Which type of displacement meter is used in the receiving line of a Type 3 system?

• A. 600 gallons per minute; positive
• B. 600 gallons per minute; non-positive
• C. 1,200 gallons per minute; positive
• D. 1,200 gallons per minute; non-positive

Answer: (C)

In a Type 3 system, the receiving line typically requires a positive displacement meter rated for higher flow rates, particularly 1,200 gallons per minute. Positive displacement meters are designed to provide accurate measurements of fluid flow by displacing a fixed volume of fluid as it passes through the meter. This makes them particularly suitable for applications where precise measurement is critical, such as in fuel and water systems. Using a positive displacement meter at this flow rate ensures that any variations in fluid characteristics, such as viscosity or density, do not significantly affect the measurement accuracy. Therefore, the choice of a 1,200 gallons per minute positive displacement meter aligns well with the operational needs of a Type 3 system in effectively measuring flow while maintaining reliability and accuracy. Considering the other options, using non-positive displacement meters or meters rated for different flow rates does not meet the specific requirements of a Type 3 system, highlighting the importance of selecting the right type and rating for effective system operation.
