1 The instrument is used for the accurate determination of the current velocity in water ways channels rivers and the sea The meter can also be applied in polluted water currents The measurements are executed with the propeller mounted on the rods or connected to a cable The current velocity meter has a measuring range of 0025 to 10 msec Benefits of Current meter Universal current meter with highest accuracy Propeller covers most velocities Extremely low friction assures high accuracy even in slow running water 2 Hot Wire Anemometer Definition The Hot Wire Anemometer is a device used for measuring the velocity and direction of the fluid This can be done by measuring the heat loss of the wire which is placed in the fluid stream The wire is heated by electrical current The hot wire when placed in the stream of the fluid in that case the heat is transferred from wire to fluid and hence the temperature of wire reduces The resistance of wire measures the flow rate of the fluid The hot wire anemometer is used as a research tool in fluid mechanics It works on the principle of transfer of heat from high temperature to low temperature 3 The use of the multihole pressure probes has become See Answer
