Four Common 天然气 Meter Types
Four Common 天然气 Meter Types
A natural gas meter is the measurement tool for gauging usage of gas based on flow through the meter. This same device plays a pertinent role in deciphering the gas bill to any structure consuming natural gas supplied by a gas utility. The meter itself is often made of steel or aluminum. Natural gas meters that were installed in colder climates prior to the 1970s were typically located inside the home in the basement or garage. Since then, the vast majority are now placed outside.
While all natural gas meters serve the same function, they may differ on the features they provide. Several different designs of meters are in common use but are dependent upon the volumetric flow rate of gas to be 测量, 预期流量范围, 以及交付压力.

The gas goes through a diaphragm (or a pair of diaphragms), which contracts and expands as gas passes through the meter, 从而转动齿轮. The gear operates another series of gears attached to an index that displays/measures gas moved. |

Uses digital technology and has no moving parts. Offers a more compact design and higher accuracy through continual self-measurement correction. |

扶轮计 |
商业和工业 |
Able to undergo higher volumes and higher pressures. Two rotors are geared together in order not to let any gas through unless they are turning. The rotation of those rotors will indicate how much gas is flowing. |

涡轮流量计 |
商业和工业 |
Measures the volume of gas flowing through the meter by determining the speed at which the gas is moving through the turbine, using a small turbine or helix. |

Natural gas comprises of almost one-fourth of all primary energy used in the United States. As a staple to everyday living, it’s important to understand how this resource is stored, 测量, 和宣传. For more information on natural gas meters, take the AYU course called ‘天然气表.
