Device, method and system for monitoring a network of fluid-carrying conduits
First Claim
1. A liquid-flow monitoring device configured to monitor the flow of liquid in a conduit, the device comprising a sampler, a processor, a memory, and a communication module, wherein:
- the sampler is configured to receive data substantially continuously from a sensor indicative of at least one variable sensed by the sensor indicative of fluid flow in a conduit and to sample the data to produce a stream of sampled data;
the processor is configured to process the stream of sampled data to extract summary information and at least one sub-sampled stream therefrom, the sub-sampled stream comprising a plurality of data sets, each data set being a statistical subset of the stream of sampled data over a respective data-set period;
the memory is configured to store the at least one sub-sampled stream; and
the communication module is configured to periodically transmit the summary information to a central location remote from the device and, upon receiving a request for a more complete representation of the stream of sampled data at or over a specified time, to transmit one or more data sets corresponding to the specified time to the central location.

Abstract
A liquid-flow monitoring device (10) arranged to monitor the flow of liquid in a conduit. The device (10) comprises sampling means (20), processing means (30) and data storage means (40). The sampling means is arranged to receive data substantially continuously from a sensor (12) indicative of at least one variable sensed by the sensor (12) indicative of fluid flow in a conduit and to sample the data to produce a stream of sampled data. The processing means (30) is arranged to process the stream of sampled data to extract at least one sub-sampled stream therefrom, the sub-sampled stream comprising a plurality of data sets, each data set being a statistical subset of the stream of sampled data over a respective data-set period. The data storage means (40) is arranged to store the at least one sub-sampled stream.

9. A method of monitoring the flow of liquid in a conduit, the method comprising the steps of a liquid-flow monitoring device:
-
receiving data substantially continuously from a sensor, the data indicative of fluid flow in a conduit, and operating a sampler of the device to sample the data to produce a stream of sampled data; processing, using a processor of the device, the stream of sampled data to extract summary information and at least one sub-sampled stream therefrom, the sub-sampled stream comprising a plurality of data sets, each data set being a statistical subset of the stream of sampled data over a respective data-set period; storing, using memory of the device, the at least one sub-sampled stream; periodically transmitting, using a communication module of the device, the summary information to a central location remote from the device; and upon receiving a request for a more complete representation of the stream of sampled data at or over a specified time, transmitting one or more data sets corresponding to the specified time to the central location. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
