    摘要: A method for determining an air flow in a vehicle air conditioning system, the system comprising: at least one inlet; a plurality of outlets; at least one air duct for guiding air from the inlet to the outlets, each air duct being characterized by a predetermined flow resistance coefficient; at least one flap being characterized by a flow resistance based on a degree of opening of the flap; and a fan for creating an air flow from the inlet to an outlet; the method comprising the steps of; determining a total equivalent flow resistance between a predetermined location in the system and the interior of the vehicle; wherein flow resistances are treated as resistances in an electric circuit, and a total equivalent flow resistance is determined. Treating a pressure drop as equivalent with a voltage drop, the air flow can be determined, as the pressure is equal to the resistance times the flow squared.

    摘要: A method of and apparatus for assessing the condition of a fluid conduit. The method comprises providing a measurement apparatus comprising a measurement region in fluid communication with the fluid conduit. The measurement apparatus is operable to measure at least one of pressure and flowrate in the measurement region. A pressure surge is effected or generated to propagate in the fluid conduit, and at least one of a pressure response or a flowrate response from the fluid conduit is measured. From a pressure data set and a flowrate data set, a data set representative of the cross sectional area along the fluid conduit is determined. This enables average or over all area profiles along long fluid pipelines to be deduced.

    摘要: Technique of suppressing performance variations for each flow sensor is provided. In a flow sensor FS1 of the present invention, a part of a semiconductor chip CHP1 is configured to be covered with resin (MR) in a state in which a flow sensing unit (FDU) formed on a semiconductor chip CHP1 is exposed. Since an upper surface SUR (MR) of the resin (MR) is higher than an upper surface SUR(CHP) of the semiconductor chip (CHP1) by sealing the resin (MR) on a part of the upper surface SUR(CHP) of the semiconductor chip CHP1 in a direction parallel to an air flow direction, the air flow around the flow sensing unit (FDU) can be stabilized. Further, interface peeling between the semiconductor chip (CHP1) and the resin (MR) can be prevented by an increase of contact area between the semiconductor chip (CHP1) and the resin (MR).

    (a) a means (20, 22, 70, 90) for introducing a change of a known volume of liquid over a known time to the initial flow rate (Q);
    (b) a sensor (50, 50', 50", 72, 92) located downstream from the point for where a known liquid volume over a known time is introduced, the sensor (50, 50', 50", 72, 92) measuring a flow corresponding parameter; and
    (c) a controller (100) connected to the sensor (50, 50', 50", 72, 92), the controller (100) being configured to determine the initial flow rate (Q) in response to the relative change (Cd) in the flow corresponding parameter downstream from where the flow is changed and the introduced known liquid volume over a known time, corresponding to Q = Q i C d ,
    where Cd = ΔQd/Qd is the relative change in the measured flow corresponding parameter.
