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.
How do you calculate K-factor?
K factor is a ratio between the distance from the neutral bend line to the inside bend radius and the material thickness. K factor uses the formula K factor = δ/T. Y factor uses the formula Y factor = K factor * (Π/2).
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 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 flow meter?
W = r · Q, which means that the mass flow of fluid passing through a flowmeter (A) is equal to the fluid density (r) times the volume of the fluid (Q). Volumetric flowmeters directly measure the volume of fluid (Q) passing through the flowmeter.
What is the standard K factor?
The K-factor is usually somewhere between 0.3 and 0.5.
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.
What is K-factor calibration?
What is K-factor in oil and gas?
The k factor is a calculation that shows how quickly a home is consuming the fuel it uses to produce heat. The k-factor calculation can be used in homes that use all types of combustible fuel, from natural gas to propane to heating oil. A home’s k factor represents the number of gallons of fuel burned per degree day.
What is turbine flow meter?
Turbine Flow Meter Overview: A turbine flow meter is a volume sensing device. As liquid or gas passes through the turbine housing, it causes the freely suspended turbine blades to rotate. The velocity of the turbine rotor is directly proportional to the velocity of the fluid passing through the flow meter.
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.
