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.

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 pre-programmed 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.
