Patent number: 5748492Abstract: The heating value of a sample gas is calculated by a microcontroller (12) from the heating value of a reference gas, and from flow ratios determined as the gas is consumed by catalytic combustion. In a preferred embodiment, chambers (5, 14) of fixed volume are charged to a predetermined pressure with a reference gas and a sample gas, respectively, and flowed to the catalyst at variable, changing flow rates as pressure decays. During the discharge cycle, a pressure transducer (13) senses the decaying pressure and this information is input to the microcontroller (12), which computes molar flow rates and which also senses the power level of combustion through a bridge circuit (24) in the catalytic apparatus (8, 10). Based on a ratio of molar flow rates and a ratio of corresponding power levels, a heating value of the sample gas is calculated by the microcontroller (12) and output to a visual display or other output device.Type: GrantFiled: February 9, 1996Date of Patent: May 5, 1998Assignee: Badger Meter, Inc.Inventors: William H.

Patent number: 5726906Abstract: A method for determining the portion of an electrochemically detectable substance in a gas sample includes the steps of introducing the gas sample into an electrochemical measuring cell 1 and generating a measurement curve i(t) by the electrochemical conversion of the substance in the measuring cell 1. The measuring curve i(t) increases from a reference line to a maximum value i.sub.max and drops back again to the reference line. Then, the maximum value i.sub.max and an area A below the measuring curve i(t) are determined. The area A is proportional to the portion of the substance in the gas sample. The method is improved in that a new measurement value is made available after a short time. This is achieved in that the maximum value i.sub.n max and the area A.sub.n of a previous measurement are compared to each other and a proportionality factor K.sub.n is determined. The proportionality factor K.sub.n is given by the ratio of the area A.sub.n to the maximum value i.sub.Type: GrantFiled: November 17, 1995Date of Patent: March 10, 1998Assignee: Dragerwerk AktiengesellschaftInventors: Hans Matthiessen, Gero Sagasser
