Annubar flow meter

The Annubar Flow Meter (also known as the Averaging Pitot Tube Flow Meter) is a new type of differential pressure flow detection element developed based on the Pitot tube velocity measurement principle. It outputs a differential pressure signal and, when used with instruments that measure differential pressure, can accurately measure the flow of various liquids, gases, and steam (superheated steam and saturated steam) in circular and rectangular pipelines. With advantages such as high accuracy, low pressure loss, and easy installation, it has gradually replaced orifice plates and other detection elements and is widely used in industries including power (including nuclear), chemical, petroleum, and metal smelting.

Performance Features

High accuracy and stability, with long-term accuracy of ±1% and stability of ±0.1%;

Lightweight, easy to install and remove; models ANB-35 and 45 can be installed and maintained without stopping production;

Beneficial for pipeline layout, requiring only 2 times the straight pipe length before and after installation;

Low pressure loss and minimal energy consumption, with permanent pressure loss of only 2~15% of the differential pressure.
