Faqs:
  • What is Time-of-Flight radar level measurement?
    Time-of-Flight (ToF) radar level measurement is a non-contact method that emits microwave pulses to measure the distance to a material's surface. The round-trip time of the pulse is used to calculate the level, offering high accuracy and reliability.
  • What are the main applications of the Micropilot FMR20?
    The Micropilot FMR20 is used for continuous level measurement of liquids and simpler solids, as well as flow measurement in open channels and weirs. It is widely used in water & wastewater, mining, and general industry.
  • What are the limitations of the Micropilot FMR20?
    The device has a dead-zone near the sensor where measurements are unreliable. It also requires a clear line-of-sight and may be affected by obstructions, turbulence, or heavy dust. Accuracy drops for materials with low reflectivity.
