Title: Method and apparatus for monitoring leakage of liquid enclosed in sealed circulating system
Inventor: KABETA AKIRA
IPC: G01M3/26
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for automatically monitoring the leakage of liquid of public nuisance causing substance such as refrigerant liquid sealed, for example, in a turbo refrigerator. SOLUTION: A luminous flux is emitted from a light emitting unit 2 toward a transparent plate mounted at an inspection window 1e, the reflected flux from the inner surface of the plate is received by a photoreceiver 3, and the electric signal obtained by photoelectrically converting it is inputted to a control circuit 7. When the level of the refrigerant liquid if becomes lower than the reflecting point, the emitted flux is strongly reflected to increase the quantity of the reflected flux. When the level of the liquid 1f is higher than the point, the reflection is weak, and hence the quantity of the reflected flux is remarkably low, and hence the reflected flux is detected to discriminate the level position. When the level becomes a predetermined level or lower, the circuit 7 lights an alarm lamp 8a, or rings an alarm unit 8b.
