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.

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.

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.

A gas meter with a rated maximum flow capacity of greater than 3,000 CFH (Cubic Feet per Hour)—for example, between 3,500 CFH and 7,000 CFH—is provided with 2-inch flange connectors. One or more undercuts are provided in the meter body to promote satisfactory performance in terms of, for example, differential pressures at the meter inlet and outlet.
