ANSI B109.2-2000 pdf download DIAPHRAGM-TYPE GAS DISPLACEMENT METERS (500 Cubic Feet Per Hour Capacity and Over)
1.1 ACCURACY, METER. The degree to which a meter correctly measures the volume of gas passing through it, determined by comparing the volume registered by the meter with that registered by the prover. (See Appendix D for methods of expressing meter accuracy.)
1.2 ADAPTOR PLATE, INSTRUMENT. A specially designed plate mounted between a meter and an instrument to provide for a proper drive to the instrument.
1.3 AUTOMATIC INTEGRATORS
1.3.1 Recording Type. This type of automatic integrator is equipped with corrected and uncorrected volume counters and a chart to record the time, pressure or temperature, or combinations thereof.
1.3.2 Non-Recording Type. This type of automatic integrator is equipped with corrected and uncorrected volume counters.
1.3.3 Automatic Integrating Device for Pressure. An automatic integrating device for pressure is an auxiliary device designed to automatically correct a volume-related input to ‘some predetermined base pressure condition.
1.3.4 Automatic Integrating Device for Temperature. Automatic integrating device for temperature is an auxiliary device designed to automatically correct a volume-related input to some predetermined base temperature condition in accordance with Charles’ Law.
1.3.5 Automatic Integrating Devices for Pressure and Temperature. An automatic integrator device for pressure and temperature is an auxiliary device designed to automatically correct a volume-related input to some predetermined base pressure and base temperature condition in accordance with Boyle’s Law and Charles’ Law.
1.4 AUXILIARY DEVICES. Devices used with a meter to provide an adjustment of the meter reading, to permit obtaining special information, or to transmit information to a remote location.
1.5 BADGE. A permanent plate, affixed in a conspicuous place on a meter, containing basic meter information. 1.6 BASE CONDITIONS. The standard base conditions of pressure and temperature for the volumetric measurement of natural gas, ANSVAPI 2562-1969, has established 60°F (156°C) and 14.73 psi (101.56 Wa) as the base temperature and pressure to which ail volumes are commonly referred.
1.7 BO’ITLE, CUBIC FOOT. A specially constructed and calibrated bottle, usually immersion type, complete with an immersion tank containing a light oil of low vapor pressure, with the bottle suspended over the tank by means of a suitable cord and pulley so that the bottle may be immersed in the oil between two graduations, top and bottom. The bottle is constructed so that exactly 1 cubic foot of air is displaced when the bottle is immersed between the two marks. Tbe calibration of the bottle must be traceable to the National Bureau of Standards.
