Velocity of a fluid flowing through the pipe is measured by
- Current and turbine meter
- Wire anemometer
- Pitot tube
Piezometer:
- A device that is used to measure liquid pressure in a system by measuring the height to which a column of the liquid rises against gravity or a device that measures the pressure (more precisely, the piezometric head) of groundwater at a specific point is called piezometer.
- One end of the piezometer is connected to the point where the pressure is to be measured and the other end is open to the atmosphere.

Understanding Flow Rate Measurement Devices
In the context of fluid dynamics, various devices are employed to measure the flow rate or velocity of fluids. Each device serves a specific purpose based on the characteristics of the fluid being measured. Among the options provided, option 'B', the Piezometer, is not used to measure flow rate or velocity directly.
Devices that Measure Flow Rate or Velocity
- Current and Turbine Meter:
These devices measure the flow rate by using a rotating turbine. The speed of the turbine is proportional to the fluid velocity, allowing for accurate flow measurement.
- Wire Anemometer:
This device measures the velocity of air or other gases. It uses a thin wire that gets heated, and the cooling effect due to the airflow is used to determine the velocity.
- Pitot Tube:
A Pitot tube measures fluid flow velocity by converting the kinetic energy of the flow into potential energy. It is widely used in aerodynamics and fluid mechanics.
Piezometer Explanation
- Piezometer:
A piezometer is primarily used to measure the static pressure in a fluid. It provides information on fluid height or pressure but does not directly measure flow rate or velocity. Instead, it is used to determine the pressure head in a system.
Conclusion
In summary, while devices like turbine meters, wire anemometers, and Pitot tubes are specifically designed to measure flow rate or velocity, a piezometer is not suitable for this purpose. It focuses on pressure measurement, making option 'B' the correct answer.
