<P>PROBLEM TO BE SOLVED: To prevent a useless processing or operation from being performed by recognizing a state that a secondary pressure is rising due to not the failure of a pressure regulator but other factors. Ž<P>SOLUTION: The secondary pressure monitoring device 17, which monitors a secondary pressure in a pressure regulation facility in which a pressure regulator 2 for freely adjusting the secondary pressure of a fluid feeding path 1 to a set pressure is installed in the middle of the fluid feeding path 1, includes a pressure rising state determination means 19 for determining whether or not it is a normal pressure rising state that the secondary pressure rises due to one or both of the change of the atmosphere of the fluid feeding path 1 and the change of the temperature of the fluid of the fluid feeding path 1 when the secondary pressure rises.
