Compact ultrasonic level transmitter
To reach a good and safe measurement, avoiding spurious echo
(not reflected from the surface to measure) need to take care about
the sensor sensibility volume in the sound path, no obstacles or
objects must be present into the sensibility volume (lobe), see fig.2/
D/E.
On fig.2 some suggestion:
1) Install perpendiculary at the surface, see fig.2/A
2) Don’t use with foaming products, see fig.2/B
3) Avoid installation where the product distance could be less
than 0,7m, see fig.2/C
4) No obstacles or objects must be present into the sensibility
volume, see fig.2/D/E
