*Specifications are subject to change without prior notice.

UL3400 is an ultrasonic flow meter for inline liquid measurement with 3 pairs of ultrasonic sensors. The 3-beam measuring method and digital signal processor (DSP) offer highly accurate, stable measurement in a broad range of applications.
The UL3400 can be used independently of changes in physical or chemical properties of liquids such as density, viscosity or electric conductivity. A wide range of sizes spanning 25 to 2000 mm are available.

Recommended Applications

  • · High accuracy: ±0.5% of reading. 3-ultrasound beam technology enables highly accurate measurement ranging from laminar to turbulent flow.
  • · The digital signal processor ensures stable measurement and minimizes the influence of bubbles and particles.
  • · No moving parts and maintenance-free. Suitable for measuring a variety of liquids including oil and solvent, as well as for replacing turbines or PD flow meters
  • · Easy installation with compact design
  • · 4 to 20 mA current output, pulse output, and status output
  • · Explosionproof types are available; TIIS approved, and ATEX
  • · Complying with: 
    Decision No. 2011/65/EU
