Ultrasonic wave type level meters

YU-L20 series
YU-L21 series
Ultrasonic level meter that can measure interfaces.

Non contact level meter that can detect a liquid interface in a sediment tank.
Install a sensor oscillator in water to measure.
There are no driving component and so it will provide stable measurements for a long time.
Model changed from YU-L20 type to YU-L21 type.
Measurement distance: 0.4 0.2m (short distance measurement is now possible)
Communication: RS232C RS485 (RS232C is also available)

  • For powder
  • For powder

Washing nozzles and installation pipes are available.

 

Features, keys

  1. Measures sediment interface without contact
    There is no danger of having the sensor being caught by a rake, as it is mounted separately and measures the interface without contact.
  2. There are no driving component
    There are no driving component in the converter and sensor so it will provide stable measurements for a long time.
  3. Can measure interface at two positions
    The meter can measure the liquid interfaces at two positions by connecting two sensors. (2nd sensor is optional)
  4. Washing nozzle and installation pipe (Options)
    A washing nozzle (for water washing) and installation pipe are available.
 

Usages, use examples

  • Control the interface of a sediment tank in a plant’s waste water processing facility
  • Control the interface of a sediment tank in a sewage disposal plant
  • Measure the material interface in a sludge tank
