What are the performance characteristics of ultrasonic flowmeter

Currently, two types of ultrasonic flowmeters are commonly used, one is Doppler ultrasonic flowmeter and the other is transit time ultrasonic flowmeter. The Doppler type measures flow using the phase difference method, in which sound waves of a certain frequency move through the fluid. Since the liquid itself has a moving velocity, the frequency or phase of the ultrasonic waves occurs between the two receivers. The relative change by which the velocity of the liquid can be obtained. The time difference type is to measure the flow velocity by the time difference method, that is, the propagation time between two receivers caused by the sound wave of a certain speed due to the fluid flow. By measuring this relative change, the fluid flow rate can be obtained. Introduction to installation methods At present, three installation methods are generally used: W type, V type, and Z type. Choose the installation method according to different pipe diameters and fluid characteristics. Generally, W type is suitable for small diameters (25 to 75 mm), V type is suitable for medium diameters (25 to 250 mm), and Z type is suitable for large diameters (250 mm or more). Accuracy and sensitivity, choose an appropriate installation method so that the measurement signal matches the auxiliary instrument. In order to ensure the measurement accuracy of the instrument, a location that meets certain conditions should be selected: generally, upstream 10D and downstream 5D straight pipe sections are selected; upstream 30D cannot be equipped with pumping, valves and other interference devices. Installation, talk about the installation method of the ultrasonic flowmeter probe. Specifically, the 'coordinate method installation' is used, that is, the outer surface of the pipe is cleaned first, and then the special coupling agent is applied. First, one of the positions of the probe is fixed, and the pipe is wrapped with tape for a week. , measure the perimeter to form the fold trace, and determine the position of another probe track at 1/perimeter.
