PURPOSE: To obtain an automatic high temperature high pressure water supplying equipment which can keep a constant sample water supply amount correctly and efficiently through a relatively simple structure. CONSTITUTION: In the automatic sample water supplying equipment, a high temperature high pressure sample water from a boiler plant 10 is cooled, at first, by a cooler 12 and then the pressure thereof is reduced to the normal pressure through a pressure reducing mechanism 14 and a constant head vessel mechanism 20 with flow-in and flow-out lines 16, 18 before the sample water is fed through a piping system 22 to a measuring instrument 24. The head vessel mechanism 14 is provided with a flow rate detector 40 on the flow-in line 16 thereof and the pressure reducing mechanism 14 controls the secondary pressure thereof (pressure on the upstream side of the flow-in line 16) through the flow rate detector 40, a flow rate setter 42 and a controller 44. Consequently, the vessel flow-in rate (i.e., the flow-out rate)ΔQ is held at a constant level thus keeping the sampling quantity Q from the boiler plant 10 and the supply quantity (q) to the measuring instrument 24 at a constant level.
