Abstract
Methods and apparatus for the remote measurement of physical parameters are described. The apparatus includes a sensor, sensor instrumentation, a carbon coated optical fiber cable for extending between the sensor and the sensor instrumentation, a conduit for extending to a measurement location and configured to accommodate the optical fiber cable and the sensor, and a cable installing device configured to install the sensor and the optical fiber cable through the conduit and place the sensor at the measurement location. The cable installation device includes an apparatus for propelling a fluid along the conduit, such as a pump, a compressor, and the like. In the method, a sensor is installed at a measurement location by pumping the sensor and a carbon-coated optical fiber cable through a conduit, forming a seal around the cable where it enters the conduit, and connecting the cable to sensor instrumentation.
