Abstract

ESTA BASADO EN LA MEDIDA DE LA PRESION DIFERENCIAL EXISTENTE ENTRE LA ENTRADA Y LA SALIDA DE UN ELEMENTO ESTRANGULADOR DE FLUJO, MEDIANTE UN MICROSENSOR DE PRESION INCORPORADO EN EL MISMO ELEMENTO. LA VENTAJA PRINCIPAL QUE PRESENTA EL NUEVO MEDIDOR CONSISTE EN LA INTEGRACION DE DIVERSOS ELEMENTOS EN UN UNICO DISPOSITIVO, A DIFERENCIA DE LOS MEDIDORES CONVENCIONALES QUE CONSISTEN EN UN ELEMENTO PRIMARIO QUE CREA LA DIFERENCIA DE PRESION Y UNO SECUNDARIO QUE MIDE DICHA PRESION. COMO CONSECUENCIA DE LA INTEGRACION DE LOS DISTINTOS ELEMENTOS, EL NUEVO DISPOSITIVO SE MONTA FACILMENTE EN LA TUBERIA HACIENDO INNECESARIA LA UTILIZACION DE TUBERIAS ADICIONALES Y/O VALVULAS ENTRE LOS DISPOSITIVOS PRIMARIO Y SECUNDARIO.IT IS BASED ON THE MEASUREMENT OF THE DIFFERENTIAL PRESSURE EXISTING BETWEEN THE INLET AND THE OUTLET OF A FLOW THROTTLE ELEMENT, BY MEANS OF A PRESSURE MICRO-SENSOR INCORPORATED IN THE SAME ELEMENT. THE MAIN ADVANTAGE OF THE NEW METER CONSISTS OF THE INTEGRATION OF DIFFERENT ELEMENTS IN A SINGLE DEVICE, IN DIFFERENCE FROM CONVENTIONAL METERS WHICH CONSISTE OF A PRIMARY ELEMENT THAT CREATES THE PRESSURE DIFFERENCE AND A SECONDARY ONE THAT MEASURES SAID PRESSURE. AS A CONSEQUENCE OF THE INTEGRATION OF THE DIFFERENT ELEMENTS, THE NEW DEVICE IS EASILY ASSEMBLED IN THE PIPES, MAKES THE USE OF ADDITIONAL PIPES AND/OR VALVES UNNECESSARY BETWEEN THE PRIMARY AND SECONDARY DEVICES.
