Determine Meter K-Factor
A meter K-factor is determined by dividing the total pulses generated by a flow meter by the known unit volume (e.g., gallons or liters) that passed through it during calibration, typically expressed as pulses/gallon or pulses/liter. This value is required to convert the pulses measured by the Eyedro Flow Meter into volumetric and flow rate units for presentation in the MyEyedro Cloud service.
Methods to Determine K-Factor
- Calibration Certificate (Recommended): The most accurate K-factor is provided by the manufacturer on the flow meter tag or calibration certificate, determined through factory testing. Occasionally these are marked on the meter register.
- On-Site Calibration (Volumetric/Gravimetric):
- Run a known volume of gas or fluid (V
) through the meter.
- Count the total pulses (
P) generated.
- Calculate
K = Total Pulses (P) / Total Volume (V).
- Run a known volume of gas or fluid (V
Key Considerations
- System Factors: Fluid viscosity, temperature, pressure, and pipe installation specifics can impact the K-factor.
