Intelligent differential type flowmeter

The utility model discloses an intelligent differential pressure flowmeter, comprising a power supply, a microprocessor, and a differential pressure transducer, a temperature sensor and a pressure sensor which are connected with the microprocessor, and characterized in that the power supply is also provided with a chip for controlling the working current and the working hours of the microprocessor and the sensors, the chip controls the microprocessor to work one time per 4s at the time of less than 1s and the current of 0.3 mA, the inoperative microprocessor is in the dormancy mode with the current of 0.01 mA, the chip controls the differential pressure transducer, the temperature sensor and the pressure sensor to work one time per 10s at the current of 1.5 mA and the time of less than 0.2s. Compared with the prior art, the intelligent differential type flowmeter has only dozens of microamperes of working current in the flow measurement, only one lithium battery is used for the intelligent differential type f
