Abstract
A non-intrusive pressure sensor and method for measuring pressures within a pipe includes a displacement based sensor disposed on a surface of the pipe. The displacement based sensor measures the radial displacement response of the surface of the pipe to the unsteady pressure. The displacement based sensor may comprise an accelerometer, an absolute velocity sensor, or an absolute displacement sensor. One or more of sensors may be axially distributed along the pipe or alternatively the sensors may be circumferentially distributed about the pipe.

A system for measuring a naturally occurring unsteady pressure of a fluid flowing within a pipe, comprising:
- a pipe displaced only by the naturally occurring unsteady pressure of the fluid flowing within the pipe;
- and
- a displacement sensor disposed on a surface of the pipe for measuring a displacement response of the pipe to the naturally occurring unsteady pressure of the fluid flowing within the pipe and for providing a signal proportional to the naturally occurring unsteady pressure.
A system for measuring a naturally occurring unsteady pressure of a fluid flowing within a pipe, comprising:
- a pipe displaced only by the naturally occurring unsteady pressure of the fluid flowing within the pipe;
- and
- a plurality of displacement sensors disposed on a surface of the pipe, each sensor measuring a displacement response of the pipe to the naturally occurring unsteady pressure of the fluid flowing within the pipe and for providing a signal proportional to the naturally occurring unsteady pressure.
A method for measuring the naturally occurring unsteady pressure of a fluid flowing within a pipe, comprising:
- displacing the pipe using only the naturally occurring unsteady pressure of the fluid flowing within the pipe;
- measuring a displacement response of a surface of the pipe in response to the naturally occurring unsteady pressure with a displacement sensor;
- and
- providing a signal proportional to the naturally occurring unsteady pressure.
