The difference between valves acc. to ISO 15848 & bellow-sealed valves

The difference between valves acc. to ISO 15848 & bellows-sealed valves.

Diminishing natural resources and expanding energy use are forcing the industry to regroup. The growing stringency of legal requirements obliges companies to use emission-reducing equipment.

Useful little helpers in the measurement of natural gas

DirectMountSystem - How to eliminate gauge line errors in natural gas applications.

Field research and testing conducted by Southwest Research in San Antonio, Texas and the Pipeline Gas Compressor Research Council (PCRC) confirmed that pulsation created by compressors, flow control valves, regulators and some piping configurations may create undesirable levels of Square Root Error (SRE) and/or resulting Gauge Line Error (GLE). Pulsation at the orifice meter is a major source of lost and unaccounted for natural gas. These errors create either large economic gains or losses for the buyer and seller along a natural gas pipeline system.
