Difference between orificemeter and venturimeter

Want to know about the Difference between orificemeter and venturimeter?

Then you are on the right path. Here you will know the detailed comparison between these two devices.

So, I invite you to come with me and feel comfortable while I start the engine of this knowledgeable journey here at Engineers Rail.

So, Without further delay, Let’s dive in.

Before jumping in the title of the article, It would be nice to know about these devices briefly.

So, here we go…

What is an Orifice meter?

Basically, an Orifice meter is referred as a type of flow meter that uses differential pressure measurement techniques and this helps to get discharge rate as well as calculate the flow rate.

In short, Orifice meters is a device to measure the flow rate or discharge rate of any fluid. Oficemeter is used mainly in robust applications and an Orifice meter works based on the differential measurement technique.

What is Venturimeter?

Volumatricmeter is the discharge measuring device and it measures volumetric flow.

Here, You may ask that what is volumetric flow?

So, volumetric flow is the amount of the fluid flowing or volume of fluid flowing through the media per unit of time. In short, the volume of the flowing fluid per unit time.

Hence, knowing briefly about these two measuring devices above now let’s move on to the comparison section between these two devices, keeping your purpose of landing here.

So, here it is-

Difference between orificemeter and venturimeter-

Here is the side by side comparison of the orificemeter and venturimeter in the table down below-
