FAQs

The ultrasonic water meter operates on a simple yet ingenious principle: it measures the time difference between the emission and reception of ultrasonic waves. By doing so, it can accurately gauge the speed and volume of water flow without any physical contact with the water itself. This non-intrusive measurement approach enhances the meter's precision and reliability, making it a favored choice in various applications.

Ultrasonic water meters harness ultrasonic technology to measure the velocity of fluid. There are primarily two common types:

  • Transit-style ultrasonic meter: These meters measure the time it takes for ultrasonic waves to travel between two transducers, providing accurate flow data.
  • Doppler-style ultrasonic meter: These meters use the Doppler effect to measure the change in frequency of the ultrasonic wave as it reflects off suspended particles or air bubbles in the water, ideal for water with high particulate content.
