Can Htg (hydrostatic Tank Gauging) Be Achieved Using A Single Fieldbus Instrument? If So, How? |

Answer» It should be POSSIBLE. Multivariable transmitters are well-supported by the IEC and FF PROTOCOLS. A fieldbus HTG instrument might connect directly to multiple sensors (pressure, temperature) or might PERHAPS USE a local MULTIDROP HART bus to connect to standard HART transmitters. (These could also be powered from the fieldbus, through an embedded dc-to-dc converter in the HTG device.) It should be possible.
