Abstract
A pressure indicator according to the present invention monitors the pressure of the fluid in a vessel. One embodiment of the present invention comprises a closed pressurized gas volume behind a dimpled metal diaphragm. In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm overcomes the force of the gas pressure acting on the internal surface of the diaphragm to hold the diaphragm in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of the diaphragm will overcome the force of the fluid pressure acting on the external surface of the diaphragm, thereby moving the diaphragm into a convex geometry. A viewing window disposed in the side of the vessel can be used to view the pressure indicator and determine the shape of the indicator diaphragm.
