The KSMF-T Series Coriolis Mass Flowmeters are small-bore Coriolis meters with a triangular measuring-tube geometry, designed for high-precision mass flow and density measurement at low to medium flow rates. Based on the Coriolis effect and controlled mechanical vibration, KSMFT directly measures mass flow, density and process temperature for liquids, gases and liquefied gases. The triangular tube arrangement improves mechanical stability and vibration resistance, helping to maintain signal quality and accuracy even under fluctuating process conditions or external vibration.
With nominal diameters from DN3 to DN15 and flow rates up to 4,500 kg/h, KSMFT is particularly suited to dosing, injection and small-line process measurement in oil & gas, petrochemical, chemical, pulp & paper and new-energy applications.
