Abstract

The invention relates to a mass flow sensor. The mass flow sensor comprises a first measuring pipe and a second measuring pipe, wherein the two measuring pipes are identical in structure and size and are arranged in a shell in parallel, an angle formed between the axis of a straight pipe section of each measuring pipe and the axis of a first oblique pipe section and an angle formed between the axis of the first oblique pipe section and the axis of a first port section are respectively of an obtuse angle, and an angle formed between the axis of the straight pipe section and the axis of a second oblique pipe section and an angle formed between the axis of the second oblique pipe section and the axis of a second port section are respectively of an obtuse angle. By adopting the technical scheme, when the mass flow of compressed natural gas is measured, the resistance to the compressed natural gas can be reduced; moreover, the distance can be firmly controlled, and a compressed natural gas circulation measuring pipe is enabled to have a high mechanical quality factor, good stability and high shock resistance.

Description

technical field [0001] The invention relates to the technical field of compressed natural gas, in particular to a mass flow sensor for measuring the mass flow of compressed natural gas. Background technique [0002] The utilization of natural gas as an energy source has the following advantages: first, natural gas is a high-quality green energy, and its combustion emissions are far lower than coal and oil, which can reduce environmental pollution; second, natural gas is a safe energy source, and its components do not Containing carbon monoxide, it can reduce the harm to humans and animals caused by leakage and other problems. At the same time, natural gas has a high ignition temperature and a narrow explosion limit, so it is safe; third, natural gas reserves are abundant and the cost of exploration and development is low. Based on the above advantages, natural gas is playing an increasingly important role in the development of new energy sources. At present, Compressed Natu...
