Cooling water ultrasonic flowmeter

The cooling water ultrasonic flowmeter first needs to give you a popular science about what is the cooling water ultrasonic flowmeter. The cooling water ultrasonic flowmeter is in the production process of the enterprise. In order to test the efficiency of the circulating water cooling system, it is necessary to count the circulating water consumption, that is, to Measure the circulating water flow in the pipeline. Circulating water flow detection methods are mainly ultrasonic method and volume method. Today, I will mainly introduce to you the detection principle, composition, installation and application of the external clamp cooling water ultrasonic flowmeter to the circulating water pipeline. The successful application of the cooling water ultrasonic flowmeter has made up for the inherent shortcomings of the company's process design, improved the level of circulating water flow detection, and is conducive to the optimization of the company's circulating water energy structure.　　The so-called circulating water refers to water that can be recycled as a carrier of heat in the production process of an enterprise. The beginning is a circulating pool with a cooling system, and the end is the heat exchange equipment in the production workshop. There are many types and quantities of heat exchange equipment in biochemical enterprises, so the circulating water pipelines are intricate and complicated. If each circulating water pipeline is installed with a flow rate, it will be a considerable expense. Therefore, in order to reduce the investment cost in the initial stage of design, most manufacturing enterprises did not install ultrasonic flowmeters for cooling water in the circulating water pipelines. However, in order to grasp the operating efficiency of all heat exchange equipment in the production process, it is necessary to detect the flow rate of the circulation in the pipeline.　　 Cooling water ultrasonic flowmeter is a non-contact instrument, suitable for measuring the flow of fluids that are not easy to contact and observe and large pipe diameters. It can measure the flow of open water flow in conjunction with the water level gauge. Using the cooling water ultrasonic flowmeter, there is no need to install the measuring element in the fluid, so it will not change the flow state of the fluid, and no additional resistance will be generated. The installation and maintenance of the instrument will not affect the operation of the production pipeline. Therefore, the application of the cooling water ultrasonic flowmeter can well solve the problems of the above-mentioned enterprises. Compared with the traditional electromagnetic flowmeter, it can be said that the ultrasonic flowmeter is an ideal energy-saving flowmeter.　　 The development of cooling water ultrasonic flowmeter: 　　 Since 1928, the first cooling water ultrasonic flowmeter was successfully developed and patented, and it has a development history of more than 80 years. In the past 20 years, especially in the past 10 years, due to the rapid development of high-speed digital signal processing technology and micro-processing technology, the development of new probe materials and process technology, and the research progress in channel configuration and flow dynamics, ultrasonic flow measurement technology has been achieved. The working principle of ultrasonic flowmeter for cooling water is based on the fact that the ultrasonic flowmeter for cooling water is based on the information of the fluid velocity when the ultrasonic wave propagates in the flowing fluid, such as downstream and The propagation velocity of the countercurrent is different due to the superimposed fluid velocity. Therefore, the flow rate of the fluid can be detected by the received ultrasonic wave and converted into a flow rate. Ultrasonic flowmeter is composed of three parts: ultrasonic transducer, electronic circuit and flow display and accumulation system. The ultrasonic transmitting transducer converts electrical energy into ultrasonic energy and transmits it to the fluid to be measured. The ultrasonic signal received by the receiver is amplified by the electronic circuit and converted into an electrical signal representing the flow rate for display and totalizer for display And accumulate. In this way, the flow detection and display cooling water ultrasonic flowmeter selection: 　　 common cooling water ultrasonic flowmeter mainly includes portable cooling water ultrasonic flowmeter, handheld cooling water ultrasonic flowmeter and fixed cooling water ultrasonic flowmeter, portable The characteristics of cooling water flow meters are compared as follows: Portable ultrasonic flow meters for cooling water are non-contact measurement methods, small in size and easy to carry. It is suitable for on-site measurement of sound conducting media of various sizes of pipes. However, the cooling water ultrasonic flowmeter has certain requirements for the material of the pipe section, and it must be a uniform medium. The measuring medium includes water, industrial sewage, acid and alkali liquid, various oils and other liquids that can conduct sound waves. The measurement flow velocity range is (0～±30) m/s, and the measurement accuracy level is better than 1%.　　 This time I mainly introduce the cooling water ultrasonic flowmeter to everyone. The main production area of u200bu200bthis flowmeter is concentrated in Hangzhou, and it is also a relatively well-known manufacturer in China.
