Obstruction Type Flow Measuring Systems
Obstruction type flow measuring systems are used to measure the flow rate of fluids by creating a constriction in the flow path. The differential pressure created due to the constriction is used to determine the flow rate. The following represents obstruction type flow measuring systems:
Flow Nozzle Device
A flow nozzle device is a type of obstruction meter that consists of a converging inlet section, a throat section with a smaller diameter, and a diverging outlet section. The fluid flows through the converging section and reaches the throat section, where the velocity of the fluid increases and the pressure decreases. The pressure difference between the inlet and the throat section is measured to determine the flow rate.
Advantages:
- Low permanent pressure loss
- High accuracy
- Suitable for high flow rates
Disadvantages:
- Sensitive to upstream disturbances
- Requires a long straight pipe upstream
Conclusion
Among the given options, flow nozzle device represents obstruction type flow measuring systems. It is a reliable and accurate method to measure the flow rate of fluids. However, it requires proper installation and maintenance to ensure accurate results.
