9.2.3. Then enter the key settings in the Multi Beam Radar Surface Plotter software.
To do this, click settings button.
9.2.4. If this instance of the software is the master one, select "Write calculated data
to sensor". You can enable several Multi Beam Radar Surface Plotter programs si-
multaneously on the host and remote computers. Only one of them is the master one
and records the calculated parameters back to the sensor.
9.2.5. Go to "Vessel" tab. Enter vessel diameter, the total height (including the
cone). Enter the diameter of the lower cone part.
9.2.6. Go to Sensors tab. Use “+” button to add a new sensor. The sensor will be se-
lected from the list of available sensors in the server configuration. Select “Sensor
position”. Enter X, Y, Z coordinates of the sensor. Z is the vertical axis facing up-
wards. The position of X and Y axes can be seen in the visualization (to do this, se-
lect “Show Axis Arrows” in OPTIONS menu). Enter the tilt angles of the sensor
relative to three axes. Use "-" button to delete the sensor.
9.2.7. In Beams tab, configure separate measurement channels for 5-beam sensors.
Enter beam tilt angles of 5 channels of the 3D level transmitter relative to the ver-
tical axis of level transmitter. The first sensor has 0 angle, for other sensors, enter
the angles established during manufacturing for this level transmitter. The angles
for each channel are specified in the data sheet for a 3D level transmitter. Enter an-
gles as per the measuring channel numbers (“channel”).
“Min Height” field displays the automatically calculated minimum level that
corresponds to the intersection of the beam with the vessel surface. If there is inter-
ference in the tank that prevents level measurement, increase the minimum level for
this beam. In this case, when a level less than the minimum one is calculated for this
beam, this measurement will not be involved in volume measurement and product
profile formation.
9.2.8. Then click "Save" button to save the settings and proceed to setting the next
level transmitter of the system.
9.3. Ulmcfg.
9.3.1. Set the line of minimum amplitude. The minimum amplitude line excludes
false signals from the walls of a hopper and structures that fall into the beams of the
level transmitter channels from the measurement process. The minimum amplitude
line is automatically plotted in "Configuration" tab for all channels of the 3D level
transmitter at the same time. In this case, the hopper should either be empty or have
a low level of filling. When enabling this feature, specify the actual maximum fill-
ing level for the ulmcfg software.
9.3.2. Set the volume output to the current output. Select “volume” in the field
“transferred to 4-20 mA output” in “Configuration” tab.
9.3.3. Set the volumes corresponding to output currents of 4 mA and 20 mA in the
same tab.
9.4. SCADA system.
Data is transmitted to SCADA system via OPC-interface.
The following OPC-tags are available for reading in this case:
