Flow & Level Calibration Notes

Differential Pressure Transmitter Calibration

Introduction

In the Differential Pressure Transmitter, as flow increases, the differential pressure increases, and when flow decreases the differential pressure decreases. For example, an orifice plate is placed in a pipe to restrict the fluid flow. This restriction creates a pressure drop that can be converted to flow rate. The differential pressure transmitter measures the pressure drop created, by...

Static Properties, not in motion

Static pressure, the pressure exerted by fluids at rest.

Density

Density is a measurement of the proximity of molecules that make up a substance. Density is Mass per Unit of Volume ( r = m / V ), where: r = Density, m = Mass, and V = Volume.

Effects of Temperature and Pressure on Density

Heating causes a substance to expand, increasing its volume, and decreasing its density. Cooling causes a substance to contract...

Multiphase Metering - The Challenge of Implementation

Mr A.W. Jamieson, Shell U.K. Exploration and Production

1. Introduction

“Multiphase flow measurement” is a term that has been increasingly heard since about 1980 amongst operators in oil companies and designers of oilfield facilities. For some, it promised measurement capabilities under new and trying conditions. They saw a need to simplify the design and improve the control of production...

Orifice Plates

Orifice Plate - An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate). Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate. It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of...

Recent Experience on Implementation of New Techniques of Gas Metering

Andrew W. Jamieson, Shell U.K. Exploration and Production

1. Summary

Gas metering in the oil and gas industry is changing rapidly with the steady introduction of new metering techniques, which will supplant or co-exist alongside traditional methods. Gas metering fits readily into a concept in which any oil and gas industry metering application is a special application of multiphase metering. Recent experience in...
