Abstract
A system includes a safety system having one or more valves configured to block a flow of fluid from a source to a destination, a non-invasive pressure measurement system having a plurality of non-invasive pressure sensors configured to monitor a pressure of the fluid without directly contacting the fluid, and a controller configured to receive feedback from the non-invasive pressure measurement system and to adjust a position of the one or more valves of the safety system based on the feedback.
Claims19
A system, comprising:
- a safety system comprising one or more valves configured to block a flow of fluid from a source to a destination;
- a non-invasive pressure measurement system comprising a plurality of non-invasive pressure sensors configured to monitor a pressure of the fluid without directly contacting the fluid, wherein a non-invasive pressure sensor of the plurality of non-invasive pressure sensors comprises a strain gauge, and wherein the strain gauge is disposed in a recess formed in a conduit configured to flow the fluid from the source to the destination, wherein the recess is positioned downstream of the safety system with respect to the flow of the fluid through the conduit, wherein the strain gauge is configured to measure a mechanical stress to the conduit caused by the pressure of the fluid, and wherein the mechanical stress is indicative of the pressure of the fluid;
- and
- a controller configured to receive feedback from the non-invasive pressure measurement system and to adjust a position of the one or more valves of the safety system based on the feedback.

A system, comprising:
- a safety system disposed along a conduit configured to direct a fluid from a source to a destination, wherein the safety system comprises one or more valves configured to block a flow of the fluid to the destination when the one or more valves are in a closed position;
- a sensor adapter fluidly coupled to the conduit, wherein the sensor adapter is configured to be disposed between a first segment of the conduit and a second segment of the conduit, wherein the sensor adapter comprises a cavity extending into a wall of the sensor adapter from an external surface of the sensor adapter, and wherein the sensor adapter comprises a recessed portion extending radially into the wall from an interior surface of the sensor adapter;
- a non-invasive pressure measurement system coupled to the sensor adapter, wherein the non-invasive pressure measurement system comprises a plurality of non-invasive pressure sensors, wherein a non-invasive pressure sensor of the plurality of non-invasive pressure sensors comprises a capacitance based pressure sensor, wherein the non-invasive pressure measurement system is configured to monitor a pressure of the fluid without directly contacting the fluid, wherein the capacitance based pressure sensor comprises a core and an insulative material disposed in the cavity of the sensor adapter to form a capacitor, the capacitance based pressure sensor is configured to measure changes in capacitance of the capacitor as a distance between the core and a surface of the cavity changes due to the pressure of the fluid in the recessed portion of the sensor adapter, and wherein the changes in capacitance of the capacitor are indicative of the pressure of the fluid;
- and
- a controller configured to receive feedback from the non-invasive pressure measurement system and to adjust a position of the one or more valves of the safety system based on the feedback.
