Ultrasonic Flowmeters – Liquid

Veronics Instruments Inc. proudly represents GE Industrial Sensing’s (Formerly Panametrics) Ultrasonic Flowmeters for Liquids.

GE Panametrics’ DF868 ultrasonic liquid flowmeter

GE Panametrics’ DF868 ultrasonic liquid flowmeter is a fixed-installation meter based on our award-winning TransPort PT868 portable ultrasonic liquid flowmeter. The DF868 is available with one or two channels. Using clamp-on flow transducers, the DF868 flowmeter measures flow rate through metal, plastic or even concrete-lined pipes without penetrating the pipe wall.

  • Single-and dual-channel modes
  • Built-in 43,000-point datalogger
  • Two independent programmable graphic LCDs
  • Automatic tracking window for best accuracy when fluid conditions change
