PRODUCT OVERVIEW

Understand the instrument

The WSR550 offers multiple range and antenna configurations for vessel and open-water measurement. A narrow beam helps direct the signal toward the target surface. Two-wire and four-wire versions, together with HART or Modbus options, allow the instrument to be matched to the installation.

KEY FEATURES

Designed for the task

  • 76–81 GHz FMCW measurement
  • Range options up to 60 m
  • Threaded or flanged installation
  • Lens and application-specific antenna options
