SITRANS FCS400 for OEM Customers

USA - SITRANS FCS400 Coriolis flow sensor

Coriolis Mass Flow Sensor

The SITRANS FCS400 is the market’s most compact Coriolis flow sensor. The small size facilitates installation and replacement, and makes it possible to fit multiple units into tight spaces. At the heart of the compact design is the CompactCurve tube shape, offering an accuracy of 0.1% of flow rate and high sensitivity for optimal measurement of even very low flows. 

From its short tube length and large bore to its cylindrical frame and hemispherical flow manifold, the SITRANS FCS400 Coriolis flow sensor was designed from the ground up with the hallmarks of superior performance and reliability: a very stable zero point, low pressure loss, and high immunity to process noise and plant vibrations.


The sensor frame isolates the metering section from plant vibration by conducting them directly through to adjacent pipeline. Careful mounting of the pipeline with regard to minimizing vibration at the meter will ensure a secure measurement environment.


In order to make a complete flow meter system, the SITRANS FCS400 flow sensor must be combined with the \SITRANS FCT030 or SITRANS FCT010 transmitter.
