Different Types of Flow Meters Used for Industrial Uses

In measuring the flow of fluids in terms of volume or mass, special devices are used. These devices are called liquid flow meters. Flow meters are essential devices for liquid flow measurement. And since many types of fluids require measuring, finding the right type of water flow sensor is important to get value from your investment. There are flow meters meant for domestic use, and we also have flow meters designed for industrial use. Industrial liquid flow meters cater for larger productivity to give estimates of losses or profit gained. 

In this post, we will give you the various types of industrial fluid flow meters and their use. With this knowledge, you can choose the right flow meter in any application you have. Read on to get a better understanding. Liquid flow meters go by several names based on the industry. These names include flow gauges, flow indicators, flow rate sensors, liquid meters, etc. For most flow meters, measurement is done by directing fluid in a confined space. This allows the user to check different fluid properties to know its measurement. 

The type of fluid flow meter depends on the application because each is designed to work optimally under different conditions. As the user, you must first understand your application’s needs before picking one. Before selecting a water flow sensor to use in your application, these are the questions you need to ask yourself first. 

  • What is the fluid temperature that needs to be measured? 
  • What type of fluid do you need to measure? 
  • What is the accuracy level required? 
  • What is the max and min pressure expected where you are going to install the water flow meter? 
  • Is the measured fluid flowing continuously, or is it sporadic? 
  • What pipe size do you intend to use in your application? 

Now that you know what you need when looking for a flow meter, let’s now look at the various types of industrial flow meters. 

Types of Flow Meters Used in Industries 

Differential Pressure Flow Meters

Differential pressure meters are largely used in the oil and gas industries. When measuring the flow of fluids, a cross-sectional area of a flowing fluid is restricted. A differential pressure flow meter is ideal if moving parts in a water flow meter are not needed, and there is a need for quick response. In the fuel industry, these flow meters are used to calculate the fuel output, plain water flow testing, and special chemical flow. You can also find them in labs and are used to measure the controlled flow of gases. A process called chromatography is used to mix and separate gases in labs. When using differential flow meters, users must check the pipe’s size, flow condition, and the fluid’s nature. Differential pressure meters come in different types. They include:

  • Flow Tubes
  • Elbow-Tap Meters
  • Orifices
  • Target Meters
  • Venturi Tubes
  • Flow Nozzles
  • Rotameters
  • Variable-Area Meters

Positive Displacement Flow Meters

Positive displacement flow meters are also known as PD flow meters, and they are the only type of flow meters that the flow volume of liquids that pass directly through the pipe. These types of flow meters are perfect for measuring the flow of paints, petrochemical, and adhesives. The benefits of PD flow meters include high accuracy, durability, low-pressure drop, and low operation cost. These flowmeters have high accuracy no matter the viscosity, velocity, density, or temperature of the liquid. Because they are easy to install, use, and maintain, they are commonly used in domestic water measurement. PD flowmeters include:

  • Rotary Vane Meters
  • Reciprocating Piston
  • Oval Gear
  • Nutating Disk Flow Meters


In various industries that deal with fluids, flow meters are very useful. However, a water flow meter‘s accuracy and efficiency depend on matching the proper flow meters with the right application. Using the right flow meter with the right application will give you a significant return on investment. If you are not sure, consult first with the manufacturer before buying.
