A vortex flowmeter with temperature and pressure compensation

A high intelligent and integrating temperature and pressure compensating vortex street flow gauge is provided. When measuring gas and steam with the vortex street flow gauge, the outer coordination of a pressure and temperature transmitter is not needed, and the structure technique is simple. The utility model comprises a casing, an integrating instrument and a vortex generator, wherein the vortex generator is arranged in the casing, the casing and the integrating instrument are connected through a connecting rod, the connecting rod is arranged with a flow sensor, one end of which is connected with the integrating instrument, and a flow probe of the flow sensor is inserted in the casing and the back of the vortex generator. The utility model further comprises a temperature and pressure inversion device, which comprises a chip, a power supplying circuit, a temperature sampling circuit, a pressure sampling circuit, an enlarging and shaping circuit, a keyboard circuit and a LCD displaying circuit. Through the inner arrangement of a temperature and pressure compensating formula of flow gas, a saturated steam temperature-density meter and a superheated steam temperature pressure compensating formula on the temperature-pressure inversion device, the gas is conversed into scalar flow, the steam is conversed into mass flow and sent to display in the LCD.
