The utility model discloses not only can detect water pressure through pressure transmitter and realize patrolling and examining automatically and the data is reported to the fire hydrant water pressure state, reduce artifical tour. Meanwhile, the water consumption of the fire hydrant can be counted through a flow meter sensor, data are reported to a data center, and real-time routing inspection of water taking and water leakage states of the fire hydrant is achieved through big data analysis. Moreover, the intelligent fire hydrant monitoring terminal with the flow meter in the embodiment can not only realize the detection of water taking and water leakage states of the fire hydrant by detecting the water pressure through the pressure transmitter 41, but also realize the detection of water taking and water leakage states of the fire hydrant by detecting the flow through the flow meter 42, thereby realizing the accurate detection of water taking and water leakage states of the fire hydrant. In addition, the intelligent fire hydrant monitoring terminal with the flow meter can realize flow detection at two positions to improve the detection precision of turbulent flow by the two flow meters 42 which are dispersedly arranged on the side wall of the detection cavity hole; it goes without saying that more flow meters 42 discretely mounted on the side walls of the detection chamber holes can be employed to achieve more localized flow detection to improve the accuracy of detection of turbulent flow.

When water flows through the flow rate detecting channel 101, the water flow drives the impeller of the impeller assembly 421 to rotate, and the water flow rate/flow rate and the rotation speed of the impeller are in a linear relationship. Meanwhile, since the impeller of the impeller assembly 421 is made of the magnet, whenever the edge of the impeller assembly 421 passes through the hall element 422, an induction signal is generated in the hall element 422, so that the water flow speed/flow in the flow detection channel 101 can be detected through the numbering condition of the induction signal, and accurate detection of micro water leakage can be realized.
