Abstract:
A DC pressure and temperature sensor system, for sensing and measuring the DC pressure and temperature of a production fluid in tubing, comprising: a fluid sensor including a sensing material in which sound travels at a rate that depends on the DC pressure and temperature of the sensing material, the sensing material coupled to the production fluid so as to be at a DC pressure and temperature that can be correlated to the DC pressure and temperature of the production fluid, the fluid sensor responsive to the DC pressure and temperature of the production fluid via the coupling of the production fluid to the sensing material, for providing sensing signals containing information about the DC pressure and temperature of the production fluid, thereby enabling a determination of the DC pressure and temperature of the production fluid given one item of further information related to the DC pressure of the production fluid or to the temperature of the production fluid or related to the DC pressure and temperature of the production fluid in combination.
