An ultrasonic flow meter is a non-invasive device used to measure the flow rate of liquids or gases within a pipe using ultrasonic sound waves. It operates by transmitting sound waves through the fluid and measuring the time difference or frequency shift between transmitted and received signals. This type of flow meter offers high accuracy, no moving parts, minimal pressure drop, and is ideal for applications where contact with the fluid is undesirable or where installation flexibility is required. Commonly used in water treatment, HVAC systems, oil and gas, chemical processing, and industrial utilities.
