ABSTRACT:
A gas leak detection system comprises a flow sensor for detecting the amount of gas flowing through a gas flow passage, a flow signal generator for producing a flow signal representing the quantity of gas flow detected by the flow sensor, a pressure sensor installed in the gas flow passage at a point upstream of the flow sensor for detecting the gas pressure in the gas flow passage, a pressure signal generator for producing a pressure signal representing fluctuations in the pressure detected by the pressure sensor and a computing device electrically connected with the flow signal generator and the pressure signal generator. When it is found that no flow signal is being produced, the pressure fluctuation is compared with a prescribed pressure fluctuation range and a leak signal is produced when the pressure fluctuation value falls within the prescribed range.
