An Update Of New Measurement Equibffiwt And Procedures
Author(s): Henry C. Judd
Abstract/Introduction:
Since our last meeting there have been a nrniber of new developments in the field of measurement in both my Company and throughout the industry. It is the purpose of this report to update you on as many of these as time permits. Two of the developments that have made our jobs more challenging in recent years are: 1) an ever increasing number of new techniques for measuring gas flow, and 2) a radical change in load swis by some of our larger customers.

Testing Facilities At Rocrarenxs Dubois Iaboratory
Author(s): William L. Murphy
Abstract/Introduction:
The measurement of gas is accomplished by the use of meters with capacities ranging from about 100 CFH to well over 100,000 CFH. The advent of natural gas broht high pressure pipelines into virtually every community of any size in this country. This, in turn, was accompanied by various developments in large volume measurement. Large rotary meters and turbine meters were among these developments.

American Gas Turbine & Cvm Meters
Author(s): Wilbur W. Lints Mike Neeley
Abstract/Introduction:
Introduction iiience has proven that all gas measuring devices require periodic testing and perhaps preventive maintenance to insure extended meter life and sustained accuracy. Depending on the type of meter, maintenance may be in the form of lubrication, cleaning, inspection of moving parts, and parts replacement. The frequency of testing and maintenance of meters will vary, depending on Company policy, purity of the gas and gas system and Public Utility Commission regulations. It is advantageous to use meters which, by design, will minimize testing and maintenance procedures,thereby decreasing down time

Operation And Calibration Of The Daniel Flow Computer And Transducer
Author(s): J. W. Townsend
Abstract/Introduction:
TEST EQUIPMENT AND SPECIAL TOOLS - The following list contains the normal metering tools which are required for system calibration. Built-in test circuitry provides a means for trouble shooting the multi-range computer without external electrical equipment. The Model 1271 does not have built-in test circuitry except for time check. This model, in case of trouble, can be checked with standard electronic trouble-shooting equipment.

Installation, Operation, Start-Up And Maintenance For Flow Computing Systems
Author(s): Richard H. Cadmus
Abstract/Introduction:
This paper will cover the reconnnendations and some comments regarding installation, start-up and maintenance of flow computing systems from the standpoint of the manufacturer. Certainly we manufacturers would like to see all equipment installed in controlled environments and maintained by highly qquuaal ified electrical engineers. However, we also realize that t extremely impractical is designed to exist and perfort rkiabthis is certainly and the equipment ly and reasonably under more realistic conditions. I will attempt to cover some points which, in my experienc,. have some bearing on successful operation of the flow computing system.

Trends In Measuremeot
Author(s): Ken Kridner
Abstract/Introduction:
Some years have passed beyond the horizon since I had the privilege of working with you and others of the measurement fold at a company whose headquarters rest on the base of Pikes Peak. In those days, automation was a dirty word, something to be scorned by those with a number of years under their operating belt and who not only did not understand the mysteries of the little black boxes, but really cared little to know more. This was the unfortunate situation that surrounded the early days of remote control and automation. A

Abstract/Introduction:
This class will deal with some of the pneumatic and electronic field testing equipment we now have available to the gas industry. Time will not permit us to cover all the equipment, so we shall discuss the most used and also some new electronic equipment. will start with the Manometer. I have heard it said that the manometer is to gas measurement what the human heart is to the body. Flow control, pressure regulatinn and displacement metering owe their dependability to manometer references

Transfer Proving
Author(s): Kenneth m. Bordner
Abstract/Introduction:
Transfer proving is becoming a nationwide practice for several very obvious reasons. The reasons are as follows: 1. Elimination of the necessity of meter removal for testing. This allows a longer field life. 2. Field proving allows more consistent meter proving through greater repeatability. a. Errors can be eliminated because the time required to make a proof is minimized. b. The timing is automatic, which eliminates stop watch errors. c. Pressure reading is automatically corrected.

Rocrweii Reguiators Am) Associated Theory
Author(s): John Iaughner
Abstract/Introduction:
Too often a class on the repair and maintenance of regulators is confined rictly to the physical work that can be performed on the regulator. Quite frankly, I feel that there is more to this area than just the actual work. Many times when we find a regulator working improperly we naturally assume that it has been properly selected and installed. However, the initial information that any gas engineer must work with is only so reliable and situations can change such as load requirements, pressure and required performance. These changes can cause any regulator to perform unsatisfactorily.

The Flexflo Reguiator
Author(s): Milton H. Craven
Abstract/Introduction:
The Grove Flexflo is a valve of unique design. The operating member is an expansible tube. This tube is slipped over a cylindrical metal core having a series of longitudinal slots at each end, with a separating barrier between. Action of the expansible tube is determined by control of the differential pressure across it. In its operation the Flexflo valve resembles a diaphragm motor valve with the expansible tube acting as both diaphragi and inner valve. The tube is made S-om a Grove formulated synthetic elastomer especially compounded to assure a high degree of tear and abrasion resistance, flexibility and strength

Abstract/Introduction:
When does a gas utility decide to make a change in the type of residential and comtnercial regulators they are using? A number of factors introduced in the last few years have made gas utilities more concerned with proper regulation of gas. With rapid eansionof industrial, commerical and residential use of natural gas, coupled with the newer and more complex utilization equipment, many utilities have had to revise thkr thinking in regards to applicatioss and regulator types and capabilitie,, which are causing much concern in the Department of Transportation Rules and Regulations of Natural

Meter Station Noise Forecasting
Author(s): Doug Schacker
Abstract/Introduction:
Noise in the meter station is produced by noise generators within the piping system. These noise generators can be swages, headers, compressors, gate valves, heaters, regulators, control valves or any other device capable of transforming potential and kinetic energy into sound energy. Technical advances have made it possible to measure this sound accurately. What is more important, however, is that empirical testing and data gathering has produced a technique for forecasting a majority of the noises generated at a meter station.
