I. Product Overview
The KBF200 Annubar flowmeter (also known as a averaging pitot tube flowmeter) is a type of differential pressure (DP) flowmeter based on the pitot tube velocity measurement principle. It is primarily used for measuring the flow of various liquids, gases, and steam (including saturated and superheated steam) in industrial processes. It offers significant advantages, particularly in large-diameter pipeline applications (DN20 to DN12000). Its design theory complies with the Bernoulli equation and can be verified according to relevant national standard procedures.
2.Technical data
