  • Page 31: Radar Level Measurement

    2 Radar Level Measurement 2.1 Overview This chapter describes the theory of operation of the transmitter and discusses how measurements are affected by tank and process conditions. 2.2 Theory of Operation Guided wave radar provides level measurement based on the Time-Domain Reflectometry (TDR) principle.

  • Page 33: Tdr For Interface And Flooded Measurements

    TDR for Interface and Flooded Measurements The Time-Domain Reflectometry (TDR) principle can also be used to measure an Interface Level as well as the upper level. The position of the level interface has to be calculated with knowledge of the dielectric constant (DC ) of the upper layer.

  • Page 34: Signal Processing Configuration

    The sensor is programmed with default values for all parameters, determined by the dielectric constants of the materials being measured. Either through the advanced display or using the Honeywell DTM (SLG 700 HART option manual 34-SL-25-06) these parameters can be adjusted to match the measurement conditions. Typically, the amplitude (also referred to as gain) of the model is the only parameter that needs to be adjusted, and this is generally only required if the dielectric constant of the medium is uncertain.

  • Page 35: Amplitude Tracking

    Figure 2-4 Radar Impulse Reflection model Although the algorithms are tolerant of signal amplitude variation, a good match is important to discern the true level signal from that caused by obstacles near the probe or secondary reflections. Both the DTM and the advanced display module show the signal quality, a measure of the match between radar pulse model and acquired echo curve.

  • Page 36: Maximum Fill Rates, Latching And Timeouts

    Maximum Fill Rates, Latching and Timeouts The maximum fill rate, also referred to as Rate of Change (ROC) limits the expected level changes between two successive measurements. Software revision prior to R200 allowed a range of 4 - 20 cm/s. As of R200 this limit is increased to 90 cm/s. If a level is detected to have moved further then the ROC limit, the level status is considered bad.

  • Page 37: Signal Interferences And Background Echoes

    The user needs to ensure that the level in the tank is below these values when acquiring the background. The field background is stored in permanent memory and can be displayed using the Honeywell DTM or DD. The obstacle suppression background can be used in place of the field background and is intended to both suppress process connector reflections as well as any false echoes generated by obstacles in the tank (ladders, pipes, valves) in the vicinity of the probe.

  • Page 38: Accuracy And Measurement Range Specifications

    The most recently updated background is also stored in permanent memory and is applied after a sensor reset if dynamic background is enabled. At all times the sensor maintains a copy of the original user-acquired (static) background echo and will revert to this if the dynamic background feature is once again disabled.

    Usually, it will be the material absorption which determines the depth under which the end of probe will be visible. This can be difficult to predict as published tables might not be correct especially if there are material impurities or absorbed water present. Steam Boiler Applications Sensor revision R200 introduced a new application type: the measurement of the water level in high-pressure steam boilers.

  • Page 48: Process Condition Considerations

    2.6 Process Condition Considerations Process conditions can affect the way the surface appears to the GWR Transmitter. Turbulence Turbulence can result in the following measurement issues:  The height of the surface reflection appears smaller.  The level measurements display higher variability. In extreme cases of turbulence, the surface level measurement can be lost entirely.

  • Page 50: Blocking Distance High And Blocking Distance Low Guidance

    2.8 Blocking distance high and blocking distance low guidance The minimum blocking distances and accuracy in the transition zones may be compromised in certain applications. In these cases and in order to meet the required specifications, it is necessary to follow the guidance provided below. If the sensor performances in the transition and blocking zones are compromised due to the presence of an obstruction and if the performances cannot be improved, it is advisable to increase the configured blocking distances accordingly.
  • Page 51 It is possible for the level to rapidly leave a blocking zone and exceed the maximum fill rate. Note that the 'maximum fill rate' is the user-set maximum rate at which the level can change which will be reported before a digital flag will be set. As discussed in 2.3.3, when the maximum fill rate is exceeded, the transmitter considers the level lost and the gauge initiates the echo lost timeout counter...

    Suitable mounting position To minimize signal interference, observe the minimum distances in Table 3-15. Examples of obstacles to avoid are protruding welds, internal installations, agitators, pipes and nozzles extending into the container, heating coils, inlet streams, ladders, etc. Metallic objects are a source of bigger interferences than non-metallic objects. Turbulent applications may require the probe to be anchored to prevent it from contacting or getting too close to container walls or obstacles.

    6.2 Diagnosing SLG720 Coaxial Probe misassembly There have been a number of instances of SLG720 coaxial probes being misassembled in the field. This document is intended to help diagnose these issues; hopefully, before transmitter installation. Issues: 1. Spacer movement: if sufficient care has not been applied during assembly, the spacers, normally in place every meter, can move from the lock washers on which they are placed.
  • Page 174 End spacer should be easily visible from the end of the tube. Note that the end spacer is changing with the R200 product release, however, 20 mm 8 mm 22 mm the spacing of the central conductor with respect to the outer conductor will remain the same.
  • Page 175 Echo curve inspection (note: a DD or DTM interface is required to acquire echo curves): 1. A misplaced spacer will normally appear as a false level at the 1, 2, 3, 4, 5, or 6 m position. Misplaced spacer: The red arrow points to the position where the central conductor is likely touching the outer tube.
  • Page 176 This illustrates a properly assembled coaxial probe with an empty tank. The spacers are visible on the probe every meter but their heights are small (<1000 counts). The large reflection at 6 m is the end of the probe. This illustrates the importance of proper nut placement. The biggest effect is from a nut missing altogether SLG 700 SmartLine Level Transmitter User’s Manual Page 160...
