    摘要： The invention describes a system for monitoring the leak-tightness of a tank (101), which is filled with a liquid (200) with a lower density than that of water, and which has a liquid run-off pipeline (100, 102), with a container (1) which has a bottom well (13) and is integrated horizontally in the liquid run-off pipeline (100, 102), and with a baffle element (5), which divides the container (1) into a partial region (12) on the run-in side and a partial region (11) on the run-out side. A first vibrational measuring device (3), with a first vibratory unit (31) protruding into the partial region (12) on the run-in side of the bottom well (13), determines whether the density of the medium is below a predetermined limit value, a second vibrational measuring device (4), with a second vibratory unit (41), detects whether the vibratory units (31, 41) are covered with medium, and an evaluation unit (6) ascertains on the basis of the measured values of the measuring devices (3, 4) whether there is liquid (200) from the tank (101) in the container (1).

    摘要： The invention relates to a leak warning system for double-walled fluid lines (4) or tanks (2), in particular in filling stations (1), comprising a pressure fluid reservoir (7) for pressurising the cavity (6) of the double wall with pressure medium, a first pressure sensor (9) for measuring the cavity pressure (p
    o ), a second pressure sensor (10), for measuring the internal pressure (p
    i ) of the fluid line (4) or tank (2), a controllable valve (8) between the pressure fluid reservoir (7) and the cavity (6), a regulator (13) connected to the pressure sensors (9, 10) for controlling the valve (7) with the regulation purpose being to hold the cavity pressure (p
    o ) at a minimum pressure difference (p
    diff,min ) above the internal pressure (p
    i ) and an analytical unit (15) connected to the pressure sensors (9, 10) which gives a leak warning when the pressure difference between the cavity pressure (p
    o ) and the internal pressure (p
    i ) exceeds the minimum pressure difference (p
    diff,min ).

    摘要： An apparatus for detecting a leak in a conduit line includes a housing in fluid communication with the line, a valve including a valve seat and a valve element movable relative to the seat between opened and closed positions, a bypass line around the valve, a flow detector coupled to the bypass line for detecting fluid flow therethrough, and a first mechanism configured to urge the valve element toward the closed position. The apparatus may further include a second mechanism separate from the first mechanism for maintaining the valve element in the closed position until a threshold pressure drop is reached. The first mechanism may operate on the principle of buoyancy and the second mechanism may operate on the principle of magnetism.

    摘要： A leak detector (20) for detecting volumetric changes in a liquid volume includes a biased piston (42) disposed in a housing (30) and a liquid passage (38) extending from the liquid volume to an expansible chamber (41) defined by the housing (30) and piston (42). The leak detector (20) further includes a magnetostrictive sensor (66) including a magnetostrictive waveguide (68), a magnet (70) operably coupled to the piston (42) and moveable therewith and pulsing and detection devices for detecting the position of the magnet (70) along the magnetostrictive waveguide (68). A method of using the detector (20) includes exposing the expansible chamber (41) to liquid from the liquid volume and sensing the changes in the liquid volume magnetostrictively by causing relative movement between the waveguide (68) and the magnet (70) to obtain data representative of piston movement which is responsive to volumetric changes in the liquid volume.

    摘要： A leak detection system and a method of detecting leaks are disclosed for detecting a leak in a system, including a pump, a dispenser, a conduit communicating the pump and the dispenser, and a valve in the conduit. The valve includes an electronic flow measurement device for detecting leaks in the system downstream of the device.
    The system may be operated by a control circuitry, which indicates a predetermined flow of fluid indicating a leak. The present invention is also directed to a method of detecting a leak in a system having a fluid pump, a dispenser, a conduit connecting the pump and the dispenser, a valve in the conduit, and an electronic flow detection system in the valve. The valve is provided with an orifice communicating the conduit with the electronic flow detection system.
    The method includes the steps of activating the pump and opening the dispenser to dispense a fluid, and then closing the dispenser while continuing the activation of the pump thereby increasing fluid pressure in the conduit. The increase in fluid pressure causes the valve to close, thus isolating the pump from the dispenser except for the orifice in the valve. The electronic fluid detection system senses the flow of fluid through the orifice.
