摘要： A pressure sensing device is operable to monitor pressure variations within a fluid pipeline. The pressure sensing device comprises a pair of complementary sensor elements. At least one of the sensor elements is mounted to a supporting bracket that is mounted to a point on the external surface of the pipeline. At least one sensor element is mounted such that the pair of complementary sensor elements experience relative displacement as the external surface of the pipeline undergoes changes in size or shape. The pair of complementary sensor elements are operable to detect said relative displacement and thereby provide an indication of pressure variation within the pipeline.

摘要： According to the present invention, there is provided a method of monitoring a fluid in a fluid carrying conduit comprising the steps of: monitoring a fluid characteristic at a first point and second point along the conduit substantially continuously; determining first and second quantities, being related to a differential with respect to time of the value of the fluid characteristic at the first and second points respectively; combining the first and second quantities to produce a two dimensional intensity function of time and a position variable and analysing the magnitude of the intensity function to derive information relating to the fluid. The intensity function may represent a substantially continuous probability function, wherein its absolute value is related to the probability of a leak or theft having occurred in the conduit. Furthermore, a method of determining the presence and location of leaks in, or thefts from, the conduit by determining whether or not the magnitude of the intensity function satisfies pre-determined criteria is disclosed. A method of determining the speed of pressure waves propagating through a fluid flowing in a fluid carrying conduit by analysing the two dimensional intensity function is also disclosed. An apparatus suitable for performing all of the above mentioned methods is also claimed.
摘要翻译：根据本发明，提供了一种监测流体输送管道中的流体的方法，包括以下步骤：基本上连续地沿着管道在第一点和第二点监测流体特性; 确定第一和第二量，分别与第一和第二点处的流体特性的值相对于时间的差异相关; 组合第一和第二数量以产生时间和位置变量的二维强度函数，并且分析强度函数的大小以导出与流体相关的信息。强度函数可以表示基本上连续的概率函数，其中其绝对值与在导管中发生泄漏或盗窃的可能性有关。此外，公开了一种通过确定强度函数的大小是否满足预定标准来确定管道中的泄漏存在和位置以及来自导管的方法。还公开了一种通过分析二维强度函数来确定在流体输送导管中流动的流体传播的压力波的速度的方法。还要求保护适于执行所有上述方法的装置。
