Tracking vibrations in a pipeline network
View Patent ↗A vibration recorder for detecting leaks in a pipeline network includes a sensor operable to receive vibration signals from a pipeline network, and a communication port connected to an automatic meter reader/transmitter (“AMRT”). A processor connected to the communication port and to the sensor is programmed to process the vibration signals and to send data regarding the processed vibration signals to the AMRT using the communication port. The vibration recorder may also include metering functions, and, in some implementations, may also incorporate the functions of the AMRT.
