Intelligent floater gas meter

Abstract

The invention relates to an intelligent floater gas meter. The intelligent floater gas meter comprises a shell, a gas control value arranged in the shell, a measuring pipe and a micro-processing system, wherein the gas control value leads gas into the shell, an air outlet of the measuring pipe extends out of the shell, a pipe body of the measuring pipe is vertically arranged in the shell, a floater is arranged in the measuring pipe, and a lower end of the floater is connected with a displacement sensor used for measuring the displacement of the floater in the measuring pipe; a temperature sensor used for measuring gas temperature of the shell and a pressure sensor used for measuring pressure of the shell are arranged in the shell; the displacement sensor, the temperature sensor and the pressure sensor are each connected with the micro-processing system through a signal transformer. An integral device is composed of the micro-processing system, a floater type flow sensor, the temperature sensor, the pressure sensor and the gas control value, the integration of a gas measurement and a trade settlement system can be achieved, temperature and pressure of the gas can be monitored in real time, and automatic temperature and pressure compensation can be achieved.

Description

technical field [0001] The invention belongs to the technical field of gas equipment, and relates to a gas meter, in particular to an intelligent float gas meter. Background technique [0002] The rotameter refers to a volume flow meter that measures the flow area between the floats in the vertical conical tube as the flow changes, changing the flow area between them, also known as the rotameter. [0003] In the prior art, due to the disadvantages of large working pressure loss, no temperature and pressure compensation and control valve, the rotameter cannot be used for the trade measurement of gas end users; and the commonly used diaphragm gas meters also have many problems such as large volume and complex structure. Disadvantages: Other gas trading metering devices composed of turbines, waist wheel flowmeters and control valves have disadvantages such as high cost and delicate and easily damaged rotating parts. Therefore inventing a kind of structure is reliable, intellig...
