Venturi meter, also known as venturi flow meter is a device used to calculate the velocity of fluids in running through a pipeline, it could either be liquid or gas. While an orifice meter is a flat plate having a central hole that is placed across the flow of liquid usually between flanges in a pipeline.
A venturi meter is also called a venturi flowmeter. It is used to calculate the velocity of fluids in running through a pipeline. The fluid may be a liquid or a gas. The meter consists of a pipe with a narrowing throat that expands back to it's original diameter on the other side of the choke point.

Bernoulli Applications A Venturi meter is used to measure the flow rate through a tube. It is based on the use of the Venturi effect, the reduction of fluid pressure that results when a fluid runs through a constricted section of pipe. It is called after Giovanni Battista Venturi (1746-1822),
The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after Giovanni Battista Venturi (1746–1822), an Italian physicist.
Venturi meters are used to measure the speed of a fluid's flow through a pipe. I don't know about in cars, but I think an important industrial application would be to monitor the flow rates of chemicals through the pipes of a chemical plant. I suppose in automobiles it could be used to measure the flow rates of fluids like oil and gasoline.
Applications: It is used where high pressure recovery is required. Can be used for measuring flow rates of water,gases,suspended solids, slurries and dirty liquids. Can be used to measure high flow rates in pipes having diameters in a few meters. Advantages of venturi meters. Less changes of getting clogged with sediments; Coefficient of ...
However, there are few industrial applications in process industries where the standard is perfectly applied. In these cases, calibration of the venturi meter is required under operating conditions. Figure 1: Velocity contours in flow junctions near a venturi flow meter.
Introduction. An Orifice Meter is basically a type of flow meter used to measure the rate of flow of Liquid or Gas, especially Steam, using the Differential Pressure Measurement principle. It is mainly used for robust applications as it is known for its durability and is very economical.
Matching the Flowmeter to the Application ... Venturi: This element finds use primarily in water and wastewater applications. It handles dirty fluids and does not require upstream flow profiling. ...
