The pitotstatic tube HM 163.50 is used to measure the flow velocity in the experimental flume HM 163. It measures the static pressure and the total pressure at any point of the flow. The pressure difference corresponds to the dynamic pressure, from which the flow velocity can be calculated. The differential pressure display indicates the dynamic pressure.
The pitotstatic tube can be moved vertically. A scale indicates the corresponding vertical position of the measurement.
HM 163.50 is mounted on the moveable instrument carrier HM 163.59 so it can be used along the length and width of the experimental section.
