摘要： Methods and apparatus are provided for detection of leaks in boilers (12) containing a temperature control liquid which is supplemented with feedwater (36) and removed as blowdown (26), main steam and sootblower steam. In a preferred embodiment, the boiler has an automatic liquid level control mechanism. The methods include measuring rates associated with feedwater supplementation and removal, determining the relationship between water input rate and water output rate; determining the change of mass of the temperature control liquid, determining the unaccounted for water rate, and comparing (28) the unaccounted for water rate with zero to determine if a leak condition is present.

摘要： A fluid leak detection system (210) is provided, and includes a fluid conduit (220), a fluid-cooled device (230) having an inlet and an outlet, an inlet flow meter (224), an outlet flow meter (234), and a controller (250). The inlet flow meter and inlet flow meters (224,234) are fluidly connected to the fluid conduit. The inlet flow meter (224) monitors the inlet of the fluid-cooled device for an inlet temperature and an inlet flow rate. The inlet and outlet flow meters (224,234) each have flow meter drift versus process fluid temperature curves as well as drift versus ambient temperature curves, wherein the curves for the inlet flow meter (224) differ from the outlet flow meter (234). The outlet flow meter (234) monitors the outlet of the fluid-cooled device for an outlet temperature and an outlet flow rate. The controller (250) is in communication with the inlet flow meter (224) and the outlet flow meter (234).

摘要： A method for detecting a leak in a closed-volume liquid system (10) comprises circulating a fluid through a closed-loop with a pump (22) having a reservoir (24) and that is driven by an electric motor (23). The method also comprises sensing a pressure in the closed-loop, sensing current draw by the motor (23) and sensing fluid level in the reservoir (24). The method further comprises determining a presence of a leak of fluid from the closed-loop based upon two of the sensed signals using a first leak detection logic (150), and determining the presence of a leak of fluid from the closed-loop based upon at least one of the sensed signals using a second leak detection logic (150).

摘要： The invention relates to a method for testing the tightness of refrigerating machines, particularly air conditioners in motor vehicles, according to which the apparatus that is to be tested is impinged upon by a gas at excess pressure. The aim of the invention is to create a method which detects all leaks, the size of which has an impact on the environment and health, while requiring substantially less effort to be implemented. Said aim is achieved by separating the adapters (7; 8) of a filling and measuring device from the air conditioner following the first test, connecting the adapters (7; 8) of a second measuring device to the air conditioner after an extended period of time, and comparing the test results thereof with the results of the first test, whereupon the air conditioner is deaerated and separated from the adapters (7; 8) of the second measuring device.

摘要： Water pressure is monitored in a system. A first condition is detected when the water pressure has dropped below a predetermined value. In response to detecting the first condition, additional water is introduced into the system. A second condition is detected when said first condition has been detected as occurring for too long or occurring too often. Water is prevented from being introduced upon detecting the second condition.
