Features

  • With Smart Echo Supervision™ technology, Rosemount Non-Contacting Radars (except for wireless models) automatically track all echoes, including those from obstructions in the vessel, and distinguish them from the real product surface echo. This ensures the true product level is reliably and accurately reported.
  • Lens antenna available for very small process fittings (3/4") and with optional bracket mount
  • All PTFE wetted parts allow for use in harsh conditions, such as corrosive medias
  • Convenient configuration and maintenance using optional Bluetooth technology
  • Schedule automatic health checks and receive report with Smart Meter Verification
  • Go back in time for troubleshooting or process insight with on-board data Historian
  • Continuously monitor measurement health with Smart Diagnostics Suite allowing for preventive maintenance and reduced downtime
  • Safe and simple proof-tests can be carried out from the control room without changing the actual level
  • ​Wireless Features​: WirelessHART® technology protocol is secure and cost-effective and delivers >99% data reliability. SmartPower™ module provides up to 10-year maintenance-free operation and field replacement without transmitter removal. Easy installation enables quick instrumentation of measurement points without the cost of wiring.
