UFM 800 W/C & UFM 800 W Hot Tapping Ultrasonic Flowmeter

Brand: Krohne
Request Information
UFM 800 W
Ultrasonic flowmeters with UFS 800 W sensors for measuring the volumetric flowrate in metal pipelines. The sensors are welded to the outside of the pipelines.

UFM 800 C
Ultrasonic flowmeter with UFS 800 C sensors for measuring flow velocity in open channels. The sensors can be installed or mounted from the inside or outside of the channel.

Advantages
  • No constriction of the pipe cross-section
  • No additional pressure drop
  • Electrical conductivity, pressure, density, etc. have no effect on measurements
  • Easy to install from outside or inside
  • No maintenance requirement
  • Low power consumption
  • Low operating costs
