In the long-term development, ultrasonic flowmeters have gradually replaced traditional measurement methods such as turbine flowmeters, differential pressure flowmeters and electromagnetic flowmeters. Through multi-angle analysis, it can be seen that the ultrasonic flowmeter has the following advantages in practical applications.
First of all, ultrasonic flowmeters are more convenient and fast to install and maintain in practice, and compared with other flowmeter methods, ultrasonic flowmeters are more convenient and fast to install and maintain. For large-diameter flow metering systems, the advantages of ultrasonic flowmeters in this regard are very obvious and can be saved. In recent years, with the practical application of ultrasonic flowmeters in various research fields, when installing and maintaining ultrasonic flowmeters, there is no need to consider whether to cut off the flow or punch holes in official roads.
Secondly, the measurement diameter of the ultrasonic flowmeter is relatively large, which can be measured to the greatest extent during measurement, which is also the outstanding advantage of the ultrasonic flowmeter. The applicable diameter range of the ultrasonic flowmeter is relatively large, and the flow rate can be freely measured within a certain range. When the measured diameter exceeds a certain range, the flowmeter may be restricted by various external factors, making it difficult to meet specific measurement requirements. At this time, it is possible to consider the use of ultrasonic flowmeters to solve these problems in a targeted manner, and to measure any diameter at the same time. Also, the diameter range does not affect the price of an ultrasonic flowmeter, while the price of other flowmeters tends to vary with the diameter range.
Thirdly, the measurement reliability of the ultrasonic flowmeter is high, whether it is wet installation or external clamp installation, it will not affect the fluency of the measured flow, and there is no pressure loss. At the same time, the sensor with the microcomputer as the core can solve the problem of power failure and weak signal by using timing methods such as phase-locked loop, so that the measurement reliability of the ultrasonic flowmeter is higher.
Fourth, the measurement of the ultrasonic flowmeter will not be affected by fluid-related parameters, such as the physical properties of the fluid, conductivity, roughness and other related parameters will not affect the measurement of the ultrasonic flowmeter. In addition, the measurement results of the ultrasonic flowmeter can be automatically displayed and printed by the computer automatic control system, and network operation can be realized.
