  • Page 11: Chapter 2 Transmitter Overview

    Reference Manual Transmitter overview 00809-0100-4308 February 2020 Transmitter overview Theory of operation ™ The Rosemount 3308 Series is the first true wireless level transmitter that is based on the Time Domain Reflectometry (TDR) principle. Low power nano-second-pulses are guided along a probe submerged in the process media. When a pulse reaches the surface of the material it is measuring, part of the energy is reflected back to the transmitter, and the time difference between the generated and reflected pulse is converted into a distance from which the total level or interface level is calculated (see...
  • Page 12 This peak indicates the interface level. The peak is caused by reflection from the interface between an upper product and a bottom product with a relatively high dielectric constant. This peak is identified when the measurement mode is set to Product Level and Interface Level or Interface Level with Submerged Probe. Rosemount 3308 Series...
  • Page 13 Reference Manual Transmitter overview 00809-0100-4308 February 2020 2.1.4 Probe end peak It is caused by reflection from the probe end. If the probe is grounded, the peak will be positive. If the probe end is submerged in a high dielectric media, such as water, it will not be visible.

Figure 2-6: Interface Level Measurement A.

  • Page 17: Application Examples

    Storage and buffer tanks The Rosemount 3308 Series Transmitter is ideal for storage or buffer tanks for almost any liquid, such as oil, gas condensate, water, or chemicals. Low pressure separators The Rosemount 3308 Series Transmitter can measure both level and interface level, such as for separator applications.

The transmitter measures the distance to the product surface and subtracts this value from the Tank Height to determine the level. Ensure the Tank Height is as accurate as possible, since a Tank Height error results in a corresponding level value offset error.
