The HM 225.01 Tube Manometer is used in combination with the HM 225 Aerodynamics Trainer for measuring air pressures and flow velocities. The unit comprises 16 manometers with a mm-scale on a swivelling panel. The panel can be fixed at three tilt positions. This permits the usage of slanted tube manometers for measuring very small pressure differences. The supply of water to the manometer is performed centrally using a tank, measuring glands are provided at the top of each manometer. The manometer is mounted using locking bolts and can be adjusted in height.
