THERMAL FLOW MONITORING UNIT Russian patent published in 2002 - IPC

FIELD: thermal measurement technology; thermometric systems and control and monitoring systems of environment. SUBSTANCE: device has impeller provided with blades of variable angle of attack relative to flow; this impeller is built in gas and water intake pipe; provision is also made for device converting rotational speed of impeller into thermal units of measurement. Impeller axle is connected with revolution counter. Impeller blades are made from material of reversible effect of shape memory. Geometry of impeller blade shall provide for linear dependence of impeller rotation speed on amount of heat carried by flow. Gas and water intake pipe is provided with mechanism for its orientation along flow. EFFECT: enhanced operational reliability; simplified construction. 2 cl, 1 dwg
