Abstract
La presente invención tiene por objeto un caudalímetro térmico para fluidos de inserción de bajo coste, compuesto por un cuerpo sensor que incluye un elemento calefactor y varios sensores de medida y por un cuerpo con un método de medida que combina la medida por tiempo de vuelo (TOF) y la medida de la distribución de temperatura en un elemento caliente (medidor calorimétrico), lo que le permite operar en un rango distinto al habitual en este tipo de sensores (mayor de 500 ml/min) y con un error reducido debido al método de la redundancia de medida y a la disminución del error de medida por compensación de la temperatura del fluido.
