle of the flowmeter to everyone! 1. Orifice flowmeter working principle: When the fluid fills the pipeline and flows through the throttling device inside the pipeline, the flow beam will experience local contraction, resulting in an increase in flow velocity and low static pressure. Therefore, a pressure drop, or pressure difference, is generated before and after the throttling element. The larger the flow rate of the medium, the greater the pressure difference generated before and after the throttling element. Therefore, the orifice flowmeter can measure the size of the fluid flow by measuring the pressure difference. This measurement method is based on the laws of energy conservation and flow continuity. Job characteristics: ① The throttling device has a simple and sturdy structure, stable and reliable performance, long service life, and low price; ② Widely applicable, all single-phase flows can be measured, and some mixed phase flows can also be applied; ③ The standard throttling device does not require real flow calibration and can be put into use; ④ The installation of an integrated orifice plate is simpler, without the need for a pressure pip_600x400.jpg)
2. Electromagnetic flowmeter The working principle of electromagnetic flowmeter is based on Faradays law of electromagnetic induction. In an electromagnetic flowmeter, the conductive medium inside the measuring tube is equivalent to a conductive metal rod in the Faraday test. The two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows through, an induced voltage is generated. The induced voltage generated by measuring the two electrodes inside the pipeline. The measuring pipeline achieves electromagnetic isolation from the fluid and measuring electrodes through non-conductive lining (rubber, Teflon, etc.). Job characteristics: ① Equipped with a bidirectional measurement system; ② The straight pipe section required for the sensing stove is relatively short, with a length of 5 times the diameter of the pipeline. ③ Small pressure loss ④ measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity ⑤ mainly used in sewage treatment.
