Abstract: Disclosed is a method for effective venting of a condenser of the type having an air removal section, wherein improved is reducing dissolved oxygen or other gases content in the condensate, reducing condensate and feed water side corrosion, reducing excess condenser pressure in the condenser, and/or improving the condenser heat transfer coefficient by eliminating or reducing zones that promote subcooling selected from an air bound or a stagnant zone. The method includes replacing one or more of water filled tubes within the air bound zone or the stagnant zone with one or more vent tubes in connection with a source for venting air or other gas from the air bound zone or the stagnant zone or recognizing the ineffectiveness of an ARS in the air bound zone and providing one or more vent tubes in connection with a source for venting said air bound zone or the stagnant zone.

Abstract: The inventive method for measuring the mass of the gas component and the mass of the water vapor component of a gas/water vapor source stream flowing in a conduit under reduced pressure comprises storing a correlation of relative saturation of water in said gas and the output electrical signal of a relative humidity sensor. Next, a correlation of the flow rate of the gas component of a flowing gas/water vapor reference stream and the output electrical signal of a temperature-compensated flow sensor as a function of water vapor density is stored. A correlation of maximum water vapor saturation in the gas as a function of temperature also is stored. An electrical signal of a temperature sensor in contact with said source stream then is generated. An output electrical signal of a relative humidity sensor in contact with said source stream also is generated. An output electrical signal of a temperature-compensated flow sensor in contact with said source stream further is generated.

Abstract: A system and method is described for measuring fuel consumption by combustion engines operated in a manner wherein one component of fuel is used for the process of combustion itself and another complementary component of that same fuel is employed within a recirculation path for the purpose of cooling functions, for example, the cooling of fuel injectors. A fuel combiner is incorporated within the fuel delivery system having an output at the suction side of a fuel pump. One input to this fuel combiner is recirculated fuel, while the opposite input is make-up fuel from the fuel tank. The method and system employs a fluid meter which measures the flow of make-up fuel at the input to the combiner. Return or recirculating fuel is cooled and degassed with a gas phase separator in a preferred embodiment. Additionally, a thermally based flow meter provides for enhanced accuracies with the system and method.

Abstract: An all solid state transducer and electronic system is disclosed for measuring flow through the use of a small, low temperature heater. The heater transmits an amount of heat to the flowing medium dependent on flow rate. A first temperature sensor is located near the heater and within its thermal influence. A second temperature sensor is thermally isolated from the heater. The heater and first sensor are located relative to each other such that the difference between the temperature sensors is proportional to the logarithm of the flow rate.
