ンプ吸込揚程を加算したポンプ全揚程と、ポンプ
回転数を知りポンプＱ−Ｈ特性より正常であるべ
き流量と流量発信器からの流量を比べて流量発信
器の異常の有無を判別することを特徴とする流量
発信器の異常の有無の判別回路。 In the pump water supply system, determine the total head of the pump, which is the sum of the pump discharge head and the pump suction head, and the flow rate of the flow transmitter by knowing the pump rotation speed and comparing the flow rate that should be normal based on the pump Q-H characteristics with the flow rate from the flow transmitter. A circuit for determining the presence or absence of an abnormality in a flow rate transmitter, characterized by determining the presence or absence of an abnormality.
