Industrial Flow Equipment Measurement Methods

Industrial flow meters are essential for flow measurements and controlling the flow of liquids, gasses, and slurries in many different industries. It is necessary to use the correct method and the proper flow meters to get accurate flow measurements.

This article will discuss three common methods for measuring industrial flow: volumetric flow rate, mass flow rate, and thermal mass flow rate. We will also discuss how each process works and when it should be used.

Methods used in the flow measurements

Volumetric Flow Rate

The volumetric flow rate is one of the most common flow measurements methods. It measures the amount of liquid, gas, or slurry that passes through a given area in a certain amount of time. 

This method is typically used for liquids and gasses, and it can be used for both laminar and turbulent flow.

To measure volumetric flow rate, you need a flow meter device. There are many different types of flow meters, but the most common type is the orifice plate meter. An orifice plate is a thin metal disk with a hole in the middle.

When liquid or gas passes through the hole, it creates a pressure differential between the front and back of the disk. You can measure the pressure differential to calculate the volumetric flow rate.

Mass Flow Rate

The mass flow rate measures the amount of material that passes through a pipe or duct. It is usually used for slurries and gasses, but it can also be essential for liquids.

To measure mass flow rate, you need a mass flow meter device. There are many different mass flow meters, but the most common type is the Coriolis meter. A Coriolis meter uses the principles of inertia and centrifugal force to calculate the mass flow rate.

Thermal Mass Flow Rate

The thermal mass flow rate measures the amount of heat that passes through a pipe or duct. It is typically used for gasses. However, it can also be suitable for liquids.

You need a thermal mass flow meter device to measure the thermal mass flow rate. There are many different types of thermal mass flow meters.

However, the most common type is the thermal radiation meter. A thermal radiation meter measures the amount of heat radiated from a pipe or duct. This information can be suitable for calculating the thermal mass flow rate.

When to use each method

Volumetric Flow Rate

The volumetric flow rate should be used when you need a precise measurement of the liquid or gas passing through a pipe or duct. This method is beneficial for laminar and turbulent flow.

Mass Flow Rate

The mass flow rate should be used when you need precise flow measurements of the material passing through a pipe or duct. This method is beneficial for slurries and gasses.

Thermal Mass Flow Rate

The thermal mass flow rate should be used when you need a precise measurement of the heat passing through a pipe or duct. This method is beneficial for gasses

Conclusion

Industrial flow meters help in flow measurements using three common methods: volumetric flow rate, mass flow rate, and thermal mass flow rate. Every technique has its advantages and disadvantages, so choosing a suitable plan for the job is essential.
