Of all types of flow meters available in their market today, vortex flow meters have proved to be the most versatile. The reason being that they are used to measure different types of fluids, including wastewater treatment and industrial chemicals. However, these essential flow meters also have their flaws. This has pushed suppliers to work extra hard to look into ways of stopping limitations found in vortex flow meters. Currently, they have introduced advanced versions of vortex flow meters that can measure flow rate more efficiently and accurately.
In this article, we will look into the various advancements of vortex flow meters that have made them more reliable. Some of the new features of vortex flow meters include:
- Advanced filtering algorithms – This feature is meant to establish continuous, real-time norms for quality and signal strength. The feature is also used to minimize the common mode noise effects and other noise-related equipment vibration in pipes while working.
- Rugged One-piece Welded Sensor Designs – This nifty feature of a rugged sensor is designed to get rid of reading errors and failures brought about by leaks in the flow meters’ lifetime.
- Dual-sensor Technology – This is an innovative technology that comes with a feature to enhance the signal frequency.
Vortex flow meters can measure the velocity of fluids such as water, cryogenic fluids, chemicals, nitrogen, hydrocarbons, boiler feed water, and air. Vortex flow meters are also used to measure industrial steam and gasses that pass through pipes. Their tolerance to very high temperatures and liquid droplets is what makes vortex flow meters ideal instruments for measuring wet gases and saturated steam.
Benefits of using a Vortex Meter
- Repeatability of +/- quarter percent of flow rate
- Has a ride rangeability
- Accuracy of +/- 1 percent of flow rate
- The vortex flowmeter comes in several designs and sizes
- Quite reliable when measuring liquids, steam, and gases
- It offers a linear output
- Analog, pulse, and bus outputs
As much as vortex flow meters are quite versatile, they have a few setbacks. One of their cons is that you can’t use them with slurry substances or liquids with high viscosity. They also won’t produce accurate flow rate measurements when there is a very low flow rate. When the flow rate is too low, vortices don’t form. For vortex flow meters to work efficiently, turbulent flow needs to be present. There may be a need for strainers also. Extreme turbulence or pulsating flow may affect the flow meter’s performance.
Latest Design Enhancement of Vortex Flow Meters
For decades, flow meters that use the vortex shedding principle have been used. Meaning that these flow measurement instruments were not just invented the other day. However, the design used ten years ago is not the same one used today. There have been several advancements made. Vortex flowmeters are now popularly used in industrial flow measurement due to the electronic and signal processing improvements made a couple of years back. Changes have also been made in the interaction between the bluff body and the sensing system to make it more efficient.
For a more precise mass flow measurement, the modern vortex flow meter is fitted with an internal resistance temperature detector (RTD). This allows it to compensate for temperature changes in the flowing substance that is being measured. Modern vortex flow meters come with piezoelectric crystal sensors for detecting the pressure exerted by the vortices. The detector converts the pulses into electrical signals, then converted by the meter electronics into a frequency. This process makes it easier for the vortex flowmeter to provide a volumetric flow rate.
When you need to get accurate readings when measuring flow rate, you need to use proper flow meters. The vortex flowmeter has come a long way since it was invented. Several advancements have been made to make it more efficient when measuring several kinds of substances. Look for a reliable vortex flow meter vendor to get the best out of these measurement instruments.
