Depth-integrating sampler measurements require specific
constant rate raising and lowering to get accurate data collection
sampling. Currently the best way of achieving this is using the
VTP-99 rate pacer with the correct tables and hand crank up and
down at a proper cadence which correlates to the transit rate for
a particular sampling measurement.
The new VSR-01 is designed to be used with the B-56 and E-53
sounding reels to raise and lower a sediment or water quality
sampler at a user set transit rate from .1 up to 5 fps. It has a
75 lb. capacity using 12 VDC deep cycle marine batteries designed
for a P-72, D-74 or D-95 sampler or can be used with the P-61 or
D-96 (130 lb.) with a portable AC generator. The VSR-01 is a
V-belt driven unit with variable speed DC motor and electronic
braking for accurate controlled lowering. It is user controlled in
.1 fps increments that the operator sets on a digital tachometer
control.
