●Mask function
Unnecessary signal can be eliminated from the received signal by manually.
Echo signal from existing structure positioned between sensor and target cause interference. Mask function removes these unnecessary echo effectively.

Three interface methods are prepared for remote operation.
  1) RS-485 (MODBUS protocol)
  2) 4 - 20 mA current output
  3) Contact points (relay output)

Level control of liquid, powder or grain in a tank
Level measurement of lakes, ponds or rivers
