How does a vortex flowmeter work?

How does a vortex flowmeter 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 do you size a vortex flow meter?

vortex is way oversized for your application. Normal rule of thumb for vortex flowmeter sizing is at least one line size smaller than the pipe size for most applications. Looking at your requirements, a 1.5 in. vortex would actually give the best results because it has an approximately 0.95 to 34 m³/hr range.

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.

Why we use vortex flow meter?

Vortex flowmeters are used in numerous branches of industry to measure the volume flow of liquids, gases and steam.

How do you troubleshoot a vortex flow meter?

Question 1: The vortex flowmeter has no display 1), Power Supply Failure/Power is Not Wired: Test the voltage on the power source with a universal meter; 2), Cable is Broken: Check for a break off point on the cable; 3), Wrong Wiring: Check if wired to the correct terminal.

How do you calibrate a vortex flow meter?

Calibration of Vortex Flow Transmitters:

  1. Set frequency generator at upper range value, and adjust fine span screw till you reach 100% value.
  2. Disconnect the frequency generator and connect the signal lead.
  3. Adjust zero, till input and output matches.

Who invented vortex flow meter?

Theodore von Karman, a Hungarian-American physicist, was the first to describe the effect where a non-streamlined object (also called a bluff body) placed in the path of a fast-flowing stream, causes the fluid to alternately separate from the object on its two downstream sides, and, as the boundary layer becomes …
