ANS:C - rotameter

It is possible to integrate an automatic flow controller to a rotameter. Here’s why:

• Rotameter: A rotameter is a device used to measure the flow rate of a fluid in a closed tube. It typically consists of a tapered tube and a float that moves up and down inside the tube based on the flow rate of the fluid. The position of the float indicates the flow rate, with higher flow rates causing the float to rise higher in the tube.
• Automatic Flow Controller: This device is used to automatically adjust the flow rate of a fluid based on preset conditions or signals from sensors. It can regulate the flow by adjusting valves, pumps, or other mechanisms to maintain a desired flow rate.
• Integration: In industrial and laboratory settings, rotameters are often used to measure flow rates manually. However, for automated systems or processes where precise control of flow rate is required, automatic flow controllers can be integrated with rotameters. The controller uses feedback from the rotameter (typically via sensors or electronic readings) to adjust valves or other components to maintain a constant flow rate or vary it as needed.

Therefore, while flow nozzles and venturimeters are primarily used for flow measurement and do not typically integrate automatic flow controllers directly, a rotameter can be integrated with an automatic flow controller to provide automated flow regulation based on real-time flow rate measurements.
