Abstract

The invention relates to the field of machinery, particularly a gas flowmeter and metering method thereof. The meter can be directly maintained on the pipeline without influencing the metering. The gas flowmeter comprises a flowmeter body and a bypass unit, wherein the flowmeter body comprises a main flow channel, a main metering unit and a main storage unit; the main metering unit is detachably arranged on the main flow channel, and used for detecting total gas flow rate in the main flow channel; the main storage unit is used for storing the total gas flow rate value; the bypass unit comprises a bypass flow channel, a bypass metering unit and a bypass storage unit; the bypass flow channel is arranged outside the main flow channel, and both sides of the bypass flow channel are communicated with the main flow channel; the bypass metering unit is arranged on the bypass flow channel, and used for detecting flow rate of bypass gas in the bypass flow channel; the bypass storage unit is used for storing flow rate value of the bypass gas; the display unit is used for displaying the total gas flow rate value and/or bypass gas flow rate value and/or the difference between the total gas flow rate value and the bypass gas flow rate value; and the bypass gas is the gas which flows into the bypass flow channel from the total gas.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a gas flowmeter and a measurement method thereof. Background technique [0002] Gas metering, especially the natural gas meters used in households, basically adopts mechanical meter technology, such as membrane gas meters. When the existing gas meter fails or the gas meter is regularly tested according to the regulations, it is often necessary to remove the gas meter from the gas pipeline and return it to the factory for repair or replacement of parts, so that the gas meter needs to be interrupted or a spare gas meter is required to replace it. It is inconvenient to carry out on-site maintenance and testing. Contents of the invention [0003] The invention provides a gas flow meter and a measurement method thereof, which can maintain and correct the gas meter without affecting the measurement of the gas meter. [0004] The invention provides a gas flowmeter, comprising: [0005] A flo...
