A Gas Leak Detector and a Method of Detecting a Leak of Gas
A gas leak detector for detecting gas leakage from a flow path between a first flow restriction and a second flow restriction to gas flowing in the flow path, the first flow restriction upstream and spaced apart from the second flow restriction, the gas leak detector comprising: a first sensor devic...

| description | A gas leak detector for detecting gas leakage from a flow path between a first flow restriction and a second flow restriction to gas flowing in the flow path, the first flow restriction upstream and spaced apart from the second flow restriction, the gas leak detector comprising: a first sensor device for sensing a first difference between a first pressure of gas upstream of the first flow restriction and a second pressure of gas inside or downstream of the first flow restriction in the flow path and to generate on the basis of the first difference a first electrical signal indicative of a first mass flow rate of gas through the first flow restriction; a second sensor device for sensing a second difference between a third pressure of gas upstream of the second flow restriction and a fourth pressure of gas inside or downstream of the second flow restriction in the flow path to generate on the basis of the second difference a second electrical signal indicative of a second mass flow rate through the second flow restriction; and a comparator for comparing a first magnitude of the first electrical signal and a second magnitude of the second electrical signal and generating an alarm signal if a difference between the first magnitude and the second magnitude is greater than a threshold value and/or generating a safe signal if the difference between the first magnitude and the second magnitude is lower than the threshold value. |
