2General
This equipment is an ultrasonic current meter, emitting ultrasonic waves from
the transducer installed on the bottom of a ship to use the Doppler effects on
plankton and floating objects in seawater or on the waves reflected from the
bottom of the sea.
Using the pair-beam system in which 4 beams of ultrasonic waves are
emitted obliquely toward the bottom of the sea in 4 directions from the bow,
stern, starboard side and port side of the ship, this equipment is designed to
reduce errors caused by ship oscillation such as its pitching and rolling. By
inputting a heading signal from equipment such as a satellite compass, the
device is also designed to ignore errors caused by the ship when it turns.

3Features
(1) Clear display of both currents and deviation currents of up to 5 layers
Current values of up to 5 layers can be displayed.
The layers are displayed in different colors to clearly distinguish them.
(2) The echogram display mode
Plankton and floating objects in the sea displayed as an echogram can be
used as a guide for the measurement setting of the current meter.
(3) Continuous and stable measurement by the latest digital signal processing
technology
The cutting-edge digital signal processing technology provides continuous
and stable current values with less missing values.
(4) The measurement modes can be changed among the bottom mode, the
water mode and the GPS mode.
The modes for obtaining the current can be chosen from the ship to bottom
mode, the water mode and the GPS mode easily with the use of the supplied
remote controller (RC-20).
(5) Six different display modes if necessary
The display modes are available in 6 types; Vector Display, Character
Display, DCG-200 Display, Velocity Display, 3-D Vector Display, Echogram
Display and can be used depending on the purpose.
(6) The 3-D Vector display mode
The 3-D Vector Display mode can show the current values in three
dimensions to enable you to obtain the currents stereoscopically, which is
helpful in finding the depth when the current changes.

4Measurement Modes
4.1 Vessel Speed
The current meter measures three types of vessel speed; vessel speed to the
bottom, vessel speed to the water and GPS vessel speed. Each speed can be obtained
as shown in Fig. 1 below:

Ultrasound waves are obliquely emitted
toward the sea bottom, and these waves are
reflected by the sea bottom, and returned to
the transducer. The vessel speed to the bottom
can be obtained from this signal (reflected
signal).
②Vessel speed to the water: Vessel speed
to the seawater
This speed can be obtained from the
signal (reflected signal) of the emitted
ultrasound waves, which are reflected by
floating objects such as plankton in the sea,
and returned to the transducer.
③GPS vessel speed: Vessel speed obtained from GPS.
This is the vessel speed obtained from the satellite.

Like the ship velocity, currents are also available in
three modes.
①Bottom Mode
This measurement method is for obtaining the current
when the sea bottom can be detected. This method is
highly accurate because there are fewer causes of error
than in the other two methods.
When obtaining the current of the A-layer in Fig. 2:
A-layer current = Vessel speed to the bottom
– A-layer vessel speed to the water

KDG-300 Doppler Current Graph Instruction Manual
②Water Mode
This measurement method is for obtaining the current in the sea where the sea
bottom is too deep to detect, by using the ship velocity to the water of the base
layer.
When obtaining the B-layer current in Fig. 3:
B-layer current = Base layer vessel speed
to the water –B-layer vessel speed to the water

③GPS Mode
This measurement method is for obtaining the current value in the deep sea
where the sea bottom cannot be detected, or where the sea bottom is extremely
undulating, by using the vessel speed GPS data as the vessel speed to the bottom.
When obtaining the C-layer current in
Figure 4:
C-layer current =
GPS vessel speed – C-layer vessel speed to the water

4.3 Current Notation Method
In currents, there are those in the northwest direction and those in the southeast
direction as well.
Like currents, anything that has both a direction and magnitude (current speed in this
case) is expressed by the vector.
This device allows you to select the display mode from two choices; one is the
360-degree omni-directional display mode that displays 359 degrees clockwise with the
north direction to 0 degrees, and the other mode is the 32-point display such as NE and
SW. (Figure 5).
The velocity of the current, or current speed can be displayed in three modes (vector
display, character display and DCG200 display) in which the current is shown as the
length of the vector in a circular graph as shown in Fig. 6.
Example:
Current speed: 0.8kt

4.4 Deviation Current
When setting a net in purse seine fisheries, the net cannot be stretched
successfully if the current differs depending on the layer. In such a case, a
deviation current becomes necessary to find the changes in the current of different
layers.
The calculation method of the deviation current is described below using the
following Figs. 7-1, 7-2 and 7-3.
When one of two different currents is used as the deviation base layer as shown
Fig. 7-1, draw a line from the tip of the vector of the deviation base layer to the tip
of the vector of another current layer (Fig. 7-2).
The length of the line drawn in this way shows the magnitude (speed) of the
deviation current, and the direction of the line shows the direction of the
deviation current (Fig. 7-3).
