  • channels
  • Eliminates problems experienced with contacting instrumentation
  • Simple set-up and operation with an integral LCD display and buttons
  • Low cost of installation and commissioning.
  • Minimal maintenance after installed
  • Process downtime minimized
  • Non-contacting measurement with no moving parts
  • Two integral signal relays (on the Rosemount 3102 only)
  • Corrosion resistant PVDF wetted material
  • Two-wire 24 V direct current loop-powered
  • Operating range up to 36 ft. (11 m)
  • Automatic temperature compensation


Advanced software features on the HART transmitters (Rosemount 3102 and 3105 only)

  • Learn routine (false echo registration)- The transmitter can learn to ignore up to four false echoes, caused by the pulse signal reflecting off obstructions.
  • Empty tank mapping- When a tank is empty, the transmitter can learn to ignore up to four false echoes, without the need for user interaction.
  • Present depth- The bottom reference can be automatically set using a known user-entered depth.
  • Set as empty- When the tank is empty, the bottom reference can be automatically reset to the measured distance.
  • Distance offset- The distance to the surface can be adjusted by a user-entered positive or negative offset value.
  • Level offset- The level can be adjusted by a user-entered positive or negative offset value.
  • Bottom blanking- The transmitter can be set to ignore an area of the tank bottom to avoid false echoes from obstructions.
