Active Measuring Range - Xylem MJK Shuttle Manual

Appendix

Active measuring range

Shuttle 's measuring range is normally set automatically to
®
a distance corresponding to the ultrasonic sensor's distance
to zero level + 45 cm.
It may become necessary to decrease the active measuring
range so it corresponds to the highest and lowest possible
levels in the well /tank - especially if the ultrasonic sensor is
mounted above a steel grating or an opening in a well cover.
In this example, the Shuttle
decreased from 0,35 cm - 15 m to 1,45 - 3m measured
from the sensor - that is 3,00 m from the bottom to 10 cm
below the grating or cover.
Set the start distance of the measuring range measured
from the ultrasonic sensor (i.e. the highest possible level).
