Do not mount transducers incorporating temperature
compensation in direct sunlight.
Do not over-tighten the bolts on flange construction trans-
ducers.
Flange transducers are not pressure rated and are suit-
able only for atmospheric pressure.
CENELEC approved transducers must be mounted and
wired in accordance with the appropriate National
Standards concerning installation in hazardous environ-
ments.
For differential applications mount both transducers at the
same height above the zero datum point.
For open channel flow applications the transducer must
be mounted upstream of the flume or weir as detailed in
BS3680 (usually 3 or 4 times maximum head).
