K-Bar 2000B Massendurchflussmesser
Produktbeschreibung
Die K-BAR 2000B nutzt die patentierte B-Series-Technologie, umGas, Geschwindigkeit und Temperatur an mehreren Stellen überdie Spanne zu messen. Mit dem schnellen Dual FD2 Metall Clad™ Sensor berechnet die K-BAR 2000B die Masse, Geschwindigkeitund Temperatur an jedem Punkt, und die Serie 155 Mass Flow-Computernutzt diese Daten, um die durchschnittliche Geschwindigkeit unddurchschnittliche Temperatur innerhalb des Prozesses zu rechnen. Esist ideal für Kanäle, welche eine weitreichendeGeschwindigkeit und Temperaturbereich haben. Temperaturbereichreicht von 260 °C bis 500 °C.
