Abstract

The invention relates to the field of gas metering, and discloses an impeller-type gas meter with temperature difference compensation, comprising an angular gas outlet, a gas meter case, an upper sealing plate, an impeller, a measuring chamber, a lower sealing plate, a temperature control device, a slider and bolts It is composed of an impeller-type gas meter with temperature difference compensation, which is characterized in that it adopts a rotor impeller-type measuring mechanism and is equipped with a temperature difference compensation device to eliminate the volume change of the gas affected by the ambient temperature. The measurement error that occurs ensures the stability of the measurement performance. The characteristics are: adopting the principle of speed measurement to realize automatic compensation of temperature difference, its structure is simple, the assembly process is good, the cost is low, and the measurement performance is stable.

Description

technical field [0001] The invention belongs to the field of gas metering, in particular to an impeller-type gas meter with temperature difference compensation. Background technique [0002] At present, household gas meters for residents in our country basically use membrane gas meters. In this type of gas meter, the principle of volume measurement is adopted. Due to the change of the volume of gas affected by the ambient temperature, the measurement error of the gas meter increases. The meter moves slowly, thus causing the metering performance of the membrane gas meter to be unstable. [0003] In addition, the measuring mechanism of the membrane gas meter has many components, the packaging process is complicated, and the manufacturing cost is relatively high. Moreover, when the membrane gas meter is used in a low temperature environment, the flexibility of the diaphragm of the measuring mechanism in the meter becomes poor, and it is easy to age and crack. Therefore, this ...
