Abstract

PURPOSE:To save electric power consumption, in a plugging meter which measures the impurity concentration in a coolant in an atomic reactor, by controlling the power used for a cooling blower with respect to the change in temperature of a sampling fluid by using a function generator and a change rate restrictor. CONSTITUTION:The temperature of a sampling fluid is detected by a temperature detector 12B and inputted to a function generator 17. The output signal of the function generator operates a power controller 14B through a change rate restrictor 18 and controls power Pc for a cooling blower. The output A of the function generator 17 is changed from A3 to A2 when the temperature of the sampling fluid becomes T2-DELTAT/2. Then the signal change is restricted by the change rate restrictor 18, and the power for the cooling blower is changed.
