Introduction to Roots Flowmeter
Roots flowmeters, also known as positive - displacement flowmeters, are widely used in the measurement of gas and liquid flow. They operate based on the principle of trapping a fixed volume of fluid in a measuring chamber and then counting the number of times this volume is filled and emptied. This type of flowmeter offers high accuracy, good repeatability, and is suitable for a wide range of applications, including natural gas measurement in industrial and commercial settings, as well as in the chemical and petroleum industries.
