An ultrasonic flowmeter for gases by Donald A. Bender, Leon R. Glicksman, Carl R. Peterson.
([Cambridge, Mass.] : Massachusetts Institute of Technology, Energy Laboratory, 1984, 1984)
An ultrasonic flowmeter is developed for use in natural gas mains. The characteristics of the application and the dynamic head device presently employed are described. The performance requirements, design, and prototype ...
The development of a curb valve flow meter for gas theft detection
([Cambridge, Mass.] : Massachusetts Institute of Technology, Energy Laboratory, 1984, 1984)
As the supply of natural gas continues to dwindle, and government decontrol of pricing progresses, the rising cost of this essential natural resource will drive more individuals to consider various forms of pilferage as a ...
An evaluation of joint repair methods for cast iron natural gas distribution mains and the preliminary development of an alternative joint seal
([Cambridge, Mass.] : Energy Laboratory, Massachusetts Institute of Technology, 1984, 1984)
Approximately 10 percent of the natural gas pumped into distribution systems is unaccounted for. A significant portion of this amount is leakage from joints in 50 to 100 year old cast iron main. Because of the cumulative ...
Ultrasonic flowmetering with reflected pulses
([Cambridge, Mass.] : Energy Laboratory, Massachusetts Institute of Technology, 1984, 1984)
A transit time type ultrasonic flowmeter was tested with two different reflected pulse trajectories in flowing air at ambient conditions against an orifice meter. The flowmeter was designed to be highly accurate, to require ...
An internal seal for repairing natural gas mains
([Cambridge, Mass.] : Massachusetts Institute of Technology, Energy Laboratory, 1984, 1984)
Joint leakage from low pressure natural gas distribution mains (typical value: 0.25 ft[superscript 3] at 6 inwg gas pressure) is a persistent source of maintenance problems for utitlites. External encapsulation is the usual ...
