摘要： A pump control system for a wet test meter (WTM) is disclosed. The pump control system includes a WTM that contains packing fluid, a control module that has a DC power supply and is configured to detect a level of the packing fluid in the WTM, a pump that is configured to be controlled by the control module and is activated when the packing fluid in the WTM falls below a predetermined level, and a level sensor/detector that is located outside of the WTM, wired to the control module, and configured to monitor the packing fluid level within the WTM. When the packing fluid falls below the predetermined level as detected by the control module, the WTM is automatically filled by pumping packing fluid from a storage tank using the pump, until the packing fluid level reaches above the predetermined level.

摘要： A method and apparatus for determining the flow rates of a multi-component fluid mixture is disclosed. The temperature and pressure of the multi-component mixture is determined. The fractions of the multi-component mixture are determined based on at least two measured physical properties of the mixture and knowledge of the same physical property of the individual components. The velocity of the multi component mixture is determined. The flow rate of the individual component of the fluid is determined. An electromagnetic measurement is performed. A statistical parameter related to the electromagnetic measurement is calculated and compared to an empirical derived threshold value corresponding to the value of the statistical parameter when only one of the components of the multi component mixture is present. The thickness of unwanted deposits on the pipe wall is determined and an improved flow rate determination of the individual components of the fluid is obtained.

摘要： Inert gas is produced by the combustion of hydrocarbon fuel and air in a combustion chamber. The gaseous product of the combustion is cooled in a scrubbing chamber.The amount of inert gas produced is measured, and in accordance therewith the fuel-to-air ratio of the combustion is controlled discontinuously between set time intervals.

摘要： A fluid flow metering device and a method thereof are provided. The fluid flow metering device includes a fluid flow detector, a memory, a micro controller and a power generator. The fluid flow detector is disposed in a supply tube of a fluid flow provider. When the fluid flows in the supply tube, the power generator generates a supplying power through flow of the fluid, and provides the supplying power to the fluid flow detector, the memory and the micro controller. When the fluid flow detector detects the flow of the fluid, the fluid flow detector detects the flow of the fluid outputted from the supply tube to derive a detecting value. The micro controller receives the detecting value and writes the detecting value into the memory, or the micro controller converts the detecting value into a flow value and writes the flow value into the memory.

摘要： A probe for the measurement of the total pressure or temperature of a two phase wet gas flow is also disclosed. Embodiments provide a stem, a tip on the top of the stem, a cup serving as a shield is formed in the tip, a at least one tube or thermal element positioned within the cup serving as a measuring device for the incoming wet gas flow; at least one hole which passes through at least one wall of the cup; and a pressure changing device configured to accelerate the wet gas flowing around the cup. A method and system for the measurement of the total pressure or temperature of a two phase wet gas flow is also disclosed.

摘要： A performance inspection system for an array ultrasound transducer includes: a driver for selectively applying an electric signal to all or some parts of constituent channels of the array ultrasound transducer; an acoustic power measurement unit for measuring an ultrasound acoustic power emitted from individual channels receiving the same voltage from the driver; a radiation conductance conversion unit for measuring a voltage signal applied to each channel although the driver applies different voltages to the individual channels, and converting the measured voltage into an ultrasound acoustic power acquired when the same voltage is applied to the channels; and a channel uniformity estimation unit for estimating uniformity of the acoustic power value acquired by the radiation conductance conversion unit or uniformity of acoustic power values of the individual channels measured under the same voltage.
