An intelligent float gas meter

Abstract

The invention relates to an intelligent float gas meter, which comprises a casing, a gas control valve, a measuring tube and a micro-processing system arranged in the casing; The tube body is vertically arranged in the casing, and a float is also arranged in the measuring tube, and the lower end of the float is connected with a displacement sensor for measuring the displacement of the float in the measuring tube; inside the casing, there are also temperature sensors for measuring the gas temperature and pressure in the casing respectively. Sensors and pressure sensors; displacement sensors, temperature sensors and pressure sensors are respectively connected with the micro-processing system through signal transmitters. The invention adopts a microprocessor system, a float type flow sensor, a temperature sensor, a pressure sensor, a gas control valve and other components to form an electromechanical integration device, which can realize the integration of gas metering and trade settlement systems, and can monitor gas temperature in real time, Pressure, can realize automatic temperature and pressure compensation.

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...
