Ultrasonic gas velocity meter, model WMPG10 |
Construction and ApplicationsThe WMPG10 Vortex Gas Velocity Meter has been designed for a broad range of (pure and dusted) gas velocity measurements in flow channels, also at low speeds (below 3 m/s), which cannot be measured with impact pressure tubes. The WMPG10 is composed of a measuring probe with compact design, whose longitudinal dimension is 42 mm (passes through a standard M64x4 ferrule) and a meter featuring a graphical display and RAM memory, supplied from an accumulator. The WMPG-10 does not need to know gas density (temperature, pressure and chemical composition) for gas velocity and gas steam volume measurements (after stating a cross-sectional area of the channel). |
