Abstract
A conduit pressure sensor system and a process for non-intrusively determining the pressure within a conduit. In one example, the sensor system has a base section having an external surface and an internal region in fluid connection with the conduit. A strain sensor and a temperature sensor are positioned adjacent to the external surface of the base section.
Claims14
A method for non-intrusively determining a pressure within a conduit comprising:
- providing a base section having an internal region in fluid connection with the conduit, wherein the base section is made of a non-corrosive alloy;
- providing a strain sensor and a temperature sensor which are positioned adjacent to an external surface of the base section;
- measuring a temperature with the temperature sensor;
- measuring a strain with the strain sensor, said strain is based on an internal pressure of the conduit and the temperature of the conduit, wherein at least one of the strain sensor and temperature sensor are comprised of fiber optics;
- and
- calculating a pressure within the conduit based upon the measured temperature and the measured strain.
