A method for remotely measuring pressure of a fluid in a container includes determining a spatial location of first and second resonant radiofrequency antenna elements located on a radiofrequency identification (RFID) tag located in the container. The first antenna element is positioned in a fixed position on the RFID tag and the second antenna element is positioned on a deformable element configured to be deformed in at least one dimension based on pressure from the fluid. The spatial location is determined from a radar image generated based on reflected radiofrequency beams from a scan area and re-radiated radiofrequency beams from the first and second antenna elements located within the scan area. A pressure value is determined for the fluid based on the spatial location of the first and second antenna elements. Systems and methods of remotely measuring pressure using passive RFID tags are also disclosed.

Tire mounted sensors have controlled orientation with respect to a direction of vehicle travel when fitted to a tire of the vehicle. The tire mounted sensor includes a sensor housing containing a pressure and/or other type of sensor and electronic components which is inserted into a sensor mount attached to the tire. Controlling the orientation of the orientation-sensitive components relative to the direction of travel of the vehicle is achieved by indicating the direction of travel of the vehicle on the sensor mount. Controlling the orientation of the sensor housing within the sensor mount, preferably in all six axes of freedom, is achieved by an orientation key or asymmetrical feature on the sensor mount that corresponds to a mating feature on the sensor housing.
