Flow meter for flow measurement of corrosive media

Abstract: The flow measurement information of the corrosive medium of the flow meter is provided by the excellent manufacturers of flow meters and flow meters. There are many types of media measured by the flowmeter, including ordinary types and corrosive media. For corrosive media, anti-corrosion and corrosion-resistant treatment must be done in the selection of flowmeters. Below and the technology of Shunda flowmeter manufacturers, let's explain about flowmeters. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the flow measurement article of flowmeters for corrosive media. There are many types of media measured by the flowmeter, including ordinary types and corrosive media. For corrosive media, anti-corrosion and corrosion-resistant treatment must be done in the selection of flowmeters. The following flowmeter manufacturers' techniques are used to explain the flow measurement of corrosive media in flowmeters, as follows: 1. Corrosion phenomenon Corrosion is a phenomenon in which metals are damaged due to chemical action in their environment. All metals and alloys can be resistant to corrosion in certain environments, but are susceptible to corrosion in others. Generally speaking, industrial metal materials that are resistant to corrosion in all environments do not exist. 2. Damage of corrosive medium to flow measuring instrument Corrosivity of medium is a serious threat to flow measuring instrument: a. Corrosive medium corrodes the key parts of flow measuring instrument in direct contact with the medium, causing damage and loss of function. For example, corrosion causes the diaphragm of the differential pressure transmitter to be damaged, and the silicone oil leaks out and completely fails. Electromagnetic flowmeter electrodes due to corrosion caused medium leakage, resulting in the burning of the excitation coil, etc. b. The key components of the flow measuring instrument are corroded by the corrosive medium for a long time and change the geometric size, resulting in the decrease of the accuracy of the instrument. For example, after the rotor in the rotameter is corroded by the fluid, the external size is reduced, resulting in a low flow indication value. Another example is that the vortex generator in the vortex flowmeter is corroded by the fluid and the width dimension is reduced, and the surface of the upstream surface becomes rough, thereby causing the flow coefficient to change. c. Shortened instrument life. For example, the conical tube in the metal tube rotameter and other parts, after a few years of use, the welding part is rotted through. d. If the leakage of corrosive medium is not detected and dealt with in time, it will easily lead to safety and personal accidents. 3. Measures for fluid corrosion in flow measurement a. Regular replacement of instruments Corrosion of metals by corrosive media is varied. Some corrosion is very fast, that is, general corrosion, and some corrosion is slight, and the speed is very slow, that is, local corrosion. When making instrument selection, you should analyze the specific situation and then make a decision. b, avoid heavy and light. Avoiding the heavy and the light is to choose the measurement plan reasonably based on the in-depth understanding of the technological process and the characteristics of the relevant medium, which can also achieve the purpose of measuring or controlling the production process, avoiding the highly corrosive parts, and choosing the less corrosive parts. position, and even change the type of parameter being tuned. Above are“”I hope everyone has to help. After more than ten years of development, the flowmeter manufacturer has always been based on honest operation, customer demand first, and quality assurance as the priority. Continuous efforts are made to develop new technologies, improve product performance, use high-quality materials, and be meticulous about product quality, which is why it has been well received by customers. All my colleagues look forward to flying with you. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
