ABSTRACT:
An apparatus for measuring the BTU content of a gas includes a source of combustion air, a detector and a sample loop or tube connected to a six-port switching valve. The switching valve allows accurate and repeatable quantities of the gas to be obtained and mixed with the combustion air. In a second embodiment, the apparatus includes a second switching valve to obtain samples of the gas at a second pressure and calculate the BTU content at the second pressure. By measuring the BTU content at two different pressures, a quantity related to the volumetric flow of the gas between the two pressures can also be calculated.
