摘要： A method for calibrating a flowmeter is provided that comprises determining a relationship between tube period ratio and a flow tube temperature compensation (FTC) value for a plurality of flowmeters. Tube periods of the flowmeter under test are measured. A stiffness-correlated FTC is calculated using the determined relationship between the tube period ratio and the FTC value for the plurality of flowmeters and the measured tube periods of the flowmeter under test. The stiffness-correlated FTC is applied to an operating routine (314) of the flowmeter under test.

摘要： A method for correcting a flow variable (509) based on an inner pressure inside a Coriolis flow meter (202) comprises the steps of receiving a first outside pressure (503) measured with a first pressure sensor (204) located in a first process conduit (208a) positioned on a first end (212a) of the Coriolis flow meter (202), determining a second outside pressure (505) in a second process conduit (208b) positioned on a second end (212b) opposing the first end (212a) of the Coriolis flow meter (202), determining an estimated inner flow meter pressure (507) based on the first outside pressure (503) and the second outside pressure (505), receiving the flow variable (509), and generating a corrected flow variable (512) based on the estimated inner flow meter pressure (507), a pressure compensation factor (510), and the flow variable (509).

摘要： A method for inferring an inferred speed of sound of a flow fluid is disclosed. The method is conducted by a computer system (200) having a processor (210) and a memory (220), the processor (210) configured to execute instructions from the memory (220) and store data in the memory (220), the memory (220) having a SoS inference module (202). The method includes inferring, by the SoS inference module (202), the inferred speed of sound of the flow fluid based on an inferential relationship between a measured density of the flow fluid and the inferred speed of sound of the flow fluid.

摘要： The method comprises producing a measurement signal (s1) having a signal parameter, followed with a temporal change (Δx1/Δt; Δx1′/Δt) of a primary measured variable (x1) and a temporal change (Δy1/Δt) of a disturbing variable (Δ1), and producing a measurement signal (s2) having a signal parameter, followed by a temporal change (Δx2/Δt; Δx2′/Δt) of a primary measured variable (x2). The method comprises ascertaining measured values (XI) of first type representing the primary measured variable (x1) or a secondary measured variable (f(x1) Δx1′) of measured values (XII) of second type representing the primary measured variable (x2) or a secondary measured variable (f(x2) Δx2′). The method comprises using measured values (XI) of first type and measured values (XII) of second type for ascertaining an error characterizing number (Err) representing a velocity error (ΔXI/ΔXII) caused by a change of the disturbing variable (y1).

摘要： Techniques for monitoring a well clean-up process are disclosed. In one embodiment, a method includes routing a multiphase fluid having oil and water to a separator of a well testing apparatus, separating the multiphase fluid into separate fluids via the separator, and routing the separated fluids away from the separator. The method also includes measuring flow rates of oil and water leaving the separator and determining individual flow rates of oil and water entering the separator as part of the multiphase fluid based on the measured flow rates of oil and water leaving the separator. Additional systems, methods, and devices are also disclosed.

摘要： Vibratory meters (5), and methods for their use measuring a fluid are provided. Each vibratory meter includes a multichannel flow tube (300) comprising two or more fluid channels (302), a pickoff (170), a driver (180), and meter electronics (20) configured to apply a drive signal to the driver at a drive frequency ω, and measure a deflection of the multichannel flow tube with the pickoff. In examples, at least one fluid channel has an effective diameter that is related to velocity of sound and drive velocity. In further examples, the driver may apply a drive signal to the driver having a drive frequency proportional to the velocity of sound and effective diameter.
