Abstract: A fluid level transmitter combination for placement on a tank having ?2 tank apertures. A first and second flange provides a first, second and third flange aperture over the tank aperture(s). A temperature sensor over the first flange aperture senses a temperature. A first pressure sensor over the second flange aperture senses a first pressure. A second pressure sensor senses a second pressure. A processor is coupled to the output of the second pressure sensor that implements a compensated fluid level determination algorithm using the temperature, first pressure, and second pressure to generate a compensated fluid level measurement for the process fluid. A transmitter is coupled to an output of the processor.

Abstract: A fluid level transmitter combination for placement on a tank having ?2 tank apertures. At least one flange provides a first, second and third flange aperture over the tank aperture(s). A temperature sensor over the first flange aperture senses a temperature. A first pressure sensor over the second flange aperture senses a first pressure. A level transmitter extends through the third flange aperture for transmitting a pulse signal into the process fluid or at its surface and receiving a pulse echo or a second pressure sensor senses a second pressure. A processor is coupled to the level transceiver or to an output of the second pressure sensor that implements a compensated fluid level determination algorithm using the temperature, first pressure, and pulse echo or second pressure to generate a compensated fluid level measurement for the process fluid. A transmitter is coupled to an output of the processor.
