Speed Sensors | V5 | Introduction and Presentation
Introduction and Presentation
Read this section to get a basic knowledge of your Speed sensor.
Tip: Click Marport logo at the bottom of pages to come back to the table of contents.
Introduction
Marport’s speed sensor family includes two categories of sensors:
•The Flow sensors, that include the Trawl Speed sensor, Grid sensor and Symmetry sensor.
•The Speed Explorer
They all track pitch and roll data. Each of them has different functions and purposes.
The Grid sensor is placed on the grid of a trawl. It tells you if the grid does its job: selecting out the
unwanted catch while target species enter the codend. It monitors the angle of the grid and the
flow of water passing through it. This way, you know if the grid is twisted or blocked and you can
fix the problem before losing significant catches.
The Trawl Speed sensor can be placed on the headline. It measures water flow in two axis: the flow
along the direction of the trawl and across it. You can control if the trawl is moving at the right
speed and with the right geometry. It measures along speed up to 6 knots and cross currents speed
up to 3 knots.
The Symmetry sensor is placed on the headrope. It measures the across speed, so that you can
control if the trawl is perpendicular to the current.
Finally, the Speed Explorer has the functions of a Trawl Speed sensor and a Trawl Explorer sensor
combined. Placed on the headrope or tunnel, it measures water flow along the direction of the
trawl (up to 10 knots) and across it (up to 3 knots) and displays an echogram. This way, you can
see fish passing through the trawl and have an overview of the trawl’s opening and the effects of
the currents around it. It also track pitch & roll, depth and temperature data. Data is received more
often than with the other speed sensors.
Speed sensors are compatible with Scantrol software.

Note:
These labels tag topics or actions that are specific to Scala and/or Scala2.
Depending on the version you have, you may follow either one of these labels.
Applications
Here are some examples of data received from Grid, Trawl Speed and Speed Explorer sensors and
displayed in Scala/Scala2.
Grid sensor display
1. Control the angle of the grid (45°) / 2. Check the water flow to know if the grid is blocked

Speed Sensors | V5 | Introduction and Presentation
Speed Explorer display
1. Seabed / 2. Target strength (only for V3 version of sensors) / 3. Haddocks / 4. Trawl opening / 5.
Trawl Speed dial: displays water across and along speeds.
Trawl Speed 3D view
1. Control if the trawl opening has the correct angle. Across speed needs to be around 0.
2. Control the speed of the water along the trawl, and adjust your speed according to the currents.
