Pito modification Promekopribor pressure tubes

Pressure tubes are receivers of total and static pressure. The principle of operation of pressure tubes is based on the measurement of dynamic pressure - the difference between the full and static pressures in the air (gas) flow. Pitot pressure tubes are two tubes of larger and smaller diameter, bent at an angle of 90 degrees and connected in such a way that the tube of smaller diameter is inside the tube of larger diameter. Full pressure is perceived by the hole on the end of the bent inner tube, static pressure - by holes in the wall of the outer tube. Pressure tubes are designed to measure velocity and volume flow rate of air (gas) flow in combination with differential manometers or micromanometers in gas ducts and ventilation systems. They are produced in two versions according to the measuring range of air (gas) flow velocity: version D1 - from 2 to 30 m/s; version D2 - from 2 to 60 m/s
