  • Page 6: Measuring Principle

    In this case, the level of the medium in the vessel is at the set limit. The Gammapilot FMG50 indicates the uncovered state (no medium in the radiation path) with 0% and the covered state (radiation path filled with medium) with 100%.
  • Page 7 The density unit can be selected from a menu. The density signal of the Gammapilot FMG50 can be combined with the signal of a volume flowmeter, e.g. Promag 55S, and the mass flow can be calculated from these two signals.

  • Page 8: Measuring System

    Bulk solids applications on conveyor belts and conveyor screws. The source container is positioned above the conveyor belt and the Gammapilot FMG50 below the conveyor belt. The radiation is attenuated by the medium on the conveyor belt. The intensity of the radiation received is proportional to the density of the medium.

  • Page 9: Signal Analysis

    The Gammapilot FMG50 is available with NaI (Tl) crystals or with PVT scintillators of different lengths, ensuring that it can be optimally adapted to each individual application.
  • Page 10 The measured values of up to four samples of known density can be stored in the Gammapilot FMG50 and used for the calibration of density measurements. The Gammapilot FMG50 calculates the absorption coefficient µ and the linearization curve automatically from these values. It then uses these parameters to calculate the density from the pulse rate.
  • Page 11 Concentration Concentration measurement with radiating media The Gammapilot FMG50 calculates the concentration of the medium from the intensity of the radiation that is emitted by the medium itself. A source container and radiation source are not needed for the measurement...
  • Page 12 Measured value Measurement of mass flow (liquids) The density signal determined by the Gammapilot FMG50 is transmitted to the Promag 55S. The Promag 55S measures the volume flow; the Promag can determine a mass flow in connection with the calculated density value.

  • Page 13: System Integration

    Excess radiation: In the event of excess radiation, the Gammapilot FMG50 automatically switches off the evaluation of the radiation. The device checks the radiation regularly. As soon as the Gammapilot FMG50 establishes that the radiation has normalized or no more radiation is detected, it resumes normal operation.

  • Page 14: Input

    A0039186 Input Measured variable The Gammapilot FMG50 measures the pulse rate (number of pulses per second). This rate is proportional to the intensity of radiation at the detector. The Gammapilot M calculates the measured value from this rate: • Point level (0% = "radiation path free"; 100% = "radiation path covered") •...

  • Page 15: Measuring Range

    In the case of level measurement, the measuring range typically depends on the height of the vessel. To cover the entire measuring range, a scintillator is used that is longer than the measuring range. Several Gammapilot FMG50 units can be used for measuring ranges >3 m (9.84 ft). A0037672 Gammapilot FMG50 Max.
  • Page 16 Gammapilot FMG50 A0036646 Gammapilot FMG50 Density measurement In the case of density measurement, the density measuring range is defined by the minimum and maximum density of the measured medium. A0036645 Gammapilot FMG50 Interface measurement In the case of interface measurement, the measuring range is determined by the possible position of an interface.
