venturi flow meter diagram

The direction of flow in the venturi meter should be checked and set up to agree the flow direction. It is that portion of the venturi where the fluid gets converges.

Definition and different parts of a venturimeter.

. To determine the flow rate. Calculating the flow rate of fluid that is discharged through the pipe. Experimental Set Up A schematic diagram of the plastic pipe Venturi meter is shown in figure 3.

Measuring the rate of flow of liquid is essential many times and this simple device is widely used to do it precisely. Straight Pipe Diameters same line size as Venturi Flow Flow 2 5 FIRE PUMP A OSY Valve To System Optional to Pump Inlet Supply from City Main or Reservoir TO RESERVOIR OR WASTE OSY or Indicating Butterfly Bypass Valve. The change in pressure in the fluid as it passes through the meter can be used.

It is the portion that. The wiring diagram for all of the components is shown below followed by a table of pinout connections. Diagram of the working principle of.

The venturi meter given in the kit above has an inner inlet diameter of 76mm and an inner throat diameter of 57mm. A schematic of the Venturi meter is shown on the diagram at the end of the procedure. It is a cheaper device as compared to venturimeter.

When a venturi flow meter is placed in a pipe carrying the fluid whose flow rate is to be measured a pressure drop occurs between the entrance and throat of the venturi meter. Venturi Meter1 Water Supply Flow meter Stop watch Calculator B. Italian scientist Giovanni B Venturi 1746-1822.

It consists of flat circular plate which has a circular hole in concentric with the pipe. A venturimeter is a device used for measuring the rate of flow of a fluid flowing through a pipe. Venturimeter-device used for measuring the rate of flow of a fluid flowing through a pipe It consists of three parts.

A venturi creates a constriction within a pipe classically an hourglass shape that varies the flow characteristics of a fluid either liquid or gas travelling through the tube. A venturi tube contains a throat which is smaller in a diameter to the pipeline into which it fits. 1Definition of Venturimeter 2Parts of a Venturimeter 3Principle involved in it 4Expression for rate of flow 5.

Advantages and Disadvantages of Venturimeter. Equations for Venturi Flow Meter Top of Page The calculations on this page are for a Classical Venturi Tube carrying a liquid as described in ISO 1991 and in ASME 1971. Generally the following guidelines should be followed when installing venturi meters.

Venturimeter Principle Construction and Working with Diagram Read More. As the fluid velocity in the throat is increased there is a consequential drop in pressure. In the industrial sector it is used to determine the pressure as well of the quantity of gas and liquid inside a pipe.

Venturi Flow Meter. Venturi tubes which are constrictions or throats in fluid conduits are regions of reduced pressure that are used in a number of devices. EXPERIMENT TO STUDY FLOW THROUGH A VENTURI METER.

Venturi Meter or Venturimeter or Venturi Tube a well-known device in fluid mechanics that uses venturi effects. Venturi Meter Constructions for Plastic Irrigation Pipelines. A DP transmitter converts the differential pressure created by a venturi into an electrical signal that can be used for monitoring and controlling the flow rate.

The inlet diameter equals d 26 mm and the throat diameter d 16 mm. Idealized flow in a Venturi tube. These values will be used later to approximate flow rate and velocity in the venturi meter.

The Venturi effect is named after its discoverer the 18th century Italian physicist Giovanni Battista Venturi. Diagram of typical elbow meter venturi type. The Venturimeter is used to measure the flow rate of compressible and incompressible fluid through a pipeline.

The ISO reference has a more complete discussion of venturi tubes than the ASME reference so the ISO equations are used in our calculations. Part 2 - Part 20 in a series of tutorials in instrumentation and measurement. Procedure Let us first define the Venturi Meter and the way it works in order to proceed in the experiment.

DIAGRAM GERAND GPM METER - VENTURI PACKAGE B - Butterfly Throttle Valve Air Vent Min. The meter in its. Applications of Venturi Meter.

A short converging part. Venturi Meter is used in various field like. Tanner in Physics for Students of Science and Engineering 1985 E 913.

The pressure along the meter is obtained using the 11 pressure taps at the locations shown on the diagram. Therefore venturimeters should be installed following the manufacturers guidelines. The flow of chemicals in pipelines.

The final consideration when installing a venturi flow meter is the connection between the venturi and the differential pressure DP transmitter. 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 system consists of a pipe of several meters plumbed in series.

Inside the flow bench a tank is connected to one end of a lever arm. This pressure drop is measured using a differential pressure sensor and when calibrated this pressure drop becomes a measure of flow rate. Calculate the flow speed that corresponds to a Venturi-meter reading of h 12 cm if ρ o ρ 136 and AA o 30.

Fig 11 Venturi Meter Diagram. Main parts of Venturimeter The main parts of a venturimeter are. Venturi flow meters offer high accuracy and reliability for flow measurement of pressurized line fluids including liquids gases and steam as well as high-viscosity line fluids solids-bearing line fluids and harsh or contaminated line fluids.

The experimental setup is shown in Figure 1. Orifice meter Orifice meter. Installing a proper venturi meter is the solution to correct operation.

The apparatus consists of a flow bench from where water can flow to the venture meter. There is an inlet water valve an air pipe operated water flow control valve a magnetic inductive flowmeter a turbine flowmeter a rotameter an ultrasonic flowmeter an orifice meter and a venturi meter. The water flow rate can be adjusted using the valves on the hydraulics bench.

I Converging part ii Throat iii. Video of a Venturi meter used in a lab experiment. The water that exits.

This also work on the same principle as that of venturimeter. The restriction diameter should not be less than 0224 D and not more than 0742 D where D is the nominal bore diameter of the pipe. FLUIDS MECHANICS1 4.

Is a device used for measuring the rate of flow of a fluid flowing through a pipe.
