Flow velocity and pressure integral measuring instrument using Pitot tube method

The invention provides a flow velocity and pressure integral measuring instrument using a Pitot tube method. The flow velocity and pressure integral measuring instrument includes a Pitot tube, a sampling rod sleeved inside the Pitot tube, and a housing connected to the sampling rod. An input end of the Pitot tube is provided with a downward first inlet and an upward second inlet. An output end of the Pitot tube is provided with a first outlet and a second outlet. The first outlet communicates with the first inlet, and the second outlet communicates with the second inlet. A flow velocity detection module and a pressure detection module are arranged in the housing. The flow velocity detection module includes a differential pressure transmitter. A positive pressure end of the differential pressure transmitter is connected to the first outlet. A negative pressure end of the differential pressure transmitter is connected to the second outlet. The pressure detection module is connected to the first outlet of the Pi
