Abstract

An apparatus (10) for detecting the transmission of catalyst plugs through a conduit (105) leading to a, polymerisation reactor, comprising an optical radiation source (9) located outside the conduit which passes a light beam (9a) through the conduit along a light path and an optical radiation detector arranged to detect the light beam. When a catalyst plug passes through the conduit it blocks the light path and thus the light intensity recorded by the detector drops. In this way catalyst plugs can be detected. The apparatus can also be used to measure the mass of an object passing through a conduit by repeatedly detecting the speed of the material and the light intensity, multiplying the speed and intensity values to get a result curve and integrating this curve in order to obtain a value indicative of the mass of the material.
