How do you calculate K-factor for a turbine flow meter?

How do you calculate K-factor for a turbine 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.

What is meter K-factor?

The “K-Factor” of a water meter is the manufacturers way of describing liquid flow through their meter. A K-factor of “100” means that there are 100 “pulses” produced for each gallon of water.

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 K-factor in vortex flow meter?

The vortex K-Factor is the proportionality constant that is used to relate the measured frequency to a volumetric flow rate. In the flow lab, the number of pulses from the vortex meter are counted and compared to the volume of fluid that has passed through the meter to give the K-Factor units of pulses per volume.

What is K factor in air flow?

The K factor is the point at which the size of the box, shown in inches, converges with the maximum airflow at 1″w.g. velocity pressure (on the far right).

What is K factor calibration?

The K factor relates the metabolite signal to that obtained from tissue water, i.e., the procedure uses tissue water as an internal calibration standard. The K value is obtained from an experimental calibration measurement in a phantom using a metabolite of known concentration.

How do you calculate K factor?

K factor uses the formula K factor = δ/T.

What is K factor in fuel flow?

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.

How do you calculate meter factor?

The meter factor is obtained by dividing the prover test volume by the indicated volume of the meter. Once the meter factor is determined it is used as a volume correction in the calculation for net standard volume of a receipt or delivery of liquids. month, every month the meters are left uncorrected.

What is the difference between K factor and meter factor?

The meter base K-factor is the coarse calibration factor used with the flow computer, which is typically supplied by the meter manufacturer. 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.

What is the value of K factor?

The K-factor comes from the ratio of the neutral radius divided by the thickness of the material on prepared charts and has a value between 0.3 and 0.5. The Y-factor looks at a similar value, but it takes the stresses inherent in the material into consideration, making it more accurate than the K-factor.

What is k factor in flow measurement?

Meter K-Factor is defined as the number of pulses per unit mass or volume at a particular flow rate. Every meter in each turbine contains a K-Factor or a ratio of the pulses per unit of flow. Every time a turbine rotates within a flow rate, the turbine blade passes a face of magnet that creates an electronic pulse.

What is a turbine flow meter?

Turbine flow meter is the most popular equipment to measure flow electronically. They offer a wide flow and application rangeability. Turbine Flow Meters are easy to maintain, durable and versatile.

How do turbine flow meters work?

Turbine flowmeters use the mechanical energy of the fluid to rotate a “pinwheel” (rotor) in the flow stream. Blades on the rotor are angled to transform energy from the flow stream into rotational energy. The rotor shaft spins on bearings.

What is an inline flow meter?

The inline or in-line flow meter includes a flow body that is installed more permanently in a process line. One of the advantages of the in-line meter is that it does not require as much straight run as the insertion-style meter.
