Le débitmètre / chaleur ultrasonique à double canal est utilisé pour mesurer le temps de transmission à ultrasons grâce à une puce de conversion numérique de temps de haute précision, qui peut efficacement surmonter les problèmes de dérive zéro et une grande erreur dans la mesure de petit débit. Le débit est mesuré par la méthode de la différence de temps. Soutenir une variété de méthodes de communication; Il présente les avantages d'une précision de mesure élevée, d'un fonctionnement simple et d'un fonctionnement stable.
Interface riche, facile à utiliser et à utiliser.
