SYSTEM FOR DETECTING LEAKAGE OF FLUID MEDIA AND ALARM SIGNAL Russian patent published in 2009 - IPC G01M3/16 G08B25/00 

FIELD: physics; measurement.

SUBSTANCE: present invention relates to means of monitoring air-tightness of, for example pipes or reservoirs. A leak detecting device is placed on the place of possible leakage, at a distance from a receiving-actuating device, the input of which is connected to the output of the leak detecting device through a communication channel. The leak detecting device contains a leak sensor, data transfer unit and a processor, the first data input of which is connected to the output of the leak sensor, and the output to the data input of the data transfer unit. The output of the data transfer unit is the output of the leak detecting device. There is a first power supply, the output of which is connected to power inputs of the processor and the data transfer unit. The receiving-actuating device comprises a controller, display and alarm actuating unit, a second power supply and a receiver. The input of the receiver is the input of the receiving-actuating device, and the output is connected to the data input of the controller. The output of the controller is connected to the data input of the display and alarm actuating unit. There is a second power supply, the input of which is connected to the output of the above mentioned actuating unit, and the output to power inputs of the receiver, controller and actuating unit. The leak detecting device also contains an inertial positioning unit, which can detect unauthorised displacement and unauthorised rotation of the leak detecting device around any of its axes. The power input of the above mentioned inertial unit is connected to the output of the first power supply. The processor has a second data input, which is connected to the output of the inertial unit.

EFFECT: design of a system which is convenient and reliable to use in household conditions.
