    摘要： By monitoring pressure transients in a liquid within a liquid distribution system using only a single sensor, events such as the opening and closing of valves at specific fixtures are readily detected. The sensor, which can readily be coupled to a faucet bib, transmits an output signal to a computing device. Each such event can be identified by the device based by comparing characteristic features of the pressure transient waveform with previously observed characteristic features for events in the system. These characteristic features, which can include the varying pressure, derivative, and real Cepstrum of the pressure transient waveform, can be used to select a specific fixture where a valve open or close event has occurred. Flow to each fixture and leaks in the system can also be determined from the pressure transient signal. A second sensor disposed at a point disparate from the first sensor provides further event information.

    摘要翻译： 通过仅使用单个传感器监测液体分配系统内的液体中的压力瞬变，可以容易地检测诸如特定固定装置处的阀的打开和关闭等事件。 可以容易地连接到水龙头围兜的传感器将输出信号传输到计算设备。 设备可以通过比较压力瞬态波形的特征与系统中事件的先前观察到的特征来识别每个这样的事件。 这些特征可以包括压力瞬变波形的变化压力，微分和真实倒谱，可用于选择发生阀门开启或关闭事件的特定夹具。 流向每个夹具和系统中的泄漏也可以从压力瞬态信号确定。 设置在与第一传感器不同的点处的第二传感器提供进一步的事件信息。

    摘要： A manifold trailer comprises at least one main line having a plurality of discharge connectors and a plurality of articulating arm assemblies which are each connected to a corresponding discharge connector. Each arm assembly comprises a connector member which includes an inlet port, an outlet port and a third port which is located generally opposite the outlet port and is closed by a removable plug member. Each arm assembly also includes an articulating conduit assembly which comprises a first end that is connected to the inlet port and a riser swivel which is connected to the outlet port. During deployment of the arm assembly, a second end of the conduit assembly is connectable to a pumping unit to thereby fluidly connect the pumping unit to the main line.
