摘要： An automatic fluid-sensing and fluid shut-off system (10) that allows a flow of water into a structure to be sensed, timed and stopped when the flow exceeds a preset time. The system (10), which operates in combination with a conventional main water valve (50) and pressure regulator (60), consists of a flow-sensing valve (12) that incorporates an infrared emitter (14) and an infrared detector (16), an electric valve (18) and an electronics control unit (20). When a flow is sensed by the valve (12), the detector (16) produces a flow-trigger signal that is applied to a programmable timer (20n) in the unit (20). When the signal is received, the timer commences a countdown; when the time has lapsed, the unit (20) produces a signal that energizes a power relay (20h) that removes the power keeping the electric valve (18) open. Upon this power removed, the valve (18) closes and shuts off the water supply. The water flow remains off until the system is reset by depressing a reset switch (20t).

摘要： The invention relates to a fluid flow monitor and control system which prevents excessive fluid loss and property damage. The invention warns of impending distribution pipe freeze conditions, or ruptures from other causes, shuts off the fluid supply, and vents and drains the piping network under freeze and rupture conditions. Furthermore, the invention shuts off fluid flow if the volume of flow or the velocity exceeds desired norms. An example of its application is as a water main shut-off for residential houses and commercial buildings, it also can be used for industrial processing applications.

摘要： A method and apparatus for measuring a gas pressure gradient in each of the upstream and downstream parts of a gas pipe line and detecting a leak in the gas pipe line in accordance with the pressure gradients. When a gas leak occurs, the gas pressure at the position of the leak is decreased and at least the pressure gradient upstream of this position is increased. When the difference between the upstream pressure gradient and the downstream pressure gradient is greater than a predetermined value, the occurrence of a gas leak is determined. Also, the occurrence of a gas leak is determined when each of the displacement of the upstream pressure gradient and the displacement of the downstream pressure gradient attains a predetermined relation.

摘要： A system is disclosed which indicates a series of intermittent losses of fluid between any two stations along a fluid flow system such as a refinery or pipeline. The series of intermittent losses relates to a chain of intervals of operation of the fluid flow system. A sudden disturbance in the operation of the fluid flow system during an interval of operation is smoothed over a selectively variable number of intermittent loss indications in the series rather than reflected entirely in the intermittent loss indication for the interval of operation in which the sudden disturbance occurs. On the other hand, actual changes in the operation of the fluid flow system are averaged over the selectively variable number of intermittent loss indications in the series so that rapid changes as well as gradual changes in the operation of the fluid flow system result in a trend in the series of intermittent losses. This permits personnel to reliably monitor the fluid flow system and, therefore, facilitates repair or adjustment of the operation of the fluid flow system only when it is needed. The system also provides an overall loss indication for a period in the operation of the fluid flow system based on the total amount of fluid input to and output from the fluid flow system. The system determines the beginning of the overall loss period by indicating a predetermined status in the operation of the fluid flow system. The system determines the end of the overall loss period by indicating a return in the operation of the fluid flow system to the predetermined status. This eliminates error in the overall loss indication. The system also provides correlation of fluid flow meters during the operation of the fluid flow system.
摘要翻译：公开了一种系统，其指示沿着流体流系统（例如炼油厂或管道）的任何两个站之间的一系列间歇性流体损失。一系列间歇性损失涉及流体流动系统的一系列操作间隔。在操作间隔期间流体流动系统的操作突然的干扰在该系列中的选择性可变数量的间歇性损失指示上平滑化，而不是完全反映在发生突然干扰的操作间隔的间歇损失指示中。另一方面，流体流动系统的操作的实际变化是在该系列中的间歇性损失指示的选择性可变数量上进行平均化，使得流体流动系统的快速变化以及逐渐变化的流体流动系统产生趋势在一连串的间歇性损失。这允许人员可靠地监测流体流动系统，因此仅在需要时便于维修或调整流体流动系统的操作。该系统还基于输入到流体流动系统和从流体流动系统输出的流体的总量，在流体流动系统的操作期间提供整体损失指示。系统通过在流体流动系统的操作中指示预定状态来确定整个损失周期的开始。该系统通过指示流体流动系统的操作返回到预定状态来确定整个损失周期的结束。这消除了整体丢失指示的错误。该系统还提供流体流动系统运行期间流体流量计的相关性。

摘要： Discloses a check valve and a leak indicator for indicating the position of a valve closure means relative to spaced apart inlet and outlet ports. The invention involves the use of an elongated cylindrical valve chamber and a spring loaded valve closure mounted therein for reciprocating movement between the inlet and outlet ports, so as to require maximum axial movement to open the outlet port. Magnetic indicating means situated outside the valve housing and outside the valve chamber are completely isolated and separated from the fluids in the valve chamber, and move responsive to the axial movement of the reciprocating valve closure to indicate the smallest leak.

摘要： There is disclosed herein an electronic monitoring system for pipelines and the like utilizing counting techniques for determining the difference between fluid volume supplied into a pipeline and the fluid volume removed from the pipeline. An error factor is employed and, based upon the volume difference, provides compensation for normal difference between the input and output volume measuring devices. This error factor then compensates for the normal difference between input and output volume. Abnormal deviations can then be detected to determine fluid leaks and the like for actuating alarm and control circuits for providing an alarm and/or terminating fluid flow in the pipeline system. There is also disclosed herein the manner in which the present electronic system can be utilized for monitoring a pipeline system with multiple input meters or outputs meters. There is also disclosed herein methods for precisely determining the normal difference between input and output meters.
