  • Patent number: 10677766
    Abstract: A multi-dimensional liquid analysis system includes a first dimension system and a second dimension system, wherein outflow from the first dimension system is separated at a flow splitter under controlled conditions. The flow splitter separates the first dimension outflow into first and second split outlet flows, with one of the split outlet flows being metered to a designated flow rate with a flow metering device disposed downstream from the flow splitter. The flow metering device selectively closes or opens an outlet flow path to define a volumetric flow rate along that outlet flow path, so that the other split outlet flow is correspondingly controlled.

  • Patent number: 10620090
    Abstract: A first determination unit performs a process (first process) of sequentially dividing an intensity value constituting first data by a reference intensity value to calculate an intensity ratio and determining whether the intensity ratio exceeds a first threshold (steps S3 and S4). When a predetermined period has elapsed, a second determination unit calculates an average change rate of the first data in the predetermined period to determine whether the average change rate is within a predetermined range (steps S9 and S10). When it is determined that the average change rate is within the range, the reference intensity value is updated and lowered (step S11). When the reference intensity value is updated, the first determination unit performs the first process by using the updated reference intensity value in the next predetermined period.

    Abstract: A meter verification method for a vibratory flowmeter (5) is provided, comprising vibrating a sensor assembly (10) of the vibratory flowmeter (5) with a plurality of test tones in a vibration mode using a driver (180), wherein the plurality of test tones is applied substantially instantly, in the absence of a ramp function. A driver (180) current is determined, and response voltage of pickoff sensors (170L, 170R) are determined for the vibration mode. The instantaneous frequency of the pickoff sensor (170L, 170R) signals is measured, and a filter is applied to isolate the response at each of the plurality of test tones. The filter is also applied to the instantaneous frequency measurements. The same delay is applied to the frequency measurements and the response at each of the test tones. A meter stiffness value (216) is generated using the current (230) and the response voltage (231), and proper operation of the vibratory flowmeter (5) is verified using the meter stiffness value (216).
