发明名称 AN ARRANGEMENT FOR THE MEASUREMENT OF THE DIFFERENCE BETWEEN TWO FLOWS IN TWO SEPARATE DUCTS
摘要 An arrangement for the measurement of the difference between two flows in two separate ducts with the help of one or more monitoring electrodes or the like arranged in respective ducts. The flow in the one duct is adapted so that it is capable of being transferred to the other duct. This can be done, for example, with the help of means for the alternate change-over of the flows from the respective ducts to the opposite duct, so that ultimately all the electrodes and/or duct walls are acted upon to a substantially equal extent. <??>Alternatively this may be achieved with the help of means for conducting one and the same flow through both ducts when the flow difference becomes zero and the measured value can be used as a new zero value for the continued measurement.
