Title:
ULLAGE MEASURING DEVICE FOR COMPRESSIBLE FLUID
Document Type and Number:
Japanese Patent JP2566114
Kind Code:
B2
Abstract:
PURPOSE: To provide an ullage measuring device enabling instrumentation of high reliability in a short time without needing manual help in individual instrumentation and measuring operation and without individual elements entering.
CONSTITUTION: An ullage measuring device for a compressible fluid is provided with a liquid container 11, a measuring cylinder 15 inversely supported with the opening end part l5a submerged in the liquid in the liquid cylinder 11, and a connecting tube 23 with one end 23a opened to the opening end part of the measuring cylinder 15 and with the other end 23b communicated with a measured space so as to lead a leaked compressible fluid into the measuring cylinder 15. The upper part closed end 15b of the measuring cylinder 15 is provided with a fluid level detecting ultrasonic sensor 17, and an exhauster is connected adjacently to the closed end 15b. The bottom part of the liquid container 11 is provided with a conical reflecting plate 25 opposed to the ultrasonic sensor 17 through the opening end of the measuring cylinder 15. A measuring control device 30 is electrically connected to the ultrasonic sensor 17.
