    Application Examples The application examples used in this manual illustrate typical installations using SITRANS Probe LU. Because there is often a range of ways to approach an application, other configurations may also apply. In all examples, substitute your own application details. If the examples do not apply to your application, check the applicable parameter reference for the available options.

  • Page 23: Operating The Sitrans Probe Lu

    SITRANS Probe LU has two modes of operation: RUN and PROGRAM. RUN Mode SITRANS Probe LU automatically starts in RUN mode when power is applied, and detects the material level. The primary reading displays the material level (in meters) referenced from Empty (process empty level).

  • Page 24: Program Mode

    Activate PROGRAM mode at any time, to change parameter values and set operating conditions. • For local programming, use the Siemens handheld programmer. • For programming from a distance, use either a PC running SIMATIC PDM, or a HART handheld communicator.

    The transducer emits a series of ultrasonic pulses: each pulse is reflected as an echo from the material and sensed by the transducer. The echo is processed by SITRANS Probe LU, using Siemens ’ proven Sonic Intelligence techniques. Filtering is applied to help discriminate between the true echo from the material, and false echoes from acoustic and electrical noises and agitator blades in motion.

  • Page 97: Open Channel Monitoring (Ocm)

    OCM converts a level reading (head) into a flow value using a linear algorithm. SITRANS Probe LU can convert a head level measurement into a flow rate, using a thirty- two breakpoint head-versus-flow characteristic curve. This chart is usually available from the manufacturer of the v-notch weir, Parshall flume, or other open channel device.

    Failsafe mode without delay. Chemical compatibility The plastic materials used in the construction of SITRANS Probe LU (ETFE, PBT, and PVDF) are resistant to attack from most chemicals. For exposure to specific environments, check with chemical compatibility charts before installing and operating SITRANS Probe LU in your application.
