MODEL 106
The Model 106 Current Meter is a light weight,
cost effective impeller current meter, designed
for real time current measurement or short to
medium term autonomous deployments.
Titanium construction ensures durability, and the
optional temperature and pressure sensors
increase the versatility of the instrument. Ideal
for use in rivers and coastal applications, or from
small boats, the Model 106 is simple to use with
either the Windows based PC software supplied,
or an optional dedicated display unit.

The Model 106 may be used with a dedicated display unit for real
time operations. The display unit allows instrument setup and data
display.
Size:
244 x 193 x 94mm, 2kg
Protection:
IP67 (10 secs @ 0.3m)
Memory
512 Kbyte Solid State Memory. Each parameter record uses 2
bytes. As an example, this gives a duration of over 1 week with full
parameter sampling every 10 seconds, or 220 days with sampling
every 5 minutes.

Data Acquisition
The current meter works on a basic 1 second cycle, during which
the impeller counts are taken and a single compass heading
reading is made. From this, East and North velocity vectors are
calculated, which are then summed over the averaging period. The
additional parameters of temperature and pressure (if fitted) are
sampled once every sample period, and averaged over the
averaging period.
Data Recovery
Direct to PC via communications port. Maximum RS232 data rate of
19200 baud.
Switching On/Off
The meters are switched on and off through software control, either
by the DataLog™ software or by using the Model 8008 CDU.
However, it is also fitted with a sea switch mechanism, meaning
that it will not operate unless submerged. This feature means that
memory and power are conserved during periods of non-use, for
example during transportation from lab to field site. The switch can
be bypassed for setting up and equipment testing.
Software
DataLog™ Windows™ based PC software for data display,
instrument set up, data extraction and tabular and graphical data
plots.
1 x D cell. 1.5v alkaline cell gives approximately 30
days at 10 second sample rate, or 56 days at 5
minute sample rate. 3.6v Lithium cell gives
approximately 90 days at 10 second sample rate, or
180 days at 5 minute sample rate.
For external supply, 12-20v DC is required. Power
can also be taken from the Model 8008 CDU.
External:
Communications
RS232 to PC over cable lengths up to 50m. Digital Current Loop to
Model 8008 CDU, or to PC over longer cable lengths (requires
additional adaptor).
