With the SITRANS FC310 digital Coriolis flowmeter, you can fit more meters into less space and reduce skid size without compromising performance. The FC310 features an all-in-one design for streamlined installation, easy integration into your control system and optimal cost efficiency since you only pay for what you really need.

The digitally based FC310 features market-leading accuracy of 0.1% or 0.2% and density accuracy of 2 kg/m³, high immunity against process noise, low-pressure loss, an extremely stable zero point and a best-in-class 100 Hz data update rate.

The FC310 can be incorporated with minimal effort into skids, multifunctional prepared assemblies and plant operations – either new or as a drop-in replacement. The meter uses multidrop-addressable Modbus RTU RS485, a highly time-efficient communication protocol that is easy to program and diagnose. Its fully configurable byte order supports all PLC types with no additional ordering options necessary.

The complete system can be ordered for standard or hygienic service.

The FC310 flowmeter consists of a SITRANS FCS300 sensor and a SITRANS FCT010 transmitter.
