HL2000 [Ultrasonic Interface Level Meter]

Sedimentation state is calculated from the time it takes for ultrasonic waves to reflect at the interface and be received
Ultrasonic waves have the property of reflecting at the interface between different media.
Sedimentation state is calculated from the time it takes for ultrasonic waves to be transmitted from the sensor in the water, reflected at the interface, and received.

Since the measurement is non-contact to the sediment, it is possible to measure the interface of opaque treated water or the interface in deep tanks without lowering the sensor to the target sediment.

・A wide range of distances can be measured from 0.4 to 10 m from the sensor's transmitting surface.
・A single unit can measure two locations. (Standard equipment: 1 sensor)
・Using ultrasonic waves enables measurement without effects from transparency, chromaticity and regardless of day and night.
・The interface is measured by processing calculations based on the assumption of changes in the quality of the upper water and sediment sludge concentration, so there is no need to change the setting values or readjust them depending on the condition of the facility.
・No driving parts in the converter and sensor, which enables stable measurement over a long period of time.

・Alarm output
・4-20mA
・RS232C
*Transmission to PC is possible with optional communication software.

・Interface level control in sedimentation tanks at water treatment plants, sewage treatment plants, and industrial wastewater treatment facilities

*Please contact us when extending the sensor cable.

Dirt on the sensor surface can interfere with sludge interface measurement, so please keep the sensor surface clean at all times.
Periodic wiping or constant cleaning with the optional cleaning nozzle is recommended.
When using the cleaning nozzle, always run water (Max. 20L/min *Circulation is acceptable)
