摘要： A pressure/differential pressure measuring device having a range plate with static and differential pressure sensors mounted therein. A high pressure isolation plate is mounted on one side of the range plate with a high pressure diaphragm mounted on the side of the high pressure isolation plate away from the range plate and sealed thereto forming a first fluid chamber between the inside of the high pressure diaphragm and the high pressure isolation plate side of the sensor assemblies. A low pressure isolation plate is mounted on the other side of the range plate with a low pressure diaphragm mounted on the side of the low pressure isolation plate away from the range plate and sealed thereto forming a second fluid chamber between the inside of said low pressure diaphragm and the low pressure isolation plate side of the sensor assemblies. A conduit between the first and second fluid chambers has a range diaphragm mounted to isolate the first and second chambers and means are provided to apply the high and low pressure to the outside of the high and low pressure diaphragms respectively.

摘要： Gross calorific content available from natural gas combustion determined from proportionality to molar oxygen demand in an apparatus including: provision for supplying gas and air at fixed, standard volumetric rates such that oxygen is present in excess; a combustion chamber employing swirled mixture introduction to effect complete gas burning; an oxygen sensor to detect deviation of combustion product oxygen content from an optimum setpoint value; an electrolytic hydrogen (oxygen) generator, the output of which adds to the gas and air mixture prior to combustion; and electronic control circuitry to maintain setpoint through regulation of an electrolysis current. Said current, or its control signal, also serves as a direct electronic meter of the generated species. Thus, through calibration, a measure of oxygen demand and calorific value is provided.
