FLOWSIC300 Gas Flow Measuring Instrument

Brand: Sick AG

The FLOWSIC300 ultrasonic flowmeter features a unique combination of high quality components, large measuring range, simple installation, and low installation costs.

It can be used anywhere where custody approval is not required: For internal measurements in the natural gas grid and with process measurements in the petrochemical industry.

The FLOWSIC300 incorporates proven technology and components of the rugged custody transfer quality gas flow meters from SICK for custody transfer and combines these to produce a cost-effective flowmeter for a variety of applications.

The measuring transducer at a distance of up to 15 m away from the measuring point facilitates a high level of flexibility in installation and includes continuous self-diagnostics.

The ultrasonic measurement principle does not generate any pressure loss, has no moving parts, is resistant to pulsations and pressure regulator noise and is ideal for reliable and practically drift-free operation.
  • Reliable flow measurement for checking purposes
  • Simple installation into existing pipelines
  • Efficient solution, especially for pipe diameters over 12 inches, thanks to installation onto existing pipelines and without need for a meter body
  • Reduced acquisition costs – the sensor extraction tool can be used for multiple devices
  • Low maintenance, wear and no deterioration
  • Low operating costs thanks to automated diagnostics and condition-based maintenance
  • Suitable for installation in underground compartments via remote electronics and sensors with enclosure rating IP 68
