Ultrasonic flowmeter

■GENERAL INFORMATION
 CS  series ultrasonic flowmeter and ultrasonic industrial water meter are a kind of  time difference type ultrasonic flowmeter,which is design adopt to advanced  technology,suitable for continuously measuring the most of the clean uniform  liquid flow which do not contain large concentration of suspended particles or  gas under the condition of industrial.Measuring all kinds of liquid online for  long time,can be widely used for the industrial of tap water, heating supply,  water conservancy,metallurgy,chemical,mechanical, energy and so on.Ultrasonic  flowmeter can be used for production monitoring and energy conservation  monitoring,which is the most important instrument for flow measuring.
 ■Measuring Principle

When  ultrasonic beam transmit in liquid,the flow of liquid will have a little change  for the  acoustic transit time,and the  transit time change is proportional to liquid flow speed,the relationship show  as following graph:
 

θ is the angle of sound beam and  liquid flow direct
 M is the line times of sound beam  transit direct in liquid
 D is the tube diameter
 Tup is the transit time of sound beam  in positive direction
 Tdown is the transit time of sound  beam in opposite direction
 △T=Tup Tdown is time difference
 V is flow speed
 So accurately measure the various  parameters in formula,can know the flow in tube.

■Ultrasonic Flowmeter Composition and  Technical Parameters
 Ultrasonic flowmeter is composition of  main flowmeter,sensor and accessories.According to the different condition of  usage,tube and installation,can be divided as following:
 Ultrasonic flowmeter=Main  flowmeter+sensor+accessories
