Device and method for measuring the parameters of fluid flow

A sensor device for determining fluid flow parameters, the sensor comprising:

• a base unit;
• an oblong element, having a flexible link in one end, said oblong element fixed mechanically to said base unit with said flexible link and extending into fluid, said oblong element mechanically connected to a vibration sensor;
• and
• a data acquisition module inside said base unit, said data acquisition module electrically connected to said vibration sensor, wherein said data acquisition module is adapted to determine a frequency response curve of oscillation in said oblong element due to liquid flow, and to determine flow parameters from the measured frequency response curve, wherein such flow parameters include flow speed, direction of flow, type of flow, and Reynolds number.
