Select the best flow meter for your application - Bronkhorst

4. How to select the best flow meter for your application?

In this paragraph we will discuss some of the essential elements that go into the decision-making process of selecting a flow measuring instrument. Thereby, we consider the differences between various measurement principles. Read below what to think of when selecting an instrument.

There is a big difference between lab and industrial applications. but most of the considerations are required for both application fields.

Phase of the fluid: gas/liquid/vapour 

Some meters can be easily eliminated because they simply will not work with the application. For instance, electromagnetic flow meters will not work with hydrocarbons and require a conductive liquid to function. Many flow instruments cannot measure vapors or slurries.  

Listed below are some of the main flow meter categories paired with the fluid type the meters can handle: 

• Gas – Coriolis Mass, Thermal Mass, Ultrasonic, Variable Area, Variable Differential Pressure, Positive Displacement, Turbine 
• Liquid – Coriolis Mass, Thermal Mass, Ultrasonic, Variable Differential Pressure, Positive Displacement, Turbine, Electromagnetic 
• Vapour – Vortex, Ultrasonic, Diaphragm, Floating Element

In the world of industrial processes, accurate measurement is paramount. Whether you're managing the flow of liquids or gases in a manufacturing facility, water treatment plant, or any other industrial application, selecting the right flow meter is crucial. The right flow meter can optimise efficiency, ensure product quality and help you meet regulatory requirements. In this article, we'll explore the different types of flow meters and highlight some products from Process Instrument Solutions that can help you make an informed decision for your specific industrial application.

Why Choosing the Right Flow Meter Matters

Flow meters are essential instruments that monitor the rate at which fluids or gases move through a system. They provide vital data for process control, inventory management and quality assurance. Selecting the wrong flow meter can lead to inaccurate measurements, increased energy costs, and potential safety hazards. Therefore, it's essential to understand the various types of flow meters and their suitability for different applications.

Types of Flow Meters

Flow meters come in a variety of types, each designed for specific applications and operating principles. Here are some common types:

Differential Pressure Flow Meters

Mass Flow Meters

Volumetric Flow Meters

Choosing the right flow meter for your industrial application involves several considerations:

Media Type:

• Is the fluid liquid or gas?
• Is it corrosive, abrasive, or conductive?

Rate Range:

• What is the expected flow rate?
• Is the flow rate constant or variable?
• Is a large turndown ratio required?

Accuracy Requirements:

• How precise do your measurements need to be?

Installation and Maintenance:

• What are the installation requirements, and how easy is maintenance?

Environmental Factors:

• Consider factors like Installation and Maintenance.

 Regulatory Considerations:

• Hygienic standards for - 3A & EHEDG
• Environmental & water industry - MCERTS
• Differential pressure flow - ISO5167

Cost Considerations:

• What is your budget for the flow meter?

Choosing the right flow meter for industrial applications is a critical decision that can impact efficiency, safety and cost-effectiveness. By considering factors like the type of fluid, flow rate, accuracy requirements and environmental conditions, you can narrow down your options and make an informed choice.
