Propeller type current meters similar to the purely mechanical ekman current meter but now with electronic data acquisition can be traversed over the area of the penstock and velocities averaged to calculate total flow.
Hemodynamics or haemodynamics are the dynamics of blood flow the circulatory system is controlled by homeostatic mechanisms just as hydraulic circuits are controlled by control systems the haemodynamic response continuously monitors and adjusts to conditions in the body and its environment.

Flow through a large penstock such as used at a hydroelectric power plant can be measured by averaging the flow velocity over the entire area.
Using ultrasonic transducers the flow meter can measure the average velocity along the path of an emitted beam of ultrasound by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow.
