OPTISONIC 3400 –
Multi-purpose, all-round

The OPTISONIC 3400 is a unique 3-beam inline ultrasonic flowmeter, especially designed for the continuous measurement of homoge­neous conductive and non-conductive liquids in closed, completely filled pipeline circuits. It is able to measure actual volume and mass flow, the velocity of sound and diagnostic values of flowing liquids.

The product rings in a new era marked by multi-purpose, all-round flow sensors and signal converters with full I/O options, plus full choice of communication protocols that include advanced diagnostics features. These durable instruments are highly functional, reliable and accurate over long periods of time.

  • Measurement of conductive and non-conductive, low and high viscous liquids, from -200 to +250 °C / -328 to +482 °F medium temperature
  • Full bore unobstructed sensor tube, all-welded construction without moving parts
  • Accurate bi-directional measurement that starts at nearly zero flow
  • Advanced signal converter covers all I/Os, HART® 7, FOUNDATION™ fieldbus, PROFIBUS® PA, Modbus communication protocols and features enhanced diagnostics and status indications according to NAMUR NE 107
