Ultrasonic Sensor - Xylem MJK Shuttle Manual

Mounting

Ultrasonic sensor

Two things are extremely important when
mounting the ultrasonic transmitter: (See
also appendix C!)
1: It should be mounted securely.
2: It should be mounted absolutely vertical.
Use a spirit level in TWO directions.
To ensure a reliable and precise level measurement it
is of vital importance that the ultrasonic sensor points
down absolutely vertical against the liquid surface.
The ultrasonic sensor should be mounted
so the ultrasonic signal has no obstructions
between sensor and surface, i.e. no pipes,
cables, grates etc.
We deliver two types of sensor brackets that can be
used in almost any installation. The bracket shown is a
standard universal mounting bracket (200220).
EN 2.10 Shuttle Manual 1712
The ultrasonic sensor is equipped with a
nut for bracket mounting. Note the recess
on the nut - it must be fitted safely in the
bracket for firm fixing to the bracket:
For the highest accuracy, the ultrasonic
sensor should be mounted as close as
possible to the highest possible level that
can occur + 35 cm (types 200570, 200640
and 200660) or 80 cm (type 200630). See
