Venturimeter: A venturimeter is a flow-measuring device with

A venturimeter is a flow-measuring device with a narrow throat to convert potential energy from the fluid flowing through the pipe, on which these devices are installed, to kinetic energy and measures the flow rate. It works on Bernoulli’s principle. Learn what a venturimeter is, how it works, and how to calculate the flow rate of a fluid using Bernoulli's equation. See the main parts, construction, advantages, disadvantages, and applications of venturimeters. When venturi flow meter is placed in a pipe carrying the fluid whose flow rate is to be measured, a pressure drop occurs across venturi meter . Venturimeter is a flow measurement device, which is based on the principle of Bernoulli's equation. Inside the pipe pressure difference is created by reducing the cross-sectional area of the flow passage. This difference in pressure is measured with the help of manometer and helps in determining rate of fluid flow or other discharge from the pipe line. Venturimeter has a cylindrical entrance section, converging conical inlet, a cylindrical throat and a diverging recovery cone. Components of ...
