摘要： A method for determining hydrocarbon conversion factors for a flowmeter 17. A mixture of air, O.sub.2 and C.sub.x H.sub.y is burned and the partial pressure of O.sub.2 in the resulting gas is forced to equal the partial pressure of O.sub.2 in air. The flowrate of O.sub.2 flowing into the mixture is measured by flowmeter 13 and the flowrate of C.sub.x H.sub.y flowing into the mixture is measured by the flowmeter 17 conversion factor is to be determined. These measured values are used to calculate the conversion factor.

摘要： A method and device 15 is provided for a quick, accurate and on-line determination of heats of combustion of gaseous hydrocarbons. First, the amount of oxygen in the carrier stream air is sensed by oxygen sensing system 20. Second, three individual volumetric flow rates of oxygen, carrier stream air, and hydrocarbon test gas are introduced into burner 19. The hydrocarbon test gas is fed into burner 19 at a volumetric flow rate n measured by flowmeter 18. Third, the amount of oxygen in the resulting combustion products is sensed by oxygen sensing system 20. Fourth, the volumetric flow rate of oxygen is adjusted until the amount of oxygen in the combustion product equals the amount of oxygen previously sensed in the carrier stream air. This equalizing volumetric flow rate is m and is measured by flowmeter 16. The heat of combustion of the hydrocarbon test gas is then determined from the ratio m/n.

摘要： A quick-response, real-time gaseous measurement system allows for the continuous sampling of a low pressure gaseous environment. A sample of test gas from the low pressure gaseous environment is continuously extracted and pumped to a structural tee joint which is open to the atmosphere at one end to maintain the test gas at a constant pressure. The structural tee joint communicates at the other end with a heater for maintaining the test gas at a constant temperature. From the heater, the test gas is sent to a sensor which develops a voltage that is proportional to the partial pressure of the gaseous component to be measured in the test gas, a constant flow rate to test gas being provided through the heater and sensor. Since test gas pressure, temperature, and flow rate are being held constant, changes in sensor voltage are attributable only to changes in the concentration of the measured gas component.
摘要翻译：快速响应的实时气体测量系统允许连续采样低压气体环境。来自低压气体环境的试验气体的样品被连续地抽出并泵送到在一端向大气开放的结构三通接头，以将测试气体保持在恒定压力。结构三通接头在另一端与用于将测试气体保持在恒定温度的加热器连通。从加热器将测试气体送到传感器，该传感器产生一个电压，该电压与在测试气体中要测量的气体组分的分压成比例，恒定的流量以测试通过加热器和传感器提供的气体。由于测试气体压力，温度和流速保持恒定，所以传感器电压的变化仅归因于测量的气体组分的浓度变化。
