The KSMF-U Series Coriolis Mass Flowmeters are high-precision instruments based on the Coriolis effect and controlled mechanical vibration. The U-shaped dual-tube design provides high sensitivity, stability and robustness over a very wide flow range, while minimising installation constraints and impact on the process.
KSMF-U meters directly measure mass flow, density and temperature of liquids, gases and liquefied gases, with no need for upstream or downstream straight pipe runs and very low dependence on flow profile. With nominal sizes up to DN300 and flow rates up to 2,040,000 kg/h, they are particularly suited to industrial process control and commercial metering in heavy-duty applications.
