Venturi Meter Reading, Calibration Of Venturi And Orifice Meters

In the venturi meter the fluid is accelerated through a converging cone of angle 15 20 o and the pressure difference between the upstream side of the cone and the throat is measured and provides a signal for the rate of flow.

Greece super league winner odds. This is widely used for a high flow rate discharge. The cv venturi flow meter is a differential pressure element de signed to accurately measure the ow of liquids and gases by forcing the flow into a smaller diameter section of pipe then measuring the pressure differences between the unrestricted ow and the restricted ow. Venturi flow meters can be used to measure the actual gas flow rate in wet gas streams provided the liquid content is known.

The classical venturi meter whose use is described in iso 5167 1. Venturi tubes which are constrictions or throats in fluid conduits are regions of reduced pressure that are used in a number of devices. Take the six readings.

Repeat the same procedure for orifice meter. The area of cross sections of pipe at ends where the venturi meter has been connected are a 1 and a 2 respectively. Tanner in physics for students of science and engineering 1985.

Traditional venturi meters read the inlet pressure p1 the downstream temperature t and the differential pressure. The installation cost of a venturi meter is high. Prove that for any flow the reading is unaffected by the slope of the meter.

Classical vetituri meter design. An empirical correlation is presented which accurately predicts the effect of the liquid phase on venturi meter readings in wet gas horizontal flow. E 913 calculate the flow speed that corresponds to a venturi meter reading of h 12 cm if r o r 136 and aa o 30.

Disadvantages of venturi meter. 314 with permission of bsi for incompressible flow if the bernoulli equation is applied between two planes of the tappings. There are little difficulties while maintenance.

The correlation is based on a comprehensive experimental. Venturi meter with instrumentation sketch and pressure fluctuation graph figure 1 shows a venturi meter with instrumentation sketch and the simplified pressure fluctuation through the meter body. The corresponding velocity of fluid are v 1 and v 2.

The coefficient of discharge cd for the venturi meter is high. The venturi meter is connected to a pipe at two points as shown in the fig. Although there are few disadvantages of venturi meter and those are.
