Xtreem
Capacitance Water Level Logger
User Manual
The method of installation will vary with each application; following is a list of suggested methods for
some common applications.
1) Above ground small catchment with V-notch weir and stilling pond. The sensor and
Odyssey
®
Xtreem logger can be mounted in a 32mm (inside diameter 37mm) PVC or
galvanised pipe, the pipe being attached to a star picket using hose clamps. This pipe will act
as a stilling well to limit level variations caused by wind-created ripples on the water surface.
The top cap of the Xtreem logger has a suspension plug with a hole in it. This is used to tie a
stainless steel or nylon suspension line so that the Odyssey
®
sensor may be suspended from
the top of the stilling well. Note that if this line changes in length with temperature it will affect
the accuracy of the measurement.
2) Groundwater Xtreem loggers are fitted with a suspension plug on the top cover. This is used
to tie a stainless steel or nylon suspension line so that the Xtreem sensor may be suspended
from the top of the water well down to the water.
3) Stream gauging A suitable stilling well MUST be used in this application. The stilling well and
the anchoring method must also be strong enough to withstand the force of the stream flow.
32mm PVC pressure pipe ( 37mm inside diameter ) is generally adequate.
4) Tide recording in oceanographic or estuarine applications. Generally a stilling well is required
to eliminate wave action and produce a clean recording.
Teflon Sensor Cleaning
The Teflon sensor element should be carefully cleaned using either water and detergent or
methylated spirits. This will remove any deposits that have formed on the element. Care should be
taken not to bend the flexible element beyond a 100mm radius as the internal cable may become
permanently bent. The Teflon, although reasonably tough, should not be pulled over any sharp
surface as this may puncture the element and render the sensor unserviceable.
Regular sensor cleaning and calibration checking has been shown to be of vital
importance to ensure accurate measurement.
