A new sensor to measure fluid velocities: the Peltier anemometer

A new type of anemometer is presented for the measurement of low fluid velocities. The device operates by means of thermoelectric effects. It is non-invasive since its increase in average temperature remains lower than 15 K. The various stages in the technical development of the system are delineate...

Description
Summary:A new type of anemometer is presented for the measurement of low fluid velocities. The device operates by means of thermoelectric effects. It is non-invasive since its increase in average temperature remains lower than 15 K. The various stages in the technical development of the system are delineated. A compensating technique is described in order to provide reliable performance during temperature variations. (Abstract quotes from original text)
