Ultrasonic flow meters application:
Ultrasonic flow meters have many applications, from process flow to custody flow. It is also a common practice to use a clamp-on ultrasonic flow meter to verify other flow meters or for temporary measurement. The article explains what you need to know about the basics of ultrasonic flow measurement and its applications.There are two types of ultrasonic flow meters: Doppler and transit time ultrasonic flow meters. But first, let’s find out more about the working principle. Then we can go through in-depth variations and typical uses. Later, we will highlight the pros and cons and give examples of brands on the market.
