Ultrasonic wave type level meters

YU-45 series
YU-45 series
Multi-functional ultrasonic level meter that can measure 2 channels

Non contact level meter with 2CH measurement.
Non contact level meter for medium to long distance of 0.3 to 20 m.
Easy to adjust the settings in the field. Immune to external noise and interference.

  • For liquid
  • For powder

For connections, screw-in and flange type connections are available with an angle adjustment function for powder and granulated materials.

 

Features, keys

  1. The sensor and amplifier are separated from each other. A multiple amplifier is employed that can measure two channels
    It has good cost performance due to the multiple amplifiers.
    * When 1 channel is used, two lines can be output (8 alarms and 2 current outputs).
    * Using two channels, low cost level measurement is possible.
  2. Easy to adjust settings at fields
    A large LED is used for display. The display not only shows levels, but echo wave form and trend graphs. Therefore, it allows easy adjustment locally.
  3. Various functions for measurements
    By apply correlational processing to the received ultrasonic wave signals, external noise and external ultrasonic wave effects are decreased.
    Eco graph screen and trend screen are standard. Various process setting functions on these screens allow high stability in poor measuring conditions.

*1: The nominal measuring distance is determined by the static water level used as a reflecting mirror. It may become shorter with various measuring conditions.
(Steam, condensation, waves, powder and granulated materials, etc.)
*2: The actual measuring range is determined by each measuring condition.For details, contact to our staff.
A meter with a weir meter function is also available as optional.
