Compact / resin integrated type. Corresponding to various liquids such as chemicals and corrosive liquids.

Small and compact, it has excellent corrosion resistance ultrasonic level meter

  • Continuous level measurement in non-contact and level detection of 2 points (upper limit, lower limit) are possible.
  • Compact, compact and excellent in corrosion resistance.
    ■ ideal for gauging under conditions such as corrosion and adhesion
    example) the waste, chemicals (acid-alkali), slurry, storage tanks, such as has been renewed by adding
            ■ echo waveform display and mask function.
■ It is a CE marked product.

The following three types are available depending on measurable distances.

  • YU-01A · ⇒ 0.15 ~ 4M
