Abstract:

In natural gas distribution systems measurement is highly important for the purpose of both purchase&sale. Also the management of existing natural gas distribution network in the city and providing continuous gas supply is impoartant too. Especially, “local area regulation stations” which are responsible of natural gas company in distribution network should be watched and controlled for the management of the natural gas distribution network properly. In this study, the orifice meter was designed for the purpose of control and measurement in “local area regulation stations” with national and domestic fund. Then, the measurement results of designed orifice meter were compared with the measurement results of existing ultrasonic meter. During the study, the results obtained at different time intervals and different flow rates were evaluated. Experimental study was carried out under real operating conditions of the zone regulator feeding a certain zone. Measurements were made in the months of January, February, March, which are the heating season, as well as in October, November and December.As a result of the study, approximately 98% accuracy was measured with the designed orifice meter.
