The invention relates to a non-intrusive microwave measuring device (01) for calculating the flow rate of a fluid, the device (01) comprising:-a non-intrusive microwave fluid velocity measuring device (03) comprising a patch antenna or a horn antenna, to generate a microwave signal (14) emitted towards the fluid surface (16) at a specific elevation angle alpha and to receive a reflected microwave signal (15) with Doppler shift from the fluid surface (16); -a drone (02) to which the measuring device (03) is suspended via a suspension system (04), said suspension system (04) eliminating the vibration noise generated by the drone (02); -at least one vibration sensor for cancelling the drop velocity readings; -at least one angle sensor for compensating for pitch, roll and yaw of the drone (02) affecting the fluid surface velocity measurements.

    本发明涉及一种用于计算流体的该流量的非侵入式微波测量装置(01),该装置(01)包括:‑非侵入式微波流体速度测量装置(03),该非侵入式微波流体速度测量装置包括贴片天线或喇叭天线,以产生以特定仰角α朝向流体表面(16)发射的微波信号(14)并接收来自流体表面(16)的具有多普勒频移的反射微波信号(15);‑无人机(02),测量装置(03)经由悬挂系统(04)悬挂到该无人机,所述悬挂系统(04)消除由无人机(02)产生的振动噪声;‑至少一个振动传感器,该至少一个振动传感器用于消除下落速度读数;‑至少一个角度传感器,该至少一个角度传感器用于补偿无人机(02)的影响流体表面速度测量值的俯仰、滚转和偏航。
