Fundamentals of Orifice Metering

Introduction The history of orifice metering began in the early 1900’s. The first test data was done by the U.S. Geological Survey and in 1913 the first “Handbook of Natural Gas” was published. So as you can tell, orifice metering has been around for over 100 years and in that time much has been learned …

FUNDAMENTAL PRINCIPLES OF DIAPHRAGM DISPLACEMENT METERS

INTRODUCTION The first gas company in the U.S., The Gas Light Company of Baltimore, Maryland, founded in 1816, struggled for years with financial and technical problems while operating on a “flat rate” basis. Its growth was slow with the charge for gas service beyond the pocketbook of the majority.

ULTRASONIC METERS FOR RESIDENTIAL AND COMMERCIAL APPLICATIONS

INTRODUCTION An ultrasonic meter falls into the classification of inferential meters. Unlike positive displacement meters that capture volume to totalize volume, inferential meters measure flowing gas velocity to totalize volume. Orifice meters use pressure drop to measure velocity to infer volume and turbine meters use the speed of the rotor to measure velocity to infer …

FIELD TESTING BY TRANSFER PROVING

INTRODUCTION Transfer proving was initially developed to provide an easier and more accurate field meter proving method. Because of the capacity capabilities of transfer provers (2000 CFH to 80,000 CFH) transfer provers are utilized in meter shops where bell prover capacity is limited and allow for shop testing of the larger capacity meters.

PROTECTION OF NATURAL GAS MEASUREMENT EQUIPMENT AGAINST MOISTURE AND CORROSION

INTRODUCTION The natural gas industry relies very heavily on sensitive electronic equipment utilized in the production, gathering, transportation, and distribution phases. There is an increasing reliance on the use of electronics for performing important tasks relating to measurement, control, and safety. Coupled with increased reliance is the demand by users for increased reliability.

FUNDAMENTALS OF PRESSURE RELIEF VALVES IN NATURAL GAS INSTALLATION – OPERATION – MAINTENANCE

What Are They and Why Are They Needed What: A stand-alone device that opens and recloses at a pre-selected pressure, containing an orifice sized to flow a required capacity to prevent / avoid overpressure. Why: All natural gas equipment (pipelines, pressure vessels, air-cooled heat exchangers, compressor cylinders, odorant tanks, instrument control lines, valves, underground storage, …

Field Inspection and Calibration of Volume Correcting Devices

INTRODUCTION Timely, diligent field testing and calibration of gas volume recording and correcting Instruments ensure that measurement Information fairly represents actual volumes. The Instruments save a company capitol and operating costs because they can record or integrate volumes at pressures and temperature above the normal pressure- base conditions specified In contracts for volume calculation. This …
