      Ultrasonic water meter is a new type of water meter, which can detect the time difference caused by the change of velocity when the ultrasonic beam propagates along and against the current in the water, analyze the flow rate of the treated water, and further calculate the flow rate of the treated water.
      Because of the lack of mechanical parts in the water meter, it is not afraid of blockage and more accurate measurement. It is widely used in the flow measurement, such as agricultural irrigation, water conservancy monitoring and other major water fields.

      Characteristics of ultrasonic water meter
      Wide range ratio, high measurement accuracy and stable operation
      There are no moving parts inside, no current blocking elements, not affected by impurities in water, long service life
      The output communication function is complete, which meets the requirements of all kinds of communication and wireless networking
      With excellent small flow detection ability, it can solve the problems of many traditional water meters, which is more suitable for gradient water charge, more suitable for the saving and rational use of water resources, and has a broad market and application prospect
      The working principle is that there is discontinuous disturbance in the flow of water, which can be suspended solid particles, bubbles, or small eddy currents. It is these "abnormal points" that become the ultrasonic reflection interface, so that the ultrasonic wave produces a frequency shift △ f (Doppler effect), and the frequency shift △ F is a linear function of the velocity. By measuring the frequency shift △ F, the velocity (or flow) in the pipeline can be measured.
      The prospect of ultrasonic water meter is very broad. Today, the mechanical water meter is gradually eliminated, and the ultrasonic water meter is rapidly seizing the market of large diameter water meter with its unique advantages
