The present invention discloses a flow rate correction device capable of realizing wireless remote control. The device comprises a microprocessor, a pressure difference transmitter, a flow frequency detection module and a temperature sensor, wherein the pressure difference transmitter, the flow frequency detection module and the temperature sensor are all connected onto an input end of the microprocessor; an output end of the microprocessor is also connected with an output module; an A / D converter is connected in series between the pressure difference transmitter, the flow frequency detection module and the temperature sensor and the microprocessor; the microprocessor is also in bidirectional connection with a wireless transmission module; and an amplifier is also connected between the pressure difference transmitter, the flow frequency detection module and the temperature sensor and the A / D converter. The device provided by the present invention is simple in structure, actual flow of a natural gas pipeline under unified conditions can be obtained by integrating multiple reference quantities, multiple paths of different calculated quantity results can be conveniently output, and remote control and data transmission are realized.

Description

technical field [0001] The invention relates to the field of fluid conveying pipe fittings, in particular to a flow correction device capable of realizing wireless remote control. Background technique [0002] Electronic monitoring equipment is widely used in fluid delivery pipeline systems. Compared with complete mechanical metering equipment, it can facilitate remote transmission, small size, and easy equipment maintenance. It is widely used in people's daily life and industry. In production: such as urban tap water and natural gas pipeline network systems; industrial fluid transmission pipeline systems, etc. [0003] The metering of natural gas is related to the vital economic interests of every gas-using company and individual. Since natural gas is a compressible fluid, the flowmeter itself as a primary detection instrument can only detect the volume of gas under working conditions, and cannot give the volume of gas under uniform conditions, which brings great challenge...
