Advantages and disadvantages of ultrasonic flowmeter

Ultrasonic waves are sound waves, but because the frequency is too high for humans to hear them, only machines can be used to detect ultrasonic waves. In the 1970s, scientists used ultrasonic waves in flowmeters to measure the flow of some fluids. Until today, the application of ultrasonic flowmeter has been very extensive. From industry, metallurgy, to aerospace, the application of ultrasonic flowmeters can be seen. So what are the reasons for the widespread use of ultrasonic flowmeters, and what are their advantages? To sum up, ultrasonic flowmeters have the following obvious advantages: 1. Strong anti-interference ability. Since the ultrasonic flowmeter is a flowmeter that does not touch the measured substance, when the measured substance changes, the flowmeter will not be affected, and it still calculates the fluid flow through the flow velocity difference in the pipeline. The size, stability and anti-interference ability are unmatched by other gas flowmeters. 2. The analog signal is good and the interaction is strong. Ultrasonic flowmeters are born with intelligent black technology, and achieve high-precision numerical results through analog signal differences. At the same time, due to the intelligent technology, the human-computer interaction is also very powerful and convenient. 3. It is suitable for the measurement of large-caliber flow fluid. The larger the fluid flow caliber, the more obvious this advantage is. Other flowmeters will change due to the size of the flow caliber, but the ultrasonic flowmeter does not need to be changed, and the size of the caliber will not affect The normal operation of the ultrasonic flowmeter. Although the ultrasonic flowmeter has obvious advantages, it is not a perfect flowmeter, and it also has some unknown shortcomings. 1. Ultrasonic flowmeters cannot work at ultra-high temperatures. Due to the limitation of the temperature resistance of the coupling material in the flowmeter, this kind of flowmeter generally can only work at a temperature of less than 200 degrees Celsius. 2. There must be an accurate measurement path. The general water flow is only a few meters per second, but the speed of sound waves in water is generally 1500m/s. This difference may cause errors in the calculation results. For accurate results, only by selecting a suitable measurement path can the flowmeter work. quality. To understand the ultrasonic flowmeter, you must understand its advantages and disadvantages. The ultrasonic flowmeter of Kaifeng Kaifeng Measurement and Control Technology Co., Ltd. adopts advanced technology at home and abroad, and has provided high-quality and high-guarantee flowmeters for many manufacturers and enterprises.

Nowadays, it is very common for us to utilise in endress hauser ultrasonic flow meter. And the quality of is decisive to production efficiency.

Beijing Sincerity Automatic Equipment Co., Ltd will be familiar with the transformation from a generalist into a manufacturer, and will have the big-picture perspective necessary to stay focused on long-term goals.

Beijing Sincerity Automatic Equipment Co., Ltd’s model also predicts (i) a positive effect of management on firm performance; (ii) a positive relationship between product market competition and average management quality (part of which stems from the larger covariance between management with firm size as competition strengthens); and (iii) a rise (fall) in the level (dispersion) of management with firm age.
