The highly stable high-performance 2240S multipoint temperature transmitter has been certified for applications requiring trade handover, which need to measure liquid levels and temperatures very precisely to calculate net standard volume. The Rosemount 2240S can connect up to sixteen 3-wire or 4-wire temperature point elements and an integrated level sensor.
It provides the average liquid temperature based on each single point temperature element combined with the corresponding level value, for net volume calculations. Its temperature conversion accuracy is excellent, reaching ± 0.05 °C (± 0.09 °F).

Here’s a crisp breakdown of the key features of the Rosemount 2240S Multi-Input Temperature Transmitter—perfect for a banner or summary card:
