The application Basic SCADA Level represents a simple SCADA system for data acquisition and archiving from ultrasound level meters Dinel ULM-53L with the possibility of remote parametrization. The communication with level meters works via serial link RS-485 using the USB/RS485 Dinel URC-485 converter. The communication protocol MODBUS RTU is used. The application panels are accessible also via the Web interface.

Main panel The main panel displays the basic scheme of level metering. The operator can see the current level, ammount of metered substance, distance of level from meter, tank filling percentage and tank temperature.


The correct function of the level meter is signaled by a green light. There are other light signals warning the operator once the levels are outside measured range. There is a blue bargraph signaling the level position in the tank. Buttons on the side allow to open other panels.
