    Rosemount™ 2240S Multi-input Temperature Transmitter

    Rosemount

    The ultra-stable Rosemount 2240S is approved for demanding custody transfer applications, which require very accurate temperature measurements for net standard volume calculations.
    It can be used with a Rosemount 565, 566, or 765 temperature sensor. The Rosemount 2240S connects up to sixteen 3- or 4-wire temperature spot elements and an integrated water level sensor.
    It provides average liquid temperature for net volume calculation based on each individual spot temperature element in combination with the corresponding level value. It has an impressive temperature conversion accuracy of ± 0.05 °C (± 0.09 °F).
