What is Hot Wire Flow Sensors?
Hot wire flow sensors measure fluid velocity by observing the cooling effect of flow on a heated wire. A thin wire, typically platinum or tungsten, is heated to a temperature above the the ambient fluid. As fluid flows past the wire, heat is transferred away, causing the wire's temperature and thus its electrical resistance to change. An electronic circuit maintains either constant wire temperature or constant heating power, and the resulting voltage or current required to do so is directly correlated to the mass flow rate. These sensors are vital for applications like engine air intake, medical ventilators, and industrial process control due to their fast response and accuracy.
