Mechanical flow meters have stood the test of time since their inception in the 18th century. Their reliability and efficiency in measuring fluid flow continue to be valued across various industries. Over the years, advancements in fluid flow measurement techniques, such as Daniel's use of differential pressure and Venturi's examination of the Venturi tube, have contributed to their sustained popularity.

Types of Mechanical Flow Meters

Mechanical flow meters utilize moving parts like gears or turbines to measure fluid flow, encompassing various types [2] tailored for specific applications:

Turbine Flow Meters:

These employ rotating turbines to measure flow rates in water, chemicals, and fuels as shown in the image. However, they might face accuracy challenges at low flow rates and high-velocity operation.

Positive Displacement Flow Meters

Known for accuracy and reliability, these excel in measuring viscous liquids like oils but might not be ideal for water measurement.

Rotameter or Variable Area Flow Meters

Equipped with tapered tubes and a float mechanism, they offer versatile readings for gases and liquids but might come with drawbacks like high cost and limited accuracy with incompatible fluids.
