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).
Reduce uncertainty in oil inventory and transfers:
• Receive real-time tank data for accurate net volume calculations.
• Get certified custody transfer accuracy.
• Utilize tank capacity efficiently.
• Comply with overfill prevention standards such as API 2350.
• Use SIL 2 and SIL 3 certified devices.
Simplify installation and terminal operations:
• Benefit from unique 2-in-1 technology.
• Simplify automation and expansion with Smart Wireless.
• Use gauge emulation to replace old mechanical gauges.
