Abstract
A system and method for substantially coincidental sample takeoff flow rate verification which detects unstable flow conditions in a pipeline, terminates fluid sample analysis during flow instability, and resumes sample takeoff when a steady flow state is re-established.
Claims19
A sample takeoff system for fluids in a pipeline comprising:
- a sample takeoff probe;
- a power-operated valve associated with said sample takeoff probe for controlling sample takeoff by the probe;
- and
- a sensor of fluid flow status in the pipeline located proximately to the sample takeoff probe for detecting the stability of fluid flow in the pipeline, said sensor configured to generate at least one control signal communicated to said power-operated valve to terminate sample takeoff from the pipeline during fluid flow instability.

A fluid pipeline sample takeoff system for substantially coincidental flow rate verification, comprising:
- a sample takeoff probe;
- a sensor for detecting the presence of anomalies generated by at least one unstable flow condition of the fluid in the pipeline and generating a signal representative thereof;
- a controller configured to receive the signal and determine if the signal exceeds a select threshold;
- and
- an electro-mechanically actuated valve associated with the sample takeoff probe and in signal communication with the controller, said electro-mechanically actuated valve configured to terminate fluid sample extraction upon detection of a threshold exceeding signal and to resume fluid sample extraction from the pipeline upon receipt of a signal not exceeding the select threshold and indicative of reestablishment of a substantially steady flow state.

A method for selectively actuating fluid sample extraction by a probe from a pipeline, comprising:
- detecting flow conditions of a fluid in a pipeline;
- generating a detection signal corresponding to a detected signal generated by flow conditions of the fluid in the pipeline;
- communicating the detection signal to a controller which determines if the detection signal exceeds a pre-select threshold indicative of fluid flow instability;
- and
- causing a power operated valve to terminate sample fluid extraction from the pipeline upon detection of a threshold exceeding signal and to resume sample fluid extraction upon detection of a signal less than the pre-selected threshold corresponding to substantially steady state fluid flow.
