The SITRANS FC330 digital Coriolis flow system enhances your productivity by increasing the efficiency of every liquid and gas process. The result is a cutting-edge flowmeter at the top of its class in accuracy and reliability – yet space-saving and easy to work with.

The digitally based FC330 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 FC330 simplifies your day-to-day operation with features like an easy-to-navigate graphic display, an integrated USB port and a removable SensorFlash® microSD card, which provides direct access to all data, certificates and audit trails.

The meter comes complete with 18 different preprogrammed fraction flow settings, including Brix, Plato, alcohol percentage and Baume. It can also reliably measure a variety of liquids containing up to 10% aeration due to its advanced driver circuit and high-speed signal transfer.

The FC330 flow system is available as standard with Profibus DP/PA, Modbus RS485 or 4-20 mA analog output with HART. Additional input/output functions can be configured freely for analog, pulse, frequency, relay or status. The complete system can be ordered for standard or hygienic service.

The FC330 flowmeter consists of a SITRANS FCS300 sensor and a SITRANS FCT030 transmitter.
