1. Product introduction
LGBA averaging pitot-tube was called annubar and pipe. It is based on the principle of pitot-tube measured speed. Widely application in the world because of its low pressure loss、low fabricating cost、easy installation and maintenance.
2. Range of application
2.1 nominal diameters：25mm≤DN≤6000mm
2.2 nominal pressures: PN≤25MPa
2.3 medium temperature: t≤650℃
2.4 precision grade: 1, 1.5, 2.5
