Abstract
A device comprises a sensor tube for placement in a process flow and a flow-modifying element. The flow-modifying element is formed on the sensor tube, in order to reduce flow-induced vibrations by reducing coherent vortex shedding in the process flow.
Claims35
A device comprising:
- a sensor tube for placement in a process flow;
- and
- a flow-modifying element formed on the sensor tube to reduce flow-induced vibrations of the sensor tube by reducing coherent vortex shedding in the process flow.
A sensor comprising:
- a sensor element for generating a sensor signal as a function of a process parameter;
- a sensor tube for communicating the process parameter to the sensor;
- a mounting assembly for mounting the sensor tube in a process flow;
- and
- a vibration-reducing element on the sensor tube for reducing vibrations induced by the process flow.
2 more elements
A method of making a sensor tube, the method comprising:
- forming a sensor tube;
- and
- forming a spiral flow-modifying element about the sensor tube, wherein the flow-modifying element is shaped to reduce flow-induced vibrations by disrupting coherent vortex shedding from the sensor tube when mounted in a process flow.
A method of monitoring a process parameter, the method comprising:
- positioning the sensor tube in a process flow, the sensor tube having a helical flow-modifying element configured to disrupt coherent vortex shedding from the sensor tube;
- sensing the process parameter with a sensor positioned for communication with the sensor tube.
