Multi purpose, all-round, ultrasonic flowmeter for liquids in all industrial processes

OPTISONIC 3400 ultrasonic flowmeter

  • Measurement of conductive and non-conductive, low and high viscous liquids, from -200°C to +250°C media temperature
  • Accurate bi-directional measurement that starts from zero flow
  • Advanced signal converter, covering all I/O 's, HART®7, FOUNDATION ™ fieldbus

The OPTISONIC 3400 flowmeter is an unique, 3-beam, inline, ultrasonic flowmeter, designed especially for measuring homogeneous conductive and non-conductive liquids, with high accuracy and reproducibility, over a long period of time. KROHNE is a main supplier for ultrasonic in-line process flowmeters for liquids with the largest installed base / proven record in terms of robustness and measurement accuracy.

Building on vast knowledge and expertise, KROHNE now introduces the OPTISONIC 3400. This flowmeter is able to measure:

  • conductive and non-conductive liquids
  • cryogenic - and high process temperatures
  • standard and straightforward applications and applications that require high performance
  • non-viscous aqueous liquids and extreme viscous liquids
  • low pressure ratings and extreme pressure ratings

The OPTISONIC 3400 features advanced meter diagnostics

This provides extensive self-checking of internal circuits and information regarding the health of the measuring sensor, but just as importantly, vital information about the process and process conditions.

Fieldbusses are, HART®7, Foundation Fieldbus, Profibus PA and Modbus, all with NAMUR NE 107. These advanced diagnostic features makes process life comfortable, reliable and accurate over a long period of time.

The OPTISONIC 3400 features velocity of sound

Another unique feature of the OPTISONIC 3400 is the free of charge measurement of velocity of sound per acoustic path. For instance, this can supply information about pollution in the liquid, or changes in the process conditions.


  • Advanced signal converter with full range of I/O 's and communication protocols
  • Diagnostic functions according to NAMUR NE107
  • Improved user interface: optical- and push buttons
  • Completely welded construction, wear and maintenance free
  • Full bore, unobstructed sensor tube, without pressure loss and without moving parts
  • Accurate bi-directional flow measurement, with three beams to measure continuously, and starts measurement at nearly zero flow
  • Multipurpose, all-round, ultrasonic flowmeter for single phase liquids


  • Chemicals
  • Petrochemicals
  • Oil & Gas
  • Energy
  • Water (utilities)


  • Conductive and non-conductive liquids
  • Cryogenic- and high process temperature, low and extreme high pressure range
  • Expanded applicability; for standard and high performance applications
  • Measuring aqueous liquids as well as extreme viscous oils
  • High turn down ratio; e.g. transportation pipeline measurements
  • Broad pressure and temperature range (e.g. midstream oil measurements)
  • Multiple products; e.g. allocation measurements in on/off loading
  • Water utilities in all process industries; make-up water, boiler feed water, demineralized water
