 How does a Flow meter work? 

A flow gauge is a crucial device that measures the rate of flow of substances like air, water, and gas. Understanding its functioning is essential for accurate measurements. Here's how a flow gauge works:

• Flow gauges utilise various principles like differential pressure, thermal, or ultrasonic to measure flow rates.

• For example, in a differential pressure flow gauge, the pressure difference across an obstruction is measured to calculate the flow.

• Thermal flow gauges use the cooling effect of the flowing fluid to determine the flow rate.

• Ultrasonic flow gauges employ sound waves to measure the speed of the fluid.

• Coriolis flow gauges employ the principle of measuring the deflection caused by fluid flow to determine the flow rate accurately.

• Turbine flow gauges utilise a rotating turbine placed in the fluid stream, and the rotation speed correlates to the flow rate.

• Magnetic flow gauges use electromagnetic induction to measure the flow rate by detecting the voltage generated as the conductive fluid passes through a magnetic field.

• Vortex flow gauges create vortices in the fluid flow, and the frequency of these vortices is proportional to the flow rate.

• Positive displacement flow gauges measure the fluid flow by capturing and measuring discrete volumes of the fluid passing through the meter.
