Flow meter k factor

Turbine Flow meter Scaling Factor. The Meter Factor of a meter factor used with a meter to correct accuracy for ambient conditions.

Example 1 If the display on a rate meter is required in US.

Flow meter k factor. What is the K-factor in a flow meter. K-factor is a coefficient calculated by calibrating and comparing with other measuring devices that meet the accuracy requirements. The Flow Meter K-factor will be confirmed before it is put into use.

This coefficient is a fixed value. The calibration certificate will show that the meter has been calibrated over its flow range and noted on the certificate will be the average K-factor for the meter. This K-factor will be given in terms of the number of pulses produced by the meter for a given volumetric flow.

Eg 200 pulses per US. Gallon 150 pulses per liter etc. Coriolis flowmeters do not have a fixed K-factor number of pulses output per unit of flow.

The number of pulses output per unit of flow eg. Pulses per barrel from a Coriolis meter is instead an adjustable parameter that can be set to any desired value within the range of. This K-factor is the value that is entered into a batch meter or indicatortotalizer in order to give a readout in engineering units.

Example 1 If the display on a rate meter is required in US. Gallons per second and the K-factor of the flow meter is 210 pulses per US. Gallon then the K-factor entered into the rate meter would be 210.

If a totalizer associated with the same flow meter was to be set up so as. Abbreviation of calibration factor of vortex flow meter The base of Vortex flow meter is based of von karmen vortex street principle as per which if a shedder bar designed properly then strouhal number will be constant for wide range of Reynolds No in below equation. 10 rows K-factor Calculator.

Choose Meter Type EX810EX820 EX110. K is the a constant for all fluids given design of meter. A k factor is introduced to compensate for the non-uniform profile of pipe flow.

S is the Strouhal number determined experimentally. Type of Fitting K Value Disk or Wobble Meter 34 - 10 Rotary Meter Star or Cog-Wheel Piston 10 Reciprocating Piston Meter 15 Turbine Wheel Double-Flow Meter 5 - 75 Bends wCorrugated Inner Radius 13 - 16 times value for smooth bend Example. Determine L friction loss in pipe fittings in terms of equivalent length in feet of straight pipe.

The meter coefficient is as follows. K Pulses Volume. So as per above inputs K 10 Pulses gallon.

The scaling factor is as follows. 10 pulsesgallon x 100 gallons 1000 pulses. The K-factor is the frequency divided by the flow rate 1s gs 1g.

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. Calculating and Using K-Factors.

And the K-factor of the flow meter is 210 pulses per US. The first step is to calculate K-factors to cover each flow range. The K-Factor Pulses per unit volume of a meter.

The Meter Factor of a meter factor used with a meter to correct accuracy for ambient conditions. The Linearity over the calibrated flow range for the meter. The Repeatability for the meter system.

The meter factor is obtained by dividing the prover test volume by the indicated volume of the meter. Once the meter factor is. The k-factor is dependent upon the orifice diameter of the sprinkler - a low k-factor such as K28 restricts the flow of water while a larger k-factor such as K224 K252 or K280 permit much more water to flow through.

K-factors were originally created to be. Determine the number of pulses generated by GF Signet flow sensors. K-Factors are calibration values pulses per unit of volume used to convert flow sensor output frequencies to flow rates.

This calculation tool helps you to determine the correct K-Factor for your flow sensor. K-factor aeronautics 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. Flow Meters and Environmental Sensors for Precision Fluid Measurement.

Find a Distributor Contact Us 800-975-8153. This K-Factor is unique to each and every Turbine Flow Meter and is determined by the manufacturer. As we discussed earlier the Turbine Flow Meter will generate pulses and the pulse rate depends upon the fluid velocity.

The unique K-Factor declares the number of pulses that will be generated for every unit of product passing through it. In this tutorial will set the Flow rate K-factor for volumetric US Gal and the Total K-factor for mass flow measurement in kgs. Like it is used in weighing.

In this tutorial we will set the K-factor for mass flow measurement with automatic conversion and configure the settings to display the Total and Flow rate. The K factor is a proportionality factor required for conversion with correct quantities between the signal of the measuring sensor and the real process value. Christian Bürkert GmbH Co.
