Patent ID: 8174398

Claim:
A sensor leak monitor device, interspersed in a pipeline, the device comprising: a pressure measuring device, communicatively coupled to a pipeline, capable of determining a steady state pressure of the pipeline contents and remembering said steady state pressure value, and of measuring a dynamic state pressure of the pipeline contents; a time-measuring device, capable of being preset to a plurality of discrete time settings and of being operated as a timer, controllable coupled to the pressure measuring device and operated such that upon the measured pressure deviating from the steady state pressure value to a lower pressure reading the time-measuring device is activated until it either the measured pressure returns to the steady state pressure value and then the time-measuring device resets itself to the preset time or the preset time is exhausted; at least one temperature measuring device, coupled to the pipeline, capable of determining whether the pipeline contents have fallen below a preset temperature value; an alarm device, capable of being triggered by the time-measuring device's expiration of a preset time and whenever the at least one temperature measuring device registers a temperature below a preset value; and a human interface control device, communicatively connected to the pressure measuring device, time-measuring device, at least one temperature measuring device, and alarm device, capable of controlling the time-measuring device and at least one temperature measuring device parameters and alarm device settings.
