In what units is an electronic motorless mass flow meter system calibrated?

• A. Pounds per hour of fuel flow
• B. Kilograms per second
• C. Gallons per minute
• D. Liters per hour

Answer: (A)

An electronic motorless mass flow meter is calibrated to show the mass flow rate of fuel. In aviation practice, this is expressed as pounds of fuel per hour. Expressing flow as mass per unit time keeps readings consistent despite density changes with temperature or fuel type, and aligns with how engine fuel flow is specified in manuals. Volume-based units would vary with density and aren’t used for this calibration, and while kilograms per second is a valid mass flow unit, pounds per hour is the standard convention in this field.
