Claim:
1. A pressure testing device for calculating a pressure in a flexible line, the device comprising: a housing unit; a force sensor mounted on the housing unit; a clamp assembly having a clamp mounted on the housing unit, the clamp being operable to compress the flexible line against the force sensor by a predetermined degree of deformation of the flexible line; a displacement sensor adapted to measure a change in an outer diameter of the flexible line after the outer diameter of the flexible line has been compressed by the clamp to the predetermined degree of deformation; a controller having: wherein at the predetermined degree of deformation of the flexible line, the processor compares a force signal from the force sensor and a displacement signal from the displacement sensor with the stored data to determine the pressure within the flexible line; and an output device, coupled to the controller, wherein the controller is adapted to send an output signal to the output device, and wherein the output device is configured to provide a first output corresponding to a first pressure, a second output corresponding to a second pressure, and a third output corresponding to an error, indicating that retesting is required, based on the output signal, wherein the first output indicates that it is safe to decouple the flexible line, wherein the second output indicates that it is unsafe to decouple the flexible line, and wherein the flexible line is decoupled based on the first output.
