Ultra compact and compatible with chemicals. The dead zone is short, making it ideal for small tanks and near distance measurement.

Compact and ultra-compact, excellent corrosion resistance optimal ultrasonic level meter in a small tank

  • The dead zone is short, making it ideal for short range (0.06 m ~) measurement.
  • Ultra compact, compact, excellent in corrosion resistance.
    ■ Response speed is fast, and it corresponds to the movement of the small and high tank liquid up and down         quickly.
    ■ In addition to continuous output of liquid surface, contact output of 2 points (upper and lower limit) is                 possible.
    ■ It is a CE marked product.

Two types can be selected according to the measurement range.

  • YU-11 measurement range ~ 0.45M 0.06

In addition, threaded connection, offers a variety of specifications, such as flange connection.
