Draining Turbid Water
A recirculating method of sampling can be
implemented by sending the drain line back to
the beaker. Data accuracy will suffer due to
sediment settling in or releasing from the pump
cavity and bubbles being introduced from the
pump. These effects can be minimized, but the
best results will be obtained from a well mixed
single pass through source.
Download data from the instrument to your PC and
process it. See Chapter VI.
Turn off power on the TCB. You can now store the
instrument.
TO AVOID FOULING THE INTERNAL WINDOWS.
ALWAYS DRAIN ALL TURBID WATER OUT OF THE
SYSTEM BEFORE STORAGE
. A simple way to do this is
to remove the intake tube from the turbid water tank and
put it in a clean water tank. Turn on TCB power, and
select Calibrate. The pump will run full power. Pump a
few liters of clean water through. You may add a little
bleach to prevent algae growth in the water passage and
pump.
To prevent air from entering the pitot tube, cover the
pitot opening with a pinched tube.
