METHOD FOR COMPENSATING FOR VENTURI EFFECTS ON PRESSURE SENSORS IN MOVING WATER

Apparatus for taking a water depth measurement using a probe, featuring a signal processor configured to receive signaling containing information about a water depth measurement determined from a pressure sensed by a pressure sensor contained in a probe immersed in flowing water, and also containing information about a velocity-dependent offset that is determined and depends on the velocity of theflowing water; and determining corresponding signaling containing information about a corrected water depth measurement of the flowing water by correcting the water depth measurement by the velocity-dependent offset in order to compensate for Venturi effects on the pressure sensor in the moving water. 一种用于使用探针进行水深测量的设备，该设备的特征为信号处理器，该信号处理器被配置为：接收信令，该信令包含关于从由压力传感器感测到的压力所确定的水深测量值的信息，该压力传感器被包含在被浸入流水中的探针中，并且该信令还包含关于依赖于速度的偏移的信息，该依赖于速度的偏移被确定并且取决于流水的速度；以及通过由依赖于速度的偏移而校正水深测量值，来确定对应的信令，以便补偿动水中的压力传感器上的文丘里效应，该对应的信令包含关于流水的已校正的水深测量值的信息。
