Abstract

The invention discloses a gas ultrasonic flowmeter based on TDC-GP30 and dual-channel and a using method thereof. The using method comprises the steps that: gating two groups of transducers respectively through an electronic switch, then the time chip emits pulses, the echo signal of the ultrasonic flow will return to the time chip and the time chip transmits the calculation result to the microcontroller MCU for storage; the time chip measures the medium temperature of the pipeline in real time, the microcontroller MCU calculates the current temperature, and performs an alarm if the temperature is abnormal or stores the temperature in a data storage chip if the temperature is normal; the microcontroller MCU performs pressure collection on the pressure sensor and calculates a pipeline pressure value, and performs an alarm if the pressure is abnormal or stores the pressure in the data storage chip if the pressure is normal; storing the accumulated flow, the gas volume, the temperature, the pressure, and related instrument parameters calculated by the microcontroller MCU. According to the gas ultrasonic flowmeter based on TDC-GP30 and dual-channel and the using method thereof, the instantaneous flow of the medium in the pipeline is measured by adopting dual-channel transducers, so that the measurement errors caused by the non-uniform distribution of the fluid in the pipeline can be greatly reduced, and the accuracy of the flow measurement can be improved.

Description

Technical field [0001] The invention relates to a gas ultrasonic flowmeter, in particular to a TDC-GP30 dual-channel gas ultrasonic flowmeter and a use method, which are used for gas flow measurement and gas quality measurement. Background technique [0002] Gas ultrasonic flowmeter is a measuring instrument used to measure gas flow rate and quality. It can be widely used in process control measurement and trade settlement measurement in natural gas mining, long-distance transmission, and trade settlement. The gas ultrasonic flowmeters currently used in the market generally use mono ultrasonic transducers, which cannot accurately reflect the flow field distribution in the pipeline, resulting in low accuracy, especially at low flow rates, the measurement accuracy cannot meet the needs of trade settlement. Summary of the invention [0003] In view of the problems in the prior art, the present invention provides a dual-channel gas ultrasonic flowmeter based on TDC-GP30 and a method o...
