In this application, an input frequency of 80.00 Hz represents a flow
rate of 1,686.8 lpm.
Given:
•Q = flow rate
• F = frequency: 80.00 Hz
• K = K-factor (compensated): 10.772 (via fieldbus configuration
tool)
•C

Other Conditions:
• Fluid = water
• Line size = 80 mm
• Line pressure = 700 kPag
• URV= 2,000 lpm
• LRV= 0 lpm
• Operating temperature = 60 °C
