Ultrasonic wave type level meters

YU-11/15 series
YU-11/15 series
Super small, corrosion resistant ultrasonic wave level meter that is ideal for very small tanks

Short non sensing range and it is ideal for short distance (0.06m at min) measurement.
Compact and excellent corrosion resistance.

  • For liquid

For connections, screw-in, flange types are available.


Features, keys

  1. Chemical proof resin is used
    The sensor is made of PFA resin that offers excellent resistance to chemicals.
  2. Can measure at short distances
    Short non sensing range and it is ideal for short distance measurement.
  3. High resolution, compact, and lightweight
    High resolution 0.1 mm allows space saving by compact sensor and main housing.

Usages, use examples

  • Detect and measure liquid levels continuously without contact
  • Measure corrosive and adhesive materials
    Ex.: Detecting levels in small tanks. Detect substances.
