It’s important to know the discharge depth for many experiments in open channel flow. Using HM 160.53, the discharge depths of ten positions can be measured and displayed simultaneously.
Up to ten measuring points along the experimental section of HM 160 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.
For displaying the curve of the discharge depth along the entire experimental section of 5m, it is possible to use two ten tube manometers at the same time.
