A guided microwave level transmitter utilizes time domain reflectometry (TDR) to continuously measure the level of solids or liquids. The transmitter emits a high frequency microwave pulse guided along a cable or rod. When the pulse reaches the material surface, the pulse energy is reflected back up the cable to the sensor head. Level is calculated based on the time difference between the pulse being sent and the reflected pulse received.

Strengths

  • Continuous level measurement in powders, granules, bulk solids, and liquids
  • Measuring distance up to 100 feet for solids and 75 feet for liquids
  • For light to heavy bulk solids
  • Level or interface measurement in liquids
  • 4-20 mA and Modbus RTU communications
  • Performs in solids prone to high dust
  • Suitable for vessels of most any shape or diameter, including narrow tanks or standpipes
  • Immune to condensation
  • Virtually maintenance free
  • Reliable accuracy within 0.08″
  • Hazardous location approvals
  • BinDisc simple setup and configuration
  • Compatible with BinView® software
  • Wireless communications available to reduce cost of installation

Considerations

  • Sensing rod or cable is in constant contact with material
  • Minimum dielectric constant of material must be above 1.3
  • Maximum range for solids is limited to 100 feet, and may not be suited for heavier materials due to tensile load
  • Material like large rock may damage probe and be difficult to sense
