2.1.2 Hints for probe mounting
The probe can be supplied as standard or with a screw nut or with an
ordered flange.
For applications requiring chemical compatibility the probe is available
fully enclosed in PTFE.
The use of metallic fittings or flanges is not recommended.
For exposed or sunny locations a protective hood is recommended.
Make sure that the probe is mounted perpendicular to the monitored
surface and ideally, at least 0.25 meters above it, because the probe
cannot get response in the blind zone.
The probe has a 10 inclusive conical beam angel at 3 db and must be
mounted with a clear unobstructed sight of the liquid to be measured.
But smooth vertical sidewalls weir tank will not cause false signals.
The probe must be mounted upstream of the flume or weir.
Do not over-tighten the bolts on flange.
The stilling well can be used when there is volatility in the water or
needs to improve the accuracy of level measurement. The still well
connect with the bottom of the weir or flume, and the probe measures
the level in the well.
When install to the cold area, should choose the lengthen sensor and
make the sensor extend into the container, shun frost and icing.
For Parshall flume, the probe should be installed in a position the 2/3
contraction away from the throat.
For triangular weir and rectangular weir, the probe should be installed on
the upstream side, the maximum water depths over the weir and 3~4
times away from the weir plate.
