Ultrasonic noncontact measurements

Ultrasonic sensor The reflection time of a high-frequency sound pulse can be measured to give an accurate estimate of distance from an object or from a liquid level. In the latter case, an ultrasonic sensor is a noncontact alternative to a float transducer. [Pg.1903]

Rotameter Ultrasonic type Turbine flow meter Electromagnetic flow meter Good for upstream flow measurements Used in conjunction with variable inductance sensor Good for very high flow rates Can be used for both upstream and downstream flow measurements Not suited for fluids containing abrasive particles Relationship between flow rate and angular velocity is linear Least intrusive as it is noncontact type Can be used with fluids that are corrosive, contaminated, etc. The fluid has to be electrically conductive... [Pg.191]
