PURPOSE:To accurately measure the presence of ebullition and the quantity of steam at the time of ebullition, by performing the confirmation of the ebullition point of high temp. and high pressure water and the measurement of the quality of steam from the measurement of the signal intensity between a pair of monitor windows. CONSTITUTION:The transmitting sensor 15 connected to a transmitter 14 for sending an optical signal is arranged on the lateral side of one of the monitor windows 13 of a test tank vessel 1, and the receiver 16 receiving the optical signal and a receiving sensor 17 are arranged on the lateral side of the other monitor window 13. The transmitting and receiving data of both sensors and data of temp., pressure or the like are sent to a computer 19 through an interface 18. The quantity of the steam in the two-phase stream of high temp. and high pressure steam can be continuously calculated by the computer 19.
