· Installed in a non-contact manner to transmit and receive vertically regarding the target fluid, the water level or depth is expressed in terms of altitude above sea level.
· Non-contact, virtually unaffected by fluids
· Excellent stability and precision by applying digital signal processing (separate for pressure)
· Measures from 0 to 15 m (30 m) over a wide range with low energy
· Almost no effect of sensor contamination and obstacles due to the selection of the orientation angle
· Provides various output signals, easy to install, and easy to calibrate (adjust) and operate
