Does a vortex need to be calibrated?
It is very unusual that a vortex flowmeter will require re-calibration for shedder bar wear in normal applications. (Vortex meters count the frequency of shedding which is proportional to the fluid velocity – and is not highly sensitive to edge sharpness).
How do you calibrate a vortex?
Calibration Process
- Download and install the Tacx Utility app from your phone or tablet’s app store.
- Open the app and select (upper left)
- Select Calibration.
- Select CALIBRATE YOUR TRAINER.
- Follow the app on-screen instructions to complete the process.
Do flow meters require calibration?
Every so often flow meters need to be calibrated, meaning their performance must be compared to a standard, and the meter’s deviation from that standard must be determined and corrected.
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.
How do you calibrate a steam flow meter?
To perform Master meter calibration:
- Place the master meter in series with the flow meter under test.
- Compare the readings of the master flow meter and flow meter using a measured volume of liquid.
- Calibrate the flowmeter under test to conform with the master flow meter calibration.
How does a vortex shedding flow meter work?
A vortex flow meter is a flow measurement device best suited for flow measurements where the introduction of moving parts presents problems. Vortex flow meters operate under the vortex shedding principle, where an oscillating vortexes occur when a fluid such as water flow past a bluff (as opposed to streamlined) body.
How is a flow meter calibrated?
Flow meters are calibrated by comparing and adjusting their metering to correspond with a predefined standard. Flow meter manufacturers typically calibrate their products in-house after production or send them to an independent calibration facility for adjustment.
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 working principle of vortex flowmeter?
Vortex Flowmeter works on the principle of Karman Vortex Street. Any medium passing through the pipeline flows around the bluff body and sheds a series of alternating vortices on each side of the body. This phenomenon is known as Vortex Shedding. These vortices shed downstream of the bluff body and dissipate as they flow further.

How does the vortex flowmeter work?
Vortex flow meters operate under the vortex shedding principle, where an oscillating vortexes occur when a fluid such as water flow past a bluff (as opposed to streamlined) body. The frequency that the vortexes are shed depend on the size and shape of the body.
How does vortex flowmeters work?
Vortex flow meters measure fluid velocity using a principle of operation referred to as the von Kármán effect , which states that when flow passes by a bluff body, a repeating pattern of swirling vortices is generated. In a Vortex flow meter, an obstruction in the flow path, often referred to as a shedder bar, serves as the bluff body.
