Flow meter important tool for measure the liquid flow

Author: Nehmat Sandhu

There are various parameters which influence the selection of the flow meter for different applications. When selecting a meter, it is important to consider flow meter as per your specific use. Consider a variety of factors ranging from your knowledge and the properties of the flow meter to the condition of the volume of fluids, use, fluid properties.

Purpose and application: Know what task you want to accomplish with a flow meter and what is your job requirements and application type. In addition to these, it is also important to know the category of the flow of liquid and gases. It will help you to define which type of flow meter will be best suited to your work environment.

Flow profiles of the meter: know what the characteristics are and flow rates of the gases or liquid for your job applications. Do you know the minimum and maximum flow rates of the application? What do you know about the performance qualities of the flow meter? Profile of the flow meter determines the momentum and different behaviors of the fluid. Newtonian fluids and non-Newtonian fluids have a different flow rate, viscosity, velocity and pressure that support the flow rates. Also be cautious about these attributes to find the correct flow meter as per your requirements.

Performance and capabilities: the behavior of the flow meter is determined by the Reynolds number. It has a dimensionless quantity that explains the relationship between velocity and momentum of the fluid that defines that stream or flow is turbulent or laminar. It helps with the chemical capability, temperature, fluid pressure that will assist you in identifying the performance capability and accuracy of the flow meter for different gases or liquid application.

External factors: There are various environmental conditions and factors that are beyond your control and affect the functioning. Factors related to installation and general lifespan of the flow meter also weigh your flow meter decision-making process.

Budget- You should plan for the cost of the meter for preventive maintenance, installation, repair, running cost of flow meter during the decision-making process.

Selection of the meter depends upon your requirement and functions. There are various types of meters on the market that you can choose from.
