Title: Apparatus and method for measuring two or three phase fluid flow utilizing one or more momentum flow meters and a volumetric flow meter
Inventor: FARCHI DAVID
IPC: G01F1/74
Filed: 1993-03-11
Granted: 1999-02-02
Abstract: An apparatus and method for measuring the flow rates of each component of two-phase now consisting of a gas and a liquid or three-phase flow consisting of water, oil and gas, including a first volumetric flow meter stage, and second and third momentum flow meter stages coupled in a series flow path with the volumetric flow meter stage and in which a velocity ratio between the gas and the liquid in the series flow path is maintained to be one. A processor calculates flow rates of the components of flow by solving volumetric flow and momentum or energy equations defining flow through the first through third stages utilizing a volumetric flow output from the first stage and momentum flux outputs from said second and third stages, and an indicator displays flow of liquid and gas or oil, water and gas components of the flow. To measure three-phase flow, a water-cut meter is provided to determine the amount of water flow, which is then used by the processor to determine the flow of the rest of the liquid. The second and third momentum flow meter stages can be implemented by two separate momentum flow meters or by a single momentum flow meter, such as a venturi flow meter having a venturi nozzle including pressure taps for obtaining at least two differential pressure measurements. In the event that the density or the liquid component is known, a single momentum flow meter stage is sufficient.

Abstract: Analog signals representing individual digital values (+3,+1, -1,-3) of data pass through a telephone line to a receiver. These signal may first be provided in a pseudo random sequence. A linear echo canceller and a first adder at the receiver simultaneously eliminate, to some extend, echo signals resulting from second analog signals transmitted through the telephone line by the receiver. A non-linear echo canceller and a second adder further  significantly reduce the echo signals and specifically reduce non-linear components in the echos signals. Adjustable signal delays achieve optimal performance of the linear and non-linear echo cancellers. In one inventive embodiment, each echo canceller includes a memory which stores, for each terminal in such echo canceller, data representing (a) the pseudo random sequence and (b) coefficients for adjusting the signals in such sequence. Such data for each terminal in such echo canceller is recorded in the memory for introduction to the next terminal in the memory.    For each terminal in such echo canceller, the signals representing the data for the coefficient and the output from the associated adder are processed to determine an adjusted value of such coefficient for storage in the memory and for use in the next cycle of processing. The adjusted coefficient value and the data stored in the memory for such terminal are processed to produce signals for introduction to the associated adder. The signals from the second adder are processed to restore the data transmitted through the telephone line to the receiver.

The radius of curvature and the center of curvature lie inside the curve so that a convex curve is obtained. The cord (114) is further characterized by one or both of the following features: (i) the distance between two minimum radii of curvature of said curve measured along the longitudinal central axis (112) is different from half the cord pitch; or (ii) if all of said elements (100) provide a convex curve, at least one of said convex curves substantially differs from another convex curve. The steel cord (114) allows full rubber penetration despite low values of cord diameter and part load elongation (PLE).
