1. What is Fill-Rite Meter Calibration?

Definition: This calculator determines the calibration ratio (R) for Fill-Rite meters by comparing actual flow rate to target flow rate.

Purpose: It helps ensure accurate fuel dispensing by identifying needed adjustments to the meter's calibration.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Calibration ratio (dimensionless)
• \( Q_{actual} \) — Actual measured flow rate (GPM)
• \( Q_{target} \) — Desired target flow rate (GPM)

Explanation: The ratio compares what the meter is actually dispensing versus what it should be dispensing.

3. Importance of Meter Calibration

Details: Proper calibration ensures accurate fuel measurement, prevents financial losses from under/over dispensing, and maintains compliance with measurement standards.

4. Using the Calculator

Tips: Measure actual flow rate using a calibrated container and stopwatch. Enter both actual and target flow rates in GPM. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What does the calibration ratio tell me?
A: A ratio of 1 means perfect calibration. Values > 1 indicate the meter is over-dispensing, while values < 1 indicate under-dispensing.

Q2: How often should I calibrate my meter?
A: Recommended annually or after any significant maintenance. More frequently for high-volume operations.

Q3: What if my ratio is outside acceptable range?
A: Consult the meter manual for adjustment procedures or contact Fill-Rite technical support.

Q4: What's a typical acceptable calibration range?
A: Most standards require ±0.5% accuracy (ratio between 0.995 and 1.005).

Q5: Can I use this for other flow meters?
A: The principle applies to any positive displacement meter, but consult manufacturer specs for specific requirements.
