Temperature & Water Interface
Product temperature is an important parameter for accurate custody transfer and inventory measurement in liquid bulk storage tanks.
The following temperature transmitters and sensors are available in a Raptor system:
- High accuracy Rosemount 2240S with 565/566 or 765 Sensors (3-or 4-wire sensor with up to 16 spot elements) for custody transfer/inventory control.
Rosemount 565 is a high quality multiple spot temperature sensor.
Rosemount 566 is the cryogenic version.
Rosemount 765 combines the temperature sensors with an integrated water level sensor
- Medium accuracy 644 Temperature Transmitter with 65 Single Point Temperature Sensor for cost-efficient measurement / operational control
 | The ultra-stable high performance 2240S Multi-input Temperature Transmitter is approved for demanding custody transfer applications, which require very accurate level and temperature measurements for net standard volume calculations. |
 | Spot elements are placed at different heights to provide a tank temperature profile and average temperature. Only fully immersed elements are used to determine product temperature. The 565/566 sensor can be integrated with a water level sensor. |
 | The water level sensor is used to determine the water content in a tank. At the bottom of an oil storage tank there is water and by measuring the water level it is possible to calculate the correct product volume in the tank. |
 | Single point temperature sensors are used in applications with lower requirements on volume measurements, or when it is not possible to use a multiple spot temperature sensor due to installation restrictions. |
