Hot Wire Anemometer Details

Tips: 2 working modes of hot wire anemometer

Constant current type, also known as constant current method, that is, the current of heating the wire remains constant, the temperature of the wire will decrease after the gas takes away part of the heat. The higher the flow rate, the more the temperature will be reduced. When the temperature changes, the resistance of the hot wire and the voltage at both ends changes, so the temperature of the wire can be measured to know the size of the flow rate.

Constant temperature type, also known as the constant resistance method, changes the heating current so that the heat taken away by the gas can be replenished, and the temperature of the wire remains unchanged, such as maintaining 150 ℃, the greater the flow rate, the greater the required heating current. According to the current required to be applied, the size of the flow rate can be known. The constant temperature type of hot wire anemometer is more widely used than the constant current type.
