Abstract: A vibratory meter (5) is provided, having a driver (104) and a vibratory member (103, 103′) vibratable by the driver (104). At least one pickoff sensor (105, 105′) is configured to detect vibrations of the vibratory member (103, 103′). Meter electronics (20) comprise an interface (301) configured to receive a vibrational response from the at least one pickoff sensor (105, 10540 ), and a processing system (303) coupled to the interface (301). The processing system (303) is configured to measure a drive gain (306) of the driver (104), and measure a total density (325) of a multiphase process fluid in the vibratory meter (5), and determine whether the drive gain (306) is below a first threshold. A liquid/liquid phase concentration allocation is determined with the measured total density (325) if the drive gain (306) is below the first threshold, and a flow rate for each liquid phase is calculated.

Abstract: A meter electronics (20) for selecting a measurement correction method is provided. The meter electronics (20) comprises an interface (501) configured to communicatively couple to a sensor assembly (10) and receive sensor signals from the sensor assembly (10) and a processing system (502) communicatively coupled to the interface (501). The processing system (502) is configured to store two or more measurement correction methods, wherein the two or more measurement correction methods compensate for multiphase effects of a multiphase fluid in the sensor assembly, determine one or more process parameter values, and select one of the two or more measurement correction methods based on the one or more process parameter values.

Abstract: A vibratory meter (5, 200) is provided, having a driver (104, 202) and a vibratory member (103, 103′, 204) vibratable by the driver (104, 202). At least one pickoff sensor (105, 105′, 209) is configured to detect vibrations of the vibratory member (103, 103′, 204). Meter electronics (20) comprise an interface (301) configured to receive a vibrational response from the at least one pickoff sensor (105, 105′, 209), and a processing system (303) coupled to the interface (301). The processing system (303) is configured to measure a drive gain (306) of the driver (104, 202) and determine a solute added to the fluid is substantially fully dissolved based upon the drive gain (306).

Abstract: A method of determining vapor pressure of a fluid is provided. The method comprises the step of providing a meter having meter electronics, wherein the meter comprises at least one of a flowmeter and a densitometer. A process fluid is flowed through the meter. A low-pressure location associated with the meter is provided. The pressure of the process fluid is adjusted until flashing is detectable at the low-pressure location. The true vapor pressure of the process fluid is calculated at an instant where flashing is detected.

Abstract: A method of determining vapor pressure of a fluid is provided. The method includes the steps of providing a meter (5) having meter electronics (20), the meter (5) being at least one of a flowmeter and a densitometer, and flowing a process fluid through the meter (5). A pressure of the process fluid is measured. The pressure of the process fluid is adjusted until a monophasic/biphasic boundary is reached. The flowing vapor pressure of the process fluid is determined at the monophasic/biphasic boundary.
