摘要： Flow rate measurement system includes two measurement regions 14,16 located an average axial distance ΔX apart along the pipe 12, the first measurement region 14 having two unsteady pressure sensors 18,20, located a distance X1 apart, and the second measurement region 16, having two other unsteady pressure sensors 22,24, located a distance X2 apart, each capable of measuring the unsteady pressure in the pipe 12. Signals from each pair of pressure sensors 18,20 and 22,24 are differenced by summers 44,54, respectively, to form spatial wavelength filters 33,35, respectively. Each spatial filter 33,35filters out acoustic pressure disturbances Pacoustic and other long wavelength pressure disturbances in the pipe 12 and passes short-wavelength low-frequency vortical pressure disturbances Pvortical associated with the vortical flow field 15. The spatial filters 33,35 provide signals Pas1,Pas2 to band pass filters 46,56 that filter out high frequency signals. The Pvortical-dominated filtered signals Pasf1,Pasf2 from the two regions 14,16 are cross-correlated by Cross-Correlation Logic 50 to determine a time delay τ between the two sensing locations 14,16 which is divided into the distance ΔX to obtain a convection velocity Uc(t) that is related to an average flow rate of the fluid (i.e., one or more liquids and/or gases) flowing in the pipe 12. The invention may also be configured to detect the velocity of any desired inhomogeneous pressure field in the flow. The invention may also be combined with an instrument, an opto-electronic converter and a controller in an industrial process control system.

摘要： An apparatus and method for determining the water cut value of a multiphase fluid flowing within a pipe is provided. The device includes a sequestering structure disposed within the pipe, a transmitting device, a receiving device, and a processing device. The sequestering structure at least partially defines a sensing passage within the pipe, which passage has a gap extending substantially normal to a direction of fluid flow within the pipe. The sensing passage is oriented to sequester an amount of a liquid component of the multi-phase fluid sufficient to form a continuous liquid body extending across the gap of the sensing passage. The transmitting device is operable to transmit a signal through the liquid across the gap of the sensing passage. The receiving device is operable to receive the signal after it has traversed the liquid within the sensing passage, and create sensor data. The processing device is in communication with at least the receiving device to receive and process the sensor data to determine the water cut value of the liquid.
