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.
