Abstract

Un sensor de flujo comprende una restricción del flujo dispuesta dentro de un pasaje de tal forma que un fluido que pasa a través del pasaje deber pasar a través de la restricción del flujo. El sensor de flujo también tiene un sensor de presión en corriente arriba acoplado al pasaje en un punto en corriente arriba de la restricción del flujo y configurado para medir y proporcionar una presión en corriente arriba del fluido dentro del pasaje, un sensor de presión en corriente abajo acoplado al pasaje en un punto en corriente abajo de la restricción del flujo y configurado para medir y proporcionar una presión en corriente abajo del fluido dentro del pasaje, y un sensor de temperatura acoplado al pasaje y configurado para medir y proporcionar una temperatura del fluido dentro del pasaje. El sensor de flujo también incluye un procesador del sensor de flujo acoplado a sensores de presión en corriente arriba y en corriente abajo y el sensor de temperatura y configurado para aceptar mediciones del mismo y calcular una velocidad de flujo compensada con base al menos en parte en las presiones y temperatura medidas.
