All About Provers: What Is It and What Are The Types

A prover is a device designed to calibrate or prove a liquid flow meter's accuracy and repeatability under actual operating conditions. There are different types of provers available in the market that includes pipe provers, unidirectional provers, and bi-directional provers. Each prover is equipped with cutting-edge sensors that can detect any deviation in fluid or gas flow.

  1. All About Provers: What Is It And What Are The Types --- ⋆⋆⋅☆⋅⋆⋆---⋆⋆⋅☆⋅⋆⋆---⋆⋆⋅☆⋅⋆⋆---⋆⋆⋅☆⋅⋆⋆---⋆⋆⋅☆⋅⋆⋆---⋆⋆⋅☆⋅⋆⋆---⋆⋆⋅☆⋅⋆⋆---⋆⋆⋅☆⋅⋆⋆---⋆⋆⋅☆⋅⋆⋆--- You may have heard about provers and several types of it majorly used in Oil and Gas industries. However, you may not know what is it and what the types are. In this blog, we will go through what a prover is and some of its types. Let’s begin by understanding a prover. What is a prover? A prover is simply a device designed to prove a fluid flow meter’s accuracy and repeatability under certain operating situations. They can either be stationary or portable devices that are used to calibrate and verify the accuracy of both - volumetric and mass flow meters.

  2. Pipe provers A pipe prover, also known as a sphere prover or a ball prover is a device that constantly replicates displacements of liquid. This helps industries compare volumes and whether certain measures need to be taken to modify the variations or not. The working of this prover is such that as the fluid moves inside the ball prover, there is an attached meter that makes the calculations. Unidirectional provers This is just another variation of a ball prover. As the name suggests, the meter prover in place has a unidirectional flow i.e., the displacement ball moves in one direction only. There is a sphere that moves through all the designated points and the sensors attached after which the displaced fluid is compared with the pre-set values.

This prover can also be referred to as a modified sphere prover that allows consistent travel of the displacement ball. The reversal of fluid flow takes place when the sphere changes its direction. The functioning of this prover is simple. The liquid or gas enters the system and pushes the ball in two directions after which it goes through the proving loop. Conclusion Hopefully, the blog helped you understand a prover and its types. If you still have doubts or questions about it, you can contact OGSI. They offer various products, and services for the Oil & Gas Sector of the Middle East and Africa and render after-sales support as well.
