Instead an organization named the Association for Intercollegiate Athletics for Women (AIAW) governed women's collegiate sports in the United States. By 1982, however, all divisions of the NCAA offered national championship events for women's athletics and most members of the AIAW joined the NCAA.
Mechanical pressure gauges are connected directly to the process fluid being measured (i.e. oil). As the process fluid pressure changes the pressure on the bourdon tube also changes which in turn moves the pointer on the gauge. Mechanical temperature gauges also utilize a bourdon tube. They have a sealed capillary tube and bulb assembly that is filled with temperature sensitive liquid that produces a proportional vapor pressure on the bourdon tube.
Both of these pressures are the result of the regulators on the gas line. In the case of natural gas, the meter acts as a measure of volume (so you can get a bill) and as a regulator. In many situations, you'll have 25-35 PSI of natural gas coming into the meter. The meter reduces this pressure to 5-8 wc.
