Level Sensing

AIRMAR Level Sensing Montage

Proven, reliable technology, Airmar’s ultrasonic transducers are used in a wide variety of level sensing applications including: water & wastewater, food & beverage and oil & gas. Unlike mechanical level indicators, ultrasonic sensors are non-contact, so the risk of sensor fouling or mechanical breakdown over time is eliminated. Our Kynar® 720 models are unmatched in chemically aggressive environments.

Not sure which transducer is suitable for your application? Here are a few common questions:

  • What is the sensing range of a transducer?
    • From 5cm to 40m, we have a solution.
  • What materials can be measured?
    • Most liquids are easy to measure but some materials, like foam can absorb sound waves, reducing the sensing range.
  • What are the environmental conditions the sensor will operate in?
    • Our sensors are designed for environmentally challenging work areas however, areas with radical convection or extreme temperature changes, (i.e. near a furnace or air nozzles) are not recommended.
