Pressure detection device

A method of calculating a pressure in a flexible line, the method including the steps of:

• calculating an outer diameter of the flexible line with a displacement sensor;
• compressing the line with a clamp against a force sensor by a predetermined degree of deformation of the flexible line;
• sending a force signal from the force sensor to a controller based on a measured force acting on an outer wall of the flexible line, wherein the controller comprises:
• i) a processor in communication with the force sensor and the displacement sensor, and ii) a non-transitory memory containing stored data;
• sending a displacement signal from the displacement sensor to the controller based on a measured 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;
• comparing, by the controller, the force signal and the displacement signal with the stored data to determine an internal pressure within the flexible line;
• sending, by the controller, an output signal to a display device based on the determined internal pressure;
• outputting, by the display device, an indication of the determined internal pressure;
• and
• decoupling the flexible line based on the indication of the determined internal pressure.
