Key Features
• Compliance with International Standards: Manufactured according to the highest standards from USA, UK, Japan, and Switzerland, ensuring precise and reliable results.
• Cylindrical Tank with Adjustable Diffuser: The cylindrical tank is designed with an adjustable diffuser, allowing for accurate flow regulation through different orifices and supporting a range of flow rates.
• Comprehensive Flow Measurement: Provides the ability to measure important flow parameters, such as decrease in flow, contraction of the stream, and energy loss.
• Versatile Orifice Shapes: The apparatus supports various orifice shapes, giving students the opportunity to study the flow characteristics of sharp-edged, circular, triangular, and square orifices.
• Transparent Tank for Visibility: The transparent cylindrical tank allows for clear observation of the water flow and orifice operations.
• Easy to Use: The tank has a mounting system for easy swapping and use of different orifices, allowing for quick adjustments and experiments.
• Sharp-Edged Orifice Included: The apparatus comes with a sharp-edged orifice pre- mounted, allowing students to begin experiments right away.
• Water Overflow Control: An overflow pipe helps maintain the proper water level in the tank, ensuring accurate flow measurements.
