Abstract
A system and method for testing a fluid seal in a device can include pumping fluid to the device and a control device simultaneously, while measuring the pressure of the fluid pumping to both devices. A change in volume of the fluid in the control device can be initiated, a change in pressure difference associated with the change in volume can be determined, and a leak test ratio can be formed therefrom. Changes in the pressure difference can be used to determine the presence of fluid leaks, which can be presented as test results to users connected to a network. A leak volume can be determined using the change in pressure difference and the leak test ratio.
