Abstract

The invention relates to the field of gas metering, and discloses an impeller type gas meter with temperature difference compensation. The impeller type gas meter comprises an angular gas outlet, a gas meter shell, an upper sealing plate, an impeller, a measuring chamber, a lower sealing plate, a temperature control device, a sliding block, a bolt, a sealing ring and the like so as to form the impeller type gas meter with temperature difference compensation. The impeller type gas meter with temperature difference compensation is characterized in that a rotor impeller type measuring mechanism is adopted, a temperature difference compensation device is arranged, and the impeller type gas meter with temperature difference compensation aims to eliminate metering errors caused by volume changesof gas due to the influence of the environment temperature and ensure the stability of metering performance. The impeller type gas meter is characterized in that automatic temperature difference compensation is realized by adopting a speed-type measurement principle, and the impeller type gas meter is simple in structure, good in assembly process, low in cost and stable in metering performance.

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 ...
