Flow measurement identifies the quantity of the fluid that passes through any pipe, channel, or space using flow measurement devices. Fluids that are measured include liquids, gas, or vapor.
To measure the flow of any fluid, there is a need for some device or instrument, and the device used to measure the flow is known as a flow measurement device.
A flow measurement device commonly referred to as a flowmeter is an instrument that is used to measure the flow rate of a fluid per unit time (Volume or mass of the given fluid.)
Ways of Flow Measurement
As mentioned above, flow is measured in two ways: in volume or mass per unit of time.
1. Volume Flow
The volumetric flow of a substance is defined as the measurement of the volume quantity that flows/passes through a given area or section per unit of time.
2. Mass Flow
The mass flow of a substance is defined as the measurement of the mass quantity that passes or flows through a given area or section per unit of time.
Why Is Flow Measurement Important?
In industries, flow measurement is important as it determines the functioning of your system. This means if the system in your industry where flow processes are occurring is functioning well, they will produce highly accurate results. Hence, the more accurate the results of your flow measurement, the more accurate is your system's functioning.
Flow measurement is crucial to monitor, control, and keep a check on the rate of fluid that is flowing through a channel or section. The flow measurement process measures the flow of a wide range of liquids, including heavy oils, light gases, spirits, chemicals, water or food.
Flow measurement is critical where the fluid needs to be used regularly. This assures that the flow rate of fluid passing is accurate. It also assures that the right fluid is being processed in the right place and at the right time. This helps to reveal the fluid quality as well.
The accurate measurement of the liquid fluid flow is particularly important where critical applications are taking place in the industry because a little error can lead to a huge loss.
