Flow Measurement Devices: Everything You Need to Know

Thermal, Coriolis, or Vortex —Which one is Best for You?

 

It is important to learn how to properly select a flow monitoring device for any scenario. Issues that affect flow meters or sensors can result in product quality and performance decrease. In turn, this may lead to damage to the machine tools. This will only lead to time-consuming maintenance and repairs. It is highly likely that this will result in not only added costs but lost opportunities as well.

 

Flow Measurement Devices —What Are They For?

Precision flow meters are used to provide reliable monitoring and flow control. Some industrial applications require the precise calculation of quantity. Applications can range from precision servo-valve development to measuring water flow —from responding to a need from the aerospace industry to a vineyard measurement accuracy requirement of 5%.

So which meter do you need? Let’s find out.

A thermal mass flow meter is ideally used for natural gas, low-pressure drop, and natural gas thermal mass flow meter for boilers. It measures any inert gas and non-condensing clean gas as well as flammable gases such as methane, propane, digester gas, and natural gas.

 

This Tactical Flow Meter boasts a power fail tolerant datalog storage system that is a significant improvement over conventional "SD Card" file storage systems.

Coriolis mass flow meters produce the most accurate measurement for most liquids. Although they can be quite expensive, they have the advantage of not needing any knowledge about the fluid being carried based on the principles of motion mechanics.

Vortex Flow Meter

Vortex flow meters measure fluid velocity using a principle called the von Kármán effect. The von Kármán effect states that when flow passes by a bluff body, a repeating pattern of swirling vortices is made. Multivariable Vortex Flow Meters also hold a huge advantage over Thermal Mass Flow Meters as long as they don’t need to measure ultra-low or ultra-high flows.

  

Today, Vortex and Coriolis flowmeters are commonly used for a wide variety of applications. There are a lot of options in flowmeters but there are distinct differences in functionality, accuracy, and of course —price. It’s always a good idea to conduct your research first before bringing out the big bucks.
