TRANSMITTER MEASURING FLOW RATE AND PROCESS OF ITS MANUFACTURE Russian patent published in 1999 - IPC

FIELD: measurement of mass flow rate of liquid and gaseous media in pipe-line and open flutes. SUBSTANCE: lower part of body made of stainless steel houses frame in the form of metal rod carrying winding of heater covered with layers of insulation of material displaying high thermal conductivity. In process of manufacture of transmitter winding is applied with usage of folded wire. Layer of copper is deposited on layer of insulation covering winding and frame with winding is placed in body which lower part is filled with fusible metal. EFFECT: increased accuracy of measurement of flow rate thanks to reduced thermal resistance of transmitter. 4 cl, 1 dwg
