1.VENTURIMETER
*It is an instrument used to measure the rate of discharge in a pipeline.
*Venturimeter works under the principle of Bernoulli's equation and Continuity equation.
*It consist of three parts
i)converging part
ii)Diverging part
iii)Throat
Types of Venturimeter
1.Horizontal Venturimeter
2.Vertical Venturimeter
3.Inclined Venturimeter
2.ORIFICE METER
*Orifice meter (or) orifice plate is a device employed for measuring the discharge of fluid through a pipe
3.PITOT TUBE
Pitot tube is one of the most accurate devices for velocity measurement.
4.ROTOMETER
A rotameter is a device that measures the volumetric flow rate of fluid in a closed tube. It belongs to a class of meters called variable area meters, which measure flow rate by allowing the cross-sectional area the fluid travels through to vary, causing a measurable effect.
5.ELBOW METER
Pipe elbow used as a liquids flowmeter; flow rate is measured by determining the differential pressure developed betweenthe inner and outer radii of the bend by means of two pressure taps located midway on the bend.
