Description
technical field [0001] The invention relates to a gas flowmeter, in particular to an anti-theft turbine flowmeter whose mechanical counter adopts a metal shell and a tempered glass panel. Background technique [0002] With the development of economy and society, natural gas, as a kind of clean energy, has been widely used in more and more fields, and its consumption is also increasing year by year. Gas flow meters are commonly used metering equipment in natural gas pipeline networks. As the basis for measuring gas volume and pricing between the supply and demand sides, the accuracy of its measurement is directly related to the fairness of transactions. Gas flowmeters are divided into two types: turbine flowmeter and waist wheel flowmeter. The turbine flowmeter is mainly composed of a base meter, a gear box assembly, a mechanical counter and a volume corrector. The temperature and pressure sensors set in the base meter and the mechanical counter are set The flow detection ci...
