This sensor measures the height
over the bottom. That is the distance from the bottom and up to wherever
the sensor is physically located. This measurement provides you with
a valuable range of applications for bottom and pelagic trawling.
Place the height sensor behind the headrope, and
it will tell you the height of the trawl opening. This allows you
to adjust you equipment immediately if the opening is reduced, and
you will avoid loosing catch.
With a height
sensor behind the footrope you will know at once if the trawl sinks
closer to the bottom. If you use a second sensor behind the headrope,
the difference between the two height measurements will give you the
vertical height of the trawl opening.
