INSTALLATION GUIDE
AMPLIFIER
Select a suitable mounting position that
is not in direct sunlight. If necessary, uti-
lize a sunshade. Observe the minimum
and maximum temperature limits (c-f).
Do not mount near sources of high
E.M.F. such as high current cables,
motor starters, or S.C.R. variable speed
drives.
BLANKING DISTANCE
The blanking distance is the distance
prior to the minimum measureable
distance from the face of the transducer.
When the transducer pulses it vibrates
the transducer face which can create &
detect unwanted echoes. As a result the
internal software creates a 'blank' zone
approximately 250-450mm (depending
on the transducers power) from the face
of the transducer.
Example 20kHz flow transducer above trapezoidal weir
Avoid mounting in high vibration areas
such as handrails and rotating plant. Use
rubber absorption mounts if mounting in
light vibration areas.
As a result the transducer face must al-
ways be mounted a minimum the blank-
ing distance away from the liquid. Ideally
the blanking distance + 50-100% of this
distance (eg, for a 20kHz with a 450mm
blanking distance we would recommend
700-1000mm between the transducer
face and the liquid).
