Overview
Ultrasonic flow meters are cutting-edge devices that measure the flow rate of liquids using sound waves. They operate based on the principle of measuring the time difference or frequency shift of ultrasonic signals transmitted and received through the fluid. These meters are non-invasive, highly accurate, and versatile, making them ideal for applications in water treatment, oil and gas, and HVAC systems.
