Ultrasonic flowmeter and principle
2011-12-1 9:33:04

What is an ultrasonic flow meter:

就是通过检测流体流动对超声束(或超声脉冲)的作用以测量流量的仪表。 Ultrasonic flowmeter is an instrument that measures the flow by detecting the effect of fluid flow on the ultrasonic beam (or ultrasonic pulse).

Principle of ultrasonic flowmeter

可分为传播速度差法(直接时差法、时差法、相位差法和频差法)、波束偏移法、多普勒法、互相关法、空间滤法及 According to the principle of signal detection, ultrasonic flowmeters can be divided into propagation velocity difference methods (direct time difference method, time difference method, phase difference method, and frequency difference method), beam shift method, Doppler method, cross correlation method, and spatial filtering method. and

Noise method


    和电磁流量计一样,因仪表流通通道未设置任何阻碍件,均属无阻碍流量计,是适于解决流量测量困难问题的一类流量计,特别在大口径流量测量方 Ultrasonic flowmeters are the same as electromagnetic flowmeters.Because there are no obstructions in the flow channel of the instrument, they are all unobstructed flowmeters.They are a type of flowmeter that is suitable for solving the difficult problem of flow measurement.

It has outstanding advantages. In recent years, it is one of the fastest-growing types of flowmeters.
