Abstract
Apparatus for the remote measurement of physical parameters, the apparatus comprises a sensor (1) for sensing one or more physical parameters, an interrogator (2) for interrogating the sensor (1) and making a measurement, a cable (3) for extending between the sensor (1) and the interrogator (2), a conduit (4) for extending to a measurement location (5) and which is of such a cross-sectional size that it is able to accept the cable (3) and the sensor (1), and a cable installer (6) for installing the sensor (1) and the cable (3) through the conduit (4) and for placing the sensor (1) at the measurement location (5), the cable installer (6) being such that it includes a device (7) for propelling a fluid along the conduit (4), and the conduit (4) being such that it contains a lead-in section (8) for providing sufficient fluid drag on the cable (3) as it enters the conduit (4) from the cable installer (6) to ensure that the sensor (1) is able to be transported through the conduit (4).
