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.
Step 4. REMOVE PRESSURE GAUGE-The Pressure Gauge is located on the end of the Air Relief Valve on the Hayward DE Filter. Twist the Gauge off in a counter-clockwise direction. If it does not turn easily, use an open end wrench on the brass nut at the base of the Gauge.tep 3. RELIEVE PRESSURE-Next you will have to relieve the pressure that builds up in the filter during operation. To relieve pressure turn the Air Relief Valve lever on top of the filter counter-clockwise. Water may spray out initially as you see the pressure on the Pressure Gauge go to 0 psi.
