The SITRANS FCS300 is one of the most compact Coriolis flow sensors on the market. Its small size simplifies installation and replacement, and also allows you to optimize your plant layout by fitting multiple units into tight spaces.

The robust frame and housing of the FCS300 guarantee superior resistance to external vibrations, creating an ideal measurement environment with no twisting. The sensor’s tube features a short length and large diameter, minimizing pressure loss and allowing for a significantly higher mass flow rate through the meter. You benefit from a high turndown ratio of greater than 100:1 along with added flexibility in application sizing and configuration.

In order to make a complete flowmeter system, the SITRANS FCS300 sensor must be combined with the SITRANS FCT030 or SITRANS FCT010 transmitter.
