  • What is Hot Wire Anemometer Definition Circuit Globe

    When the wire is kept in the stream of liquid in that case the heat is transferred from the wire to the fluid. The heat is directly proportional to the resistance of the wire. If heat reduces that means the resistance of wire also reduces. The Wheatstone bridge measures the variation in resistance which is equal to the flow rate of the liquid.
