PURPOSE:To measure the liquid surface accurately and simply, by excluding the unnecessary signal part of measured value subject to the mixer through the use of calculator, in the method measuring the liquid surface of reaction tank having a mixer. CONSTITUTION:The measurement value A of position change only for the mixing wing 2 of a mixer measured continuously in advance at the liquid surface detectors 7 and 8 is stored in the calculator 9. Next, the value of liquid surface measurement value B in the tank 1 and the position signal C of rotating circumferential direction of the mixer 2 are stored in the calculator 9 at actual running, the position signal C is used for synchronizing the both measuring values A and B as the synchronous pulse and the liquid surface is measured with the subtraction of the measuring value A from the value B. |
