Sensor Wand Operation and Maintenance
EXTENDING THE SENSOR WAND
The Sensor Wand is lengthened by loosening the hose clamps, pulling the telescoping sections apart
to the desired length, then re-tightening the clamps. A 5/16" nut-driver is supplied to operate the
clamps, however a screwdriver or coin may also be used.
A red painted groove is cut into each telescoping section indicating the maximum recommended
extension but no stop is provided and each section can pull out of the other if extended too far.
Carefully re-insert the section if separation occurs. NOTE: When shortening the wand it is important
to continually take up all the slack in the cable to prevent binding of the telescoping sections.
USE OF THE DEPTH PROBE
If the depth probe is desired the last (smallest) section of the wand must be extended to its
maximum length. The sensor must also be swiveled from the "stowed" position to the 90° "read"
position. Next slide the depth probe up through the 1/4" hole in the back of the sensor swivel and
screw the threaded end of the probe into the sliding collar. Raise or lower the depth probe using the
collar until the probe allows the sensor to rest at the desired depth from the stream bottom. To lock
the collar in position use the 5/16" hex head wrench and tighten the lock nut on the collar. NOTE:
The Model 2100-EXC depth probe consists of three sections plus a "foot". The top-most section
only threads onto the locking collar. Each of the other sections then thread together according to
the measuring depth required. Install the "foot" on the last section.
OPERATION WITH THE MODEL 2100 CURRENT METER
Connect the sensor to the indicator via the twist-lock connector. Swivel the sensor boom to the
desired angle (90° only when using the depth probe) and point the propeller into the stream flow.
Rotate the indicator selector switch to the MIN. Velocity position. The Model 2100 Indicator will
now display the current velocity. NOTE: This is the simplest form of operation of the current meter.
For the complete capabilities and options of the instrument see the accompanying MODEL 2100

This will reduce corrosion and prevent future difficulty in lengthening the sections. If possible allow the sections to completely air dry before collapsing and storing the wand.
