How does orifice plate measure flow?
How does orifice plate measure flow?
When an orifice plate is placed in a pipe carrying the fluid whose rate of flow is to be measured, the orifice plate causes a pressure drop which varies with the flow rate. This pressure drop is measured using a differential pressure transmitter and can be used to calculate the flow rate.
How does an orifice plate work?
The small hole on orifice plates restricts flow which causes the pressure to drop. The pressurecan be measured using pressure gauges before and after the orifice plates whichallows you to determine the flow rate using the Bernoulli’s Equation.
What is Venturimeter and orifice plate?
Venturi meter and orifice meter are used for measuring the volumetric flow rate of the fluid that based on the continuity equation and Bernoulli’s equation. Whereas the orifice meter consists of a thin plate and a bore. The pressure loss in venturi meter is 10% while in the orifice meter the pressure loss is 50-60%.
Does orifice reduce flow?
A reduction in orifice size results in decreased flow as only so much liquid can pass through the orifice. Since the flow of liquid is limited by the orifice, it follows that the pressure on the exit side of the orifice is less than that on the inlet side.
What is the purpose of an orifice plate?
According to Michael Reader-Harris (n.d) Orifice plate is an instrument use for three different applications one to measure the flow rate, second to restricting the flow and third is to reduce the pressure of the flowing fluid.

What is the effect of Venturi meter and orifice plate?
In this post the effect of venturi meter and orifice plate on the fluid flow will be disciussed and complete work will be presented in the form of report. The aim of this experiment is to study the overall meter coefficient C of Venture meter and Orifice plate
Is there an alternative to an orifice plate flow meter?
Although Omega Engineering does not carry this exact product, we do have alternatives. In this case, the proper alternative is heavily reliant on the application. As flow technology has become more affordable, other technologies are more practical and accurate than an orifice flow meter.
