Rosemount™ 2240S Multi-input Temperature Transmitter
RTG Landscape Heading
Rosemount 2240S is approved for demanding custody transfer applications that require highly accurate temperature measurements for net standard volume calculation.

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.
