ABSTRACT:
The BTU content of a sample of natural gas is measured using a computer controlled microcalorimeter micro-sensor instrument employing a catalytic sensor. The instrument is portable for in field use and is able to obtain measurement accuracy of better than .+-.1%. A carrier gas, a standard reference gas and the sample gas to be measured are injected in a controlled manner through use of computer controlled solenoid valves and flow control valves, and a measurement loop injects precise gas volumes to enable a highly accurate BTU measurement by the catalytic sensor.
