摘要： 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.

摘要： A damping device for a fluid flow meter mountable on the exterior of a pipe to meter fluid flow traveling within the pipe is provided. The flow meter has at least one ultrasonic sensor operable to transmit ultrasonic signals through a pipe wall in a direction normal to the pipe wall and into a fluid flow disposed within the pipe, which signals create secondary ultrasonic signals circumferentially traveling within the pipe wall at a frequency. The damping device includes a base and a plurality of tines. The base is conformable to an exterior surface of the pipe wall, and has a pipe-side surface and a tine-side surface. The plurality of tines is attached to the base and extends outwardly from the tine-side surface. Each tine is spaced apart from an adjacent tine by a tine-to-tine distance that is less than the wavelength of the secondary ultrasonic signals circumferentially propagating within the pipe wall.

摘要： A method and apparatus for measuring wetness of a gas flow within a conduit is provided that includes a first pressure sensor, a second pressure sensor, a sonar based flowmeter, and a processing device. The first pressure sensor is operable to sense the pressure of the gas flow within the conduit at a first position. The second pressure sensor is operable to sense the pressure of the gas flow within the conduit at a second position. The second position is located downstream of the first position an amount sufficient that the gas flow experiences a pressure drop. The sonar based flowmeter is configured to determine a volumetric flow rate of the gas flow. The processing device is in communication with the first and second pressure sensors and the sonar based flowmeter. The processing device is adapted to determine a difference in the pressure sensed by the first and second pressure sensors, and to determine the wetness of the gas flow using the difference in pressure and the volumetric flow rate.
