PURPOSE:To facilitate exchange without the occurrence of a pressure loss and to enable to perform a smooth operation of a blast furnace, by a method wherein signals from transducers mounted to lines for a plural number of tuy ere are selected, in order, to measure a flow rate by a time division. CONSTITUTION:Transducers are mounted to their respective lines for a plural number of tuy ere of a blast furnace. A measuring device body is installed, and selects in order signals from each transducer via a switch to measure a blast discharge to each tuy ere of the blast furnace by a time division. For example, transducer 3 is mounted to an outer surface of each of about 40 lines 2 for the tuy ere of the blast furnace 1 by means of a band. The signal from each transducer 3 is supplied to a single switching circuit 5 through transmission cables 4, and signal, being selected in order, is sent to a measuring device body 6 to measure a discharge in each line 2 by a time division. |
