®UL3400C is a converter-integrated 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 UL3400C 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.
※Specifications are subject to change without prior notice.
