Gas Flow Meters FLOWSIC30

Brand: Sick AG

Ultrasonic gas flow meter FLOWSIC30 is designed for use in natural gas production applications such as coal seam gas.

The dual-path meter comes with a robust carbon steel meter body and full-titanium transducers.

The ultrasonic measurement technology has no moving parts and is virtually maintenance free.

The rugged design with integrated wires protects the meter from harsh ambient conditions while the large turn-down ratio typically covers all flow rates from a gas production well.

FLOWSIC30 is equipped with integrated diagnostics that monitor the meter status and indicate the presence of liquids in the gas stream.

With integrated pressure- and temperature measurement and volume conversion according AGA 8 it provides standard flow readings and reduces installation efforts.

Power consumption of only 65 mW and the two-wire loop powered concept make integration easy while HART® and Modbus communication provide versatility in data transfer.
  • No plate changes required - one gas flow meter for the complete well lifetime
  • No pressure loss - due to ultrasonic measurement principle
  • Optimum availability - almost wearfree operation, no liquid build up in the meter and the possibility of remote monitoring
  • Highly reliable - continuous measurement even under challenging process conditions
  • Long service life - wet gas capable ultrasonic sensors made of titanium
  • Full process control and predictable service - due to intelligent meter diagnostics
  • Low installation efforts - integration of pressure- and temperature measurement, HART®-interface and commissioning assistant
