Abstract: A system for the detection of a rate of flow or a level of a fluid or the presence of an object, such as a PIG, in pipelines, comprising at least one detection device that includes: a sensor assembly arranged to detect the rate of flow or level of a fluid withing a section of a pipeline or the presence of a pig located along the section of pipeline where the device is located, a power store, a position determining module, a radio frequency receiver, and a radio frequency transmitter, in which the detection device has a sleep mode in which the sensor assembly is inactive and has a first power consumption and an active mode in which the sensor assembly is active and the detection device has a second, higher, power consumption when the sensor assembly of the device is actively detecting, the device in the active mode also being arranged to transmit signals from the transmitter that are indicative of the detected property of the fluid or presence of an apparatus along the section of the pipeline; and in which the device is configured to switch between the sleep mode and the active mode in response to radio frequency signals received by the receiver.

Abstract: A system comprising: a reservoir (14) for holding a liquid; a pump (20) arranged to pump the liquid out of the reservoir (14) or into the reservoir (14); a level sensor (26) configured to detect the level of the liquid in the reservoir (14) and to generate level data; a current monitor (28) configured to monitor the current drawn by the pump (20) and to generate current data; and a controller (30) configured to: receive level data and determine the static head from the level data, and generate head data from the static head; receive first current and head data corresponding to the current drawn by the pump (20) as a function of the static head for a first period of operation of the pump (20); receive second current and head data corresponding to the current drawn by the pump (20) as a function of the static head for a second period of operation of the pump (20), wherein the second current and head data is recorded when the liquid in the reservoir (14) is between a first liquid level and a second liquid level, and wherein the first current and head data is recorded when the liquid in the reservoir (14) is between at least the first liquid level and the second liquid level; and process the first current and head data and the second current and head data to determine first difference data (PPI) representing the difference between the current drawn between the first liquid level and the second liquid level in the first period of operation and the second period of operation, the first difference data providing a pump performance indicator giving an indication of the condition of the pump.
