Abstract:
1. A method for measuring back pressure in open ended chemical reactor tubes, the method comprising: a. connecting a plurality of test heads to individually removable and replaceable test head umbilicals; b. connecting the individually removable and replaceable test head umbilicals to a multiport manifold; c. connecting the multiport manifold to a continuous real-time monitor and display device; d. connecting the continuous real-time monitor and display device to a controller; e. providing power to the controller and transmitting power through the controller to the continuous real-time monitor and display device, the individually removable and replaceable test head umbilicals, and the test heads; f. allowing compressed air to flow from a compressed air source through the controller to the continuous real-time monitor and display device, then to the multiport manifold, then to the individually removable and replaceable test head umbilicals, and to the test heads; g. inserting customer preset pressure limits into a controller data storage connected to a controller processor of the controller; h. pre-testing the test heads against a known loaded chemical reactor tube with a known pressure to ensure proper calibration within +/−1 percent; i. inserting the pre-tested test heads into a loaded chemical reactor tube; j. individually initiating pressurization of each test head in the chemical reactor tubes by activating the continuous real-time monitor and display device; k. transmitting sensor signals to the controller from a test head transmitter/sensor on the test heads to provide the controller with sensed pressures on a real-time basis; l. using the controller to compare the sensor signals to the customer preset pressure limits, forming compared sensor results; m. transmitting the compared sensor results to the continuous real-time monitor and display device; n. presenting the compared sensor results to a local user on a display of the continuous real-time monitor and display device; and o. transmitting the compared sensor results over a network to a remote user, or combinations thereof.
