20120247189 | METHOD OF MEASURING THE SIZE OF A LEAK IN A PNEUMATIC AIR CIRCUIT AND A RELATED DEVICE - A leak detecting device comprising: a housing with gas inlet, a gas outlet, at least one pressure gauge for measuring the gas pressure supplied to the tested system, at least one flow meter for measuring the flow of the gas from the device to the tested system, at least one flow control valve to vary the gas flow through the device, an operating valve for permitting the flow of the gas from the device into the system to be tested. When said device is utilized, the inlet is attached to a pressure generating apparatus, the outlet is attached to the system to be tested, said pressure gauge showing the system testing pressure, and the flow meter indicates the flow of the gas through the device and the system being tested, thereby indicating the existence of any leakage and quantifying the total size of the leakage. | 10-04-2012 |
