摘要： Single-jet fluid flowmeter that has a volume measurement error within metrological parameters in the range of 4 1/h and 5,000 1/h, is stable against hydraulic accidents upstream of the flowmeter, calcareous deposits, and allows tolerances that do not affect the metrological parameters. This flowmeter comprises a turbine, two nozzles and a measuring chamber. At least one of the nozzles forms an angle with the original direction of fluid flow of between 10° and 20°. The measuring chamber comprises a set of four upper ribs and six lower ribs, radially arranged and spaced at regular intervals. The ratio between the height at which the upper ribs project from the chamber varies between 1.5 and 1.7 times that of the lower ribs. Together with the abovementioned flowmeter, a measurement process is provided that incorporates this flowmeter onto an inlet duct and an outlet duct wherethrough the fluid is made to flow, and incorporates a counting element onto the flowmeter.

摘要： A flow meter for determining a flow rate of a flow of fluid, comprising: a turbine for immersion in the flow of fluid; a driving means for driving movement of the turbine; and a control system for varying the power supplied to the turbine by the driving means, wherein: the flow meter is configured to determine the flow rate by monitoring the operation of at least one of the turbine and driving means. The control system may vary the power until a disturbance caused to the flow by the meter is substantially minimized, with the flow meter using the characteristics of that state to determine a flow rate.

摘要： A system, method and program for calculating a fluid flow volume within a conduit having an operably connected flow meter is disclosed. The system includes a controller having a backplane. A flow meter module is operably connected to the backplane of the controller and to the flow meter. A program embedded within the controller is also operably connected to the flow meter. The program includes a plurality of segments for sensing a characteristic of the fluid for determining the flow volume of the fluid. The controller, in cooperation with the flow meter module, monitors the dynamic fluid density of the fluid in the conduit. The controller utilizes the dynamic density to determine a correction factor to more accurately calculate the fluid flow volume through the conduit.

摘要： The present invention relates to a system and a method for compensating for predicted meter drift in a positive displacement meter comprising: a pulser connected to the meter for generating a pulse stream indicative of a current volume delivered through the meter; and a pulse processor in electronic communication with the pulse generator. The pulse processor adds or subtracts pulses indicative of the inverse of the predicted meter drift to or from the pulse stream to create a corrected pulse stream. The amount of inverse applied is determined by the value of the current cumulative volume passed by the meter.

摘要： A gas turbine meter (20) includes a measuring cartridge (36) which has a measuring rotor (38) that rotates in one direction at a speed approximately proportional to the velocity of gas flowing through the meter (20) and a reference rotor mounted downstream of the measuring rotor (38) which rotates in the opposite direction from the measuring rotor. An inlet flow straightener (28) upstream of the measuring rotor causes gas to flow substantially axially within the meter, and a reference flow straightener mounted between the measuring rotor and the reference rotor also causes gas to flow substantially axially within the meter. A signal processor provides an indication of the accuracy of the gas turbine meter based on the quotient of a measuring signal, which is proportional to the speed of rotation of the measuring rotor, divided by a reference signal, which is proportional to the speed of rotation of the reference rotor.
