Intelligent flowmeter and measuring method thereof

The intelligent flowmeter comprises a pressure sensor assembly, a temperature measurement thermal resistor and a speed measurement sensor, and data measured by the pressure sensor assembly, the temperature measurement thermal resistor and the speed measurement sensor are all sent to an internal circuit board through signal lines. According to the invention, signals which are most commonly used by flow, temperature and pressure industrial instruments can be integrated and uploaded to a system through analog output or digital output, zero clearing operation can be controlled through on-site key operation or remote signal transmission, and the uploaded signals are kept unchanged in the zero clearing process, so that thermal state zero clearing of the flowmeter is realized; the flowmeter can be ensured to be in a good running state through timely zero clearing operation, and reliable running reference data can be provided in real time. 本发明公开了一种智能流量计及其测量方法，包括压力传感器组件、测温热电阻和测速传感器，压力传感器组件、测温热电阻和测速传感器所测得的数据均通过信号线上送到内部
