1.Introduction
Floating ball type pressure gauge is an aerodynamic loading-type pressure gauge, which using compressed air or nitrogen as the pressure source, and using the pressure applied areas of the under parts of the precision floating ball in working state as its effective area. The precision floating ball is built in a cylindrical nozzle, and specific weights are applied to the top of the floating ball by the support frame, the pressure of the nozzle is acted on the under parts of the floating ball to make it floating in the nozzle. The pressure gauge will output a stable and accurate pressure value when the gravity caused by specific weights(quality is known) and force applied by the gas pressure are in equilibrium. 2.Technical Parameters
