TVMF Series Vortex Flow Meter

TVMF Series

TVMF Series vortex flow meter measures liquid, gas and steam flow using the Karman vortex street principle. It detects vortices generated by a bluff body inside the pipeline and converts the vortex frequency into flow measurement. Also, it supports integrated temperature and pressure compensation options, 4–20 mA, pulse, HART and RS485 outputs, SS304 standard body material and SS316 optional body material. As a result, it suits industrial steam, compressed air, gas, clean liquid and utility flow applications.

  • Steam, gas and liquid measurement
  • Integrated compensation options
  • 4–20 mA / HART / RS485
  • No moving parts
  • SS304 / SS316 body options
