LVR300 Series Sensor Overview Operating Principle The complete LVR300 Series Sensor is designed to be a self-contained continuous level sensor and control, requiring only a power source. A 16-bit microcontroller with a 14-bit A/D converter and a 12-bit D/A converter provides the necessary processing speed and measurement accuracy. The signal is displayed with units using a back-lit LCD graphical display and converted to a 4-20 mA signal.
LVR300 Series Programming Positions & Operation On power-up, the company logo is displayed, followed by the preset level/unit measurement. Changing the level (by float movement) will be reflected in the display. If the level is at either of the preset switch levels S1 or S2 (the upper and lower levels), the display will also be alternating between the S1 (or S2) status indication with the level reading. The Switch Active status is also indicated by a flashing LED.
LVR300 Series Quick Reference – Programming Steps HOW TO MODIFY THE SENSOR OPERATING PARAMETERS HOW TO ENTER ADDITIONAL PARAMETERS & INFORMATION Example: S1 = +18.6 Inches (or cm) + 0.0 Inch (cm) If the ring is turned right toward Position 2 (EDIT), a cursor appears while the parameter you want to modify is displayed. S1 +25.5 S1 Turning right effects a change to the next higher figure. +25. S1 Turning left moves the cursor to the next decimal position. +25.
LVR300 Continuous Level Sensor Installation Guide General Information 1. Continuous Level Sensors should be installed rigidly so the float is free to move as the liquid level changes. 2. Continuous Level Sensors should be mounted in a tank area free of severe turbulence or protected from such turbulence by appropriate and adequate slosh shields. 3.
