Abstract

PURPOSE:To reduce an error of an indication value of a recorder water gauge, by detecting a fluid pressure loss contained in a measuring pressure and a correction value against an indication value of a differential pressure gauge. CONSTITUTION:One side of a differential pressure gauge 12 is connected to a steam drum 1 through a line 8 for measuring pressure of an air phase part, a reference plane device 10, and a reference line 11. A bypass line 16 installed to a fall line ranging from the steam drum 1 to a mixing ball 3, and an orifice 18, working as a fluid resistance, is connected in series in the bypass. A measuring line 9, joined to one side of the differential pressure gauge 12, is connected to the steam drum (1) side at the upstream of the orifice 18. The fluid resistance of the orifice 18 is set lower than that of a fall pipe 2, and this permits the reduction in a fluid pressure loss in the line of the fall pipe 2.
