Overview
Product Overview
Annubar flow meter (also known as averaging pitot tube flow meter) is a differential pressure detection element developed based on the pitot tube velocity measurement principle. It outputs differential pressure signal and is used with differential pressure measurement instruments to accurately measure the flow of various liquids, gases, and steam (superheated and saturated steam) in circular and rectangular pipes. With advantages such as high accuracy, low pressure loss, and easy installation, it gradually replaces orifice plates and is widely used in power (including nuclear), chemical, petroleum, metallurgy and other industries.
Measurement Principle
The high-low differential pressure measurement principle is adopted to measure the pressure difference between the upstream dynamic pressure and downstream static pressure to obtain flow. The unique internal secondary averaging structure provides high accuracy and high repeatability.
