It is important to know the discharge depth for many experiments in open channel flow. Using HM 161.53, the discharge depths of 20 positions can be measured and displayed simultaneously.
Up to 20 measuring points along the experimental section of HM 161 are connected to the tube manometers using hoses. The manometers are fitted with scales directly indicating the discharge depth of the corresponding measuring point. The holding device of the tube manometers can mounted directly at the experimental section. The holding device is fitted with a spirit level and screws to compensate for the inclination of the experimental section.
To display the curve of the discharge depth along the entire experimental section, it is possible to use several 20 tube manometers at the same time.
