Metex 3200U Ultrasonic Flow & Level Monitor - Manual (Page 17)

INSTALLATION - SENSOR LOCATION
- Tank Level/Inventory Applications
Each Ultrason Level Transmitter includes a
non-contacting ultrasonic sensor. The sensor must be
installed in a position to obtain unobstructed echoes
from the liquid or material being measured.
Mount the sensor away from pipes, ladders, or
structural members which might cause continuous
false echoes.
