Ultrasonic wave type level meters
YU-L20 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.Washing nozzle and installation pipe are equipped as standard.

Features, keys
- 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.
- 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. - Can measure interface at two positions
The meter can measure the liquid interfaces at two positions by connecting two sensors. (2nd sensor is optional) - Washing nozzle and installation pipe are equipped as standard
A washing nozzle (for water washing) and installation pipe are equipped on the sensor as standard.
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
