Lidar Sensing for Liquid Level and Bulk Volume Measurement

Lidar technology for precise liquid level sensing and bulk volume measurement

The non-contact liquid level sensing market adds up to around 1B$, and includes a variety of technologies. Continuous level sensors are more sophisticated fluid sensors which can provide level monitoring by measuring liquid levels within a range, rather than at a single point, producing an analog output that correlates to the level in the vessel. Non-contact sensing technologies such as radar, ultrasound, optical, and laser fall into this category.

 

Leddar technology leverages various types of optical sources (such as LED, VSCEL, laser) and detector combinations to provide cost-effective Lidar sensors delivering accurate and reliable single- or multi-point level sensing in various applications.

 

Leddar’s Key Benefits for Liquid Level Sensing and Bulk Volume Measurement

  • Cost-effective fixed-beam optical detection
  • Narrow to wide field-of-view
  • Short- to long-range capabilities
  • Single or Multi-segment configurations
  • Reliable operation in all lighting and environmental conditions
  • Low maintenance, no moving parts, no calibration needed

Leddar is particularly suited for:

  • Constrained and narrow vessels, and vessels with obstructed field of view
  • High temperature and corrosive environments
  • Challenging environments such as oil and gas tanks
  • Low dielectric material, such as most plastic, glass, paper, powders, beans, etc.

 

Leddar technology can also be used to map the surface of bulk volume stockpiles and provide a multipoint measurement, to generate a representation of its shape and to estimate its height and volume. Volume calculations and graphical representations are typically performed by a centralized software separate from the sensors.

Bulk volume applications include coal bunkers at power plants, large domes for storing raw material, large silos storing grains, large clinkers and other large silos at cement manufacturing plants, wide stockpiles, warehouses and open bins, etc. Bulk solid volumes measurements are also widely used as part of manufacturing processes that uses bulk materials.
