Self sufficient electronic system for monitoring and continuous surveillance of steam traps, valves and installations using fluids. The system comprises three essential elements: a multi sensor, an electronic analyzer and an optional receiver. The sensor measures fluid conductivity, pressure and temperature. The electronic analyzer continuously controls the status (pressure, temperature) and conductivity of fluid, supplying optical, acoustic and digital information, in situ or from a remote point, in accordance with the results of analysis carried out. The receiver centralizes and processes the signals emitted by the analyzer. The analyzer electronic circuits are fed by batteries recharged through photovoltaic cells incorporated in the equipment. The multiple probe also incorporates an ultrasonic sensor which detects ultrasounds generated in the steam trap or valve. The analyzer and the remote receiver also add the corresponding electronic circuits for a continuous surveillance of ultrasounds level. This system may be applied to the continuous surveillance and control of steam leaks and, generally, to control fluid flow in any installation. The system can solve the problem of automatic inspection and continuous monitoring of energy losses in steam traps, without human attention. It substantially reduces power consumption by detecting steam losses simultaneously and instantly at all points of installation.
