<p>There is disclosed a device and method to measure the back pressure in chemical reactor tubes. In a preferred embodiment the device comprises a wand (18) which uses an inflatable, conforming seal in the form of an elastic sleeve (56) mounted on an injector tube (30). Thereby a good seal is provided between the measuring device and the chemical reactor tubes. Also, in a preferred embodiment, the measuring device measures multiple tubes at once rather than measuring only one tube at a time. Also, in a preferred embodiment, measurements are stored at the measuring device, are transmitted electronically to a remote computer, and are displayed graphically in real time at a remote display, such as in the control room, including indications of which tubes are within predetermined specifications and which are not.</p> |
