    Product, as shown below in Figure 9. The SLG 700 measures the total level of the products in the tank as well as the level of the interface (boundary) between the two liquid products in the tank. While both level measurements are available for monitoring through the HART digital interface, only one measurement can be assigned to provide the analog loop current signal to a control system.

  • Page 93: Dynamic Variables

    In addition to converting the time of flight of reflected radar pulses into a measure of distance, the SLG 700 transmitter can calculate a number of related process measurements, such as volume. In many control systems these measurements are referred to simply as process variables, however, in the terminology of the HART protocol they are referred to as Device Variables.
