To determine the perfect flowmeter, consider essential criteria such as the fluid being measured, the flow range, the accuracy required and the process parameters.
Our detailed guide will help you choose the right flowmeter to optimize your industrial processes and ensure accurate fluid measurement.
In this article, we'll guide you through the process of choosing the right flowmeter for your specific needs.
Whether you are looking for a flowmeter to measure the flow of liquids, gases or steam, we will provide you with all the information you need to make an informed decision.
A flow meter is a measuring device used to determine the quantity of fluid flowing through a pipe. It is essential in many industrial processes, as it allows the flow of fluids to be monitored and controlled.
Now that we've defined the concept of a flowmeter, let's move on to the next question
The choice of flow meter depends on a number of factors, such as the type of fluid, the temperature and pressure conditions of the process, and the characteristics of the application.
Determine the type of flow meter required
Take into account specific parameters
Consider the Installation Requirements
Check out reputable brands
By following these tips, you'll be able to choose the flow meter that best suits your specific needs.
Now that we've covered the basics of choosing a flow meter, let's move on to a more detailed explanation.
Volume flow meters measure the flow rate in terms of the volume of fluid flowing through a pipe for a given period of time.
The differential pressure flowmeter is suitable for measuring the flow of clean liquids and gases, or steam. It uses the differential pressure created by the passage of fluid through an orifice such as an orifice plate or diaphragm.
Differential pressure is measured using pressure transmitters differential and converted into a flow rate.
The venturi flowmeter is used to measure the flow of clean, charged and highly charged liquids, clean gases and charged gases.
It consists of a tapered section of pipe where the fluid velocity increases, enabling the flow rate to be measured as a function of the differential pressure between two measuring points.
The cone flow meter is designed to measure the flow of clean, loaded or highly loaded liquids. It consists of a widening pipe and a cone placed in the middle of the pipe.
The pressure difference between the inlet and outlet of the cone is measured to determine the flow rate.
The pitot tube flow meter is used to measure the flow of clean or slightly contaminated gases and liquids. It consists of a measuring tube placed parallel to the flow in the pipe. The pressure difference between the inlet and outlet of the tube is measured to determine the flow rate.
The main advantage of this type of device is that it does not obstruct the flow in the pipe, allowing higher velocity and greater efficiency to be maintained.

This type of flow meter is suitable for measuring the flow of clean, charged and viscous liquids, as well as clean gases. It uses a float whose position varies according to the flow rate, enabling the volume flowed to be measured.
Gear flow meters are suitable for measuring the flow of clean, charged and viscous liquids, as well as clean gases. They use a pair of rotating gears to measure the volume of flowing fluid.
This type of electromagnetic flow meter is suitable for measuring the flow rate of clean, charged, viscous and conductive liquids.
The electromagnetic flow meter uses a magnetic field to induce an electromotive force proportional to the fluid's flow velocity, enabling the volume flow rate to be measured.
The vortex flow meter is suitable for measuring the flow of clean, charged liquids and clean gases. It uses vortices generated by the fluid flow to measure flow.
This type of non-intrusive flow meter is used to measure the flow of clean liquids.
It works on non-conductive fluids. It uses ultrasonic waves to measure the transit time of the fluid, enabling the flow rate to be calculated.
The latest generation of ultrasonic flowmeters can also measure saturated steam flow. These flowmeters are also available in a portable version. They enable uninterrupted flow measurement.
Mass flow meters measure the flow rate in terms of the mass of fluid flowing through a pipe over a given period of time. The most commonly used types of mass flow meters are:
The Coriolis flow meter is suitable for measuring the flow of clean, charged, highly charged, multiphase liquids, clean gases and charged gases. It measures flow by detecting the deflection resulting from Coriolis forces as a fluid flows through a vibrating tube.
Thermal mass flow meters are suitable for measuring the flow of clean liquids, clean gases and charged gases. They measure flow by detecting the heat transfer caused by the flow of the fluid.
In-line ultrasonic flow meters are used to measure gases such as air or nitrogen. They feature pressure and temperature correction to display the mass flow rate.
Now that you have an overview of the different types of flow meter and their principles, let's explore in more detail the parameters to consider when choosing a flow meter.
When choosing a flow meter, it is essential to consider a number of parameters to ensure that it is suitable for your specific application. Here are the main parameters to consider:
Type of fluid
Temperature and pressure conditions
Pressure losses
Need flow information
Installation features
By taking these parameters into account, you will be able to choose the flow meter that best meets your specific needs.
Here's everything you need to know to make the right choice of flow meter. Don't hesitate to consult reputable brands and seek professional advice if necessary. The right flow meter will ensure accurate and reliable flow measurement in your application.
There are several well-known brands in the flow meter field. Popular brands include Fuji Electric, Endress+Hauser, Yokogawa, Emerson, Siemens, Krohne, and ABB.
There is no single answer to this question, as the choice of flow meter depends on the specific application. However, electromagnetic, ultrasonic and coriolis flow meters are widely used in many industries because of their versatility and accuracy.
The flow rate in a pipe can be measured using an appropriate flow meter. The flow meter is installed in the pipe and measures the flow rate of the fluid passing through it using different measurement technologies.
The ideal conditions for measuring flow depend on the type of flow meter used. However, in general, stable temperature and pressure conditions, regular pipework without excessive disturbance and a clean fluid are conducive to accurate flow measurement.
Flow measurement is essential in industrial processes because it enables the flow of fluids to be controlled and monitored. This ensures that processes run efficiently and enables problems or undesirable variations in flow to be detected quickly.
Mass flow meters measure flow in terms of the mass of fluid flowing through them, making them independent of variations in fluid density. This makes them particularly suitable for applications where fluid density can vary.
We hope this article has provided you with the information you need to understand the different types of flow meter and their principles, thus to choose the right flow meter for your application.
The flow meter is an essential tool for measuring and controlling fluid flow rates in various industrial applications. Thanks to its advanced features, it ensures accurate measurement and optimal management of your processes.
