A gas meter is a specialized flow ... the pipe size and schedule and can be used to calculate flow. Such meters can be used to measure almost any dry gas including ...
Gas volume corrector - device for calculating, summing and determining increments of gas volume, measured by gas meter if it were operating base conditions. For this purpose, uses as input the gas volume, measured by the gas meter and other parameters such as: gas pressure and temperature. It is used for the settlement of trade wholesale gas.
The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas: = = Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K ...
The examples are here for gas flow, but the same meter types can be used on liquids as well, with similar turndown ratios. Note that meter manufacturers state their products' turndown ratios—a specific product may have a turndown ratio that varies from the list below. [citation needed] A thermal mass flow meter has a turndown ratio of 1000:1.
The standard liter per minute (SLM or SLPM) is a unit of (molar or) mass flow rate of a gas at standard conditions for temperature and pressure (STP), which is most commonly practiced in the United States, whereas European practice revolves around the normal litre per minute (NLPM). [1]
The new technology promises more accurate natural gas readings and new safety measures. But some critics say they’re not worth the cost. Spire is installing new ‘smart meters’ around KC.
Yet other definitions are in use for industrial gas, [5] where, in the US, a standard cubic foot for industrial gas use is defined at 70 °F (21.1 °C) and 14.696 psia (101.325 kPa), while in Canada, a standard cubic meter for industrial gas use is defined at 15 °C (59 °F) and 101.325 kPa (14.696 psia).
The standard unit of specific volume is cubic meters per kilogram (m 3 /kg), but other units include ft 3 /lb, ft 3 /slug, or mL/g. [ 1 ] Specific volume for an ideal gas is related to the molar gas constant ( R ) and the gas's temperature ( T ), pressure ( P ), and molar mass ( M ):
