    • The apparatus is used for testing heat exchangers having mutually separate first and second flow paths. The apparatus provides a high pressure fluid source (10) to connect with a first pressure-sealed flow path of the heat exchanger under test.A volumetric sensor (VS) is connected to a selected pressure-sealed flow path, having a sensing chamber arranged to receive fluid from the selected flow path. The sensing chamber is connected to a further fluid source such as a compressed air reservoir (16) which provides a high pressure gas supply. Movement of a magnetic float within the sensing chamber is detected by an array of Hall effect sensors, enabling a CPU to calculate the rate of leakage between the two flow paths which may be signaled to a local display and/or alarm or remotely via an internet connection.

    • The liquid sensing system for an aircraft cooler includes a middle liquid level sensor for detecting a middle liquid level of a working fluid, a liquid temperature sensor, a ventilation controller for generating a flight phase signal indicative of a flight phase of the aircraft, and a recirculation unit annunciating a working fluid system leak condition based on the middle liquid level, the liquid temperature, and the flight phase. The recirculation unit only evaluates the working fluid system leak condition during a ground flight phase and a cruise flight phase. A bottom liquid level, pressure in a working fluid accumulator and discharge pressure are also determined, and a no working fluid failure condition is annunciated based an the bottom liquid level signal, the accumulator pressure signal, and the discharge pressure signal.
