Apparatus for the remote measurement of physical parameters

An apparatus for the remote measurement of physical parameters, comprising:

• a sensor, sensor instrumentation, an optical fiber cable comprising a carbon coated optical fiber 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 cable installation means oonfigured to install the sensor and the optical fiber cable through the conduit and place the sensor at the measurement location, the cable installation means including means for propelling a fluid along the conduit, the conduit being such that it contains alead-in section providing sufficient fluid drag on the optical fiber cable as it enters the conduit from the cable installation means to ensure that sensor is able to be transported through the conduit, and wherein the cable installation means includes an orifice through which the optical fiber cable is able to be progressively pulled while deploying the sensor, and wherein the orifice is such that sufficient fluid flows through the conduit in order to transport the sensor.
