What is K factor in fuel flow?

Table of Contents

The K-factor is a constant, referring to the number of measurable pulses required for a given volume of fuel to pass through the point where flow is being measured. Sensors measuring these pulses send the signal to an onboard chip that converts the pulses into volume, using the K-factor.

What is K value in flow meter?

For aircraft fuel flow meters, K-factor refers to the number of pulses expected for every one volumetric unit of fluid passing through a given flow meter, and is usually encountered when dealing with pulse signals.

How do you calculate K factor calibration?

Dividing the total number of pulses generated by the specific amount of liquid product that passed through the PTF determines the K-Factor.

How do you adjust K factor for flow?

If the flow rate was given in units per minute the totalizer K-factor (for whole units) is obtained by multiplying the rate K-factor by 60. If the flow rate was given in units per hour the totalizer K-factor (for whole units) is obtained by multiplying the rate K-factor by 3600.

What is the difference between meter factor and K-factor?

The meter base K-factor is used in the flow computer’s calculation of the quantity of liquid delivered, so it must be considered during the testing of a meter. The proving K-factor (PKF) is used to calculate the correct meter factor based on the pulses it receives while a known amount of liquid passes through the SVP.

How do you calculate K-factor from flow meter?

The K-factor is the frequency divided by the flow rate => [1/s] / [g/s] = 1/g. Knowing the K-factor for each calibration point, the factory determines the best fitting K-factor for that particular flowmeter. Calibration points are determined by averaging all K-factors.

What is K-factor calibration?

Calibration (K) factors are the numbers that must be programmed into the instruments. They convert the pulse output from the sensor (pulses per litre) to instrument readings and depend on the inside diameter of the pipe and specific fitting.

What is K-factor in vortex flow meter?

K-Factor. The vortex K-Factor is the proportionality constant that is used to relate the measured frequency to a volumetric flow rate. The K-Factor is determined using a flow lab calibration.

What is a K-factor?

K Factor is a metric for app developers that reveals your app’s virality, by measuring how many additional users each of your existing users brings along to the app. The term K Factor actually comes from the world of medicine, where it’s used as a metric to measure how quickly a virus spreads.
