Abstract
Misuratore-regolatore ad ultrasuoni della portata di un fluido comprendente coppie di emettitori-sensori in asse ad un tubo rettilineo di misura avente una sezione trasversale uniformemente decrescente a partire dal suo ingresso che presenta un andamento anulare, radiale e simmetrico rispetto all'asse del tubo e, provvisto di una griglia a struttura anulare ed a resistenza di passaggio crescente dall'estremità esterna all'estremità interna, si raccorda al tubo con un condotto di ingresso anulare, incurvato secondo un arco di cerchio ed a sezione uniformemente decrescente, che presenta una carenatura deflettrice ad andamento sostanzialmente conico in corrispondenza dell'asse del tubo; un deflettore di flusso assiale è poi previsto all'uscita del tubo per convogliare il fluido in un condotto anulare a sezione decrescente la cui luce anulare radiale di uscita è chiudibile da un otturatore mosso da mezzi di azionamento lungo l'asse del tubo stesso.
