ZM7105 Over Weirs Flow Measuring Fluids Engineering Training Equipment Educational Equipment Vocational Training EquipmentI. Product Overview
1.1Overview
The hydraulic calculation formulas for weir flow are all semi-empirical formulas, and parameters such as the flow factor in the formula need to be obtained through experiments. Issues such as the flow capacity of weirs in important projects so far still need to be determined through model tests. Weir flow experiments are important for training engineering test capabilities.
The purpose of the weir flow measurement experiment is mainly to understand and master the measurement method of weir flow, explore the changing rules of weir flow, and provide theoretical support and experimental basis for practical engineering applications. At the same time, students' practical operation ability and data analysis ability can be improved through experiments.
The measurement of weir flow is based on the basic principles of hydraulics, and the flow is determined by measuring the relationship between the weir water level and flow. Depending on the shape and size of the weir, the weir flow formula can vary.
1.2 Features
1. The equipment is compact, flexible, light-weight and easy to move, and can be used for experiments in a variety of scenarios.
2. The whole body of the equipment is made of waterproof materials, which not only makes it waterproof but also extends the life of the equipment.
3. The equipment scale mark adopts integrated laser silk screen printing, which is not easy to fall off, and is anti-aging and water-erosion resistant.
4. The equipment has high hardness and is stable when placed on the device platform or in other experimental scenes. The transparent visualization of experimental phenomena during the experiment is very obvious.
