Turbine flowmeter for viscous liquid and using method thereof

The invention discloses a turbine flowmeter for viscous liquid and a using method thereof. The turbine flowmeter comprises a shell, a turbine transmitter, a pressure sensor, a temperature sensor and an intelligent instrument, the turbine transmitter, the pressure sensor, the temperature sensor and the intelligent instrument are arranged on the shell, the intelligent instrument comprises a flow measuring element, a storage element and a signal processing element, and the flow measuring element, the storage element and the signal processing element are respectively used for receiving flow signals of flowing viscous liquid. The instrument coefficient database is used for storing the medium type containing the viscous liquid, the impeller rotating speed, the pressure, the temperature and the instrument coefficient, and the instrument coefficient database is used for matching the medium type of the viscous liquid and the received signal with the instrument coefficient database to obtain a to-be-corrected instrumen
