Note:

Turndown Ratio Formula: The turndown ratio represents the range of flow rates a flowmeter can accurately measure. A higher turndown ratio indicates better flexibility and precision in measuring varying steam flow rates.

Parameters Explained:

• Maximum Flow: The highest measurable steam flow rate (m³/hr).
• Minimum Flow: The lowest measurable steam flow rate (m³/hr).
• Turndown Ratio: Indicates the accuracy and flexibility of the flowmeter.

Real-Life Applications:

• Power Plants: Used to measure steam flow in boilers.
• Food Industry: Monitors steam usage in sterilization and cooking processes.
• Petrochemical Plants: Ensures accurate steam flow control in refining operations.
• HVAC Systems: Helps in steam-based heating system efficiency.

Conclusion:

A high turndown ratio means the flowmeter can measure a wide range of flows effectively. If the ratio is too low, the system may lack flexibility and accuracy. Selecting the right flowmeter ensures efficiency and cost savings.
