Product details

FineTek JFR4 FMCW Radar Level Transmitter

High temperature, high pressure, and corrosive process conditions are where a lot of level sensors give up — the FineTek JFR4 FMCW radar level transmitter is built to keep working through all three, without ever touching the product it’s measuring. It installs easily, runs maintenance-free, and holds its accuracy in demanding duties that call for a sensor you can trust.

How It Works

FMCW (frequency modulated continuous wave) radar sweeps a continuous high-frequency signal from the antenna toward the product surface. The reflected signal comes back at a slightly different frequency, and that frequency difference is directly proportional to the measured distance — delivering precise, stable level readings without any contact with the medium.

Key Features

  • Non-contact measurement with no moving parts
  • Suitable for high temperature, high pressure, and corrosive service
  • High accuracy for demanding measurement duties
  • Easy installation and maintenance-free operation
  • Unaffected by product contact, coating, or density change

Applications

  • Continuous level measurement in process and storage tanks
  • Corrosive and aggressive chemical service
  • High accuracy inventory and custody measurement

Industries Served

  • Chemical and petrochemical
  • Oil and gas
  • Power generation
  • Water and wastewater treatment
