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.

Abstract: Apparatus for the installation of sensors (37) in channels (31), which apparatus comprises a first channel (31) containing at least one sensor location arrangement (35), the first channel (31) and the sensor location arrangement (35) being such that at least one sensor (37) is able to be pumped through the first channel (31) to the sensor location arrangement (35), the sensor location arrangement (35) being provided with at least one turn (3) such that the physical disposition of the sensor (37) after it has been pumped to the sensor location arrangement (35) is not linear, and the turn (3) being such that it comprises a loop of hydraulic conduit.
