3.4 Operating Principle
Our sensor operates on radar technology, which involves sending short microwave signals towards the liquid being measured. Here's a step-by-step explanation of how it works:
· Signal Emission: The sensor emits microwave signals aimed at the surface of the liquid in the tank.
· Signal Reflection: When these microwave signals hit the liquid's surface, they bounce back towards the sensor.

PAGE 4

2024-02-20

RLI-80 NON-CONTACT RADAR LEVEL SENSOR|DATA SHEET NO. 262490 REV. C

· Time-of-Flight Principle: The sensor employs a concept called the "time-of-flight" principle. This means it measures the time it takes for the microwave signal to travel from the sensor to the liquid surface and back again.
· Distance Calculation: Knowing the speed at which microwaves travel, the sensor calculates the distance between itself and the liquid surface by dividing the total travel time by two. This division by two is because the signal had to make a round trip--down to the liquid surface and back up to the sensor.
· Liquid Level Determination: Most often, what we're interested in is the level of the liquid, not the air above it. To find the liquid level, the sensor subtracts the height of the air (non-liquid space) from the total depth of the tank. This subtraction yields the precise liquid level
3.5 Sensor Configuration
RLI-80 comes standard with integrated Bluetooth® connectivity that allows for the application parameters (Sensor Height, Fill Height) to be adjusted via standard smartphone/tablets.
4. Mounting
4.1 General Instructions
The instrument is suitable for standard and extended ambient conditions. It can be used indoors as well as outdoors.

NOTE: FOR SAFETY REASONS, THE INSTRUMENT MUST ONLY BE OPERATED WITHIN THE SPECIFIED PROCESS CONDITIONS NOTED IN THIS DOCUMENT. REVIEW THE WETTED MATERIALS OF THE SENSOR TO ENSURE THAT ALL PARTS OF THE INSTRUMENT EXPOSED TO THE PROCESS ARE CHEMICALLY COMPATIBLE. ENSURE THE PROCESS PRESSURE AND PROCESS TEMPERATURE DO NOT EXCEED THE LISTED SPECIFICATIONS.

4.2 Bracket Mounting
For open tanks you may mount the sensor using the bracket p/n 261977. The device is mounted to the bracket via the 1 ¼"-12 UNF threads at the top and the supplied jam nut. The bracket can be attached to the side of a wall or ceiling. Where possible keep the center of the sensor at least 8" away from the side of the tank wall.
4.3 Process Connection Mounting
For sealed tanks you can use the 1.5" NPT or G1.5 process connection. For sealed tanks make sure the sealant is compatible with the PVDF housing and that no sealant is placed on the sensor face. Where possible install sensor into a plastic female bung.
4.4 Process Extension Mounting
When mounting within an extended process connection, the tank end of the bung should be smooth and burrfree. The ends should also be rounded, if possible, to not get any false signals. Process extensions should also be used in medias with higher dielectric constants to ensure a stronger return signal. See the below recommended process extension diameters based on bung heights.

RLI-80 NON-CONTACT RADAR LEVEL SENSOR|DATA SHEET NO. 262490 REV. C
4.5 Sensor Location
Mount the radar sensor in a location where no other equipment or fixtures will encounter the radar beam. Obstructions within the tank or directly outside on plastic tanks (ladders, pipes) can cause false signal returns and disrupt the correct signal from the media. When possible, install the sensor at least 8" away from the tank wall. Large obstructions creating false echoes can also be weakened by installing metal baffles above them to direct the signal away from the radar sensor.

Install the sensor as perpendicular as possible to the media surface to obtain the most accurate measurement readings. The middle of the sensor face is the beginning of the measurement range.
4.6 Disconnecting the Sensor
