Part Number Nomenclature

Sensor Label
The sensor label will have the general specifications of the sensor, including but not limited to the input voltage, the output, FCC, IC information, serial number (s/n), part number (p/n), material, and approval logos. The s/n is important as it is needed to connect the sensor to the Bluetooth® App

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.
• 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.

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.

Mounting

• 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.

• 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.

• 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.

• 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. D

BUNG DIAMETER

| H

BUNG HEIGHT DIAMETER

---|---
1.5” (40 mm)| ≤ 5.9” (150 mm)
2” (50 mm)| ≤ 7.9” (200 mm)
3” (80 mm)| ≤ 11.8” (300 mm)
4” (100 mm)| ≤ 15.8” (400 mm)
5” (150 mm)| ≤ 23.6” (600 mm)

• 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.

• Disconnecting the Sensor
  WARNING: PRIOR TO DISMOUNTING, PLEASE BE AWARE OF ALL DANGEROUS PROCESS CONDITIONS NOT LIMITED TO PRESSURIZED TANK OR VESSEL, HIGH TEMPERATURES, CORROSIVE OR TOXIC MEDIA AND VAPORS. FOLLOW THE DIRECTIONS OF MOUNTING AND ELECTRICAL CONNECTION IN REVERSE ORDER.
  NOTE: SENSOR DISCONNECTION AND UNINSTALLATION SHOULD ONLY BE PERFORMED BY TRAINED PERSONNEL FAMILIAR WITH THE SENSOR’S SPECIFICATIONS AND SAFETY REQUIREMENTS. IF YOU ENCOUNTER ANY DIFFICULTIES OR UNCERTAINTIES DURING THESE PROCEDURES, SEEK ASSISTANCE FROM QUALIFIED TECHNICIANS OR OUR TECHNICAL SUPPORT TEAM.

  • Safety First: Prioritize safety by wearing appropriate personal protective equipment (PPE), including, but not limited to, gloves and eye protection.
  • Power Down: Before attempting any disconnection, power down the sensor and any associated equipment to avoid electrical hazards.
  • Turn Off Power Source: Ensure that the power source supplying the sensor is switched off and disconnected.
  • Unplug Cables: Carefully disconnect any cables or connections linked to the sensor. Exercise caution to avoid damaging connectors or cables during this process.
  • Secure the Sensor: If the sensor is mounted, make sure it is securely held in place to prevent accidental drops or movement during the disconnection.
  • Unfasten any Mounting Hardware: If required, remove any fasteners or components securing the sensor to its mount. Exercise care to avoid damaging the sensor or any surrounding equipment.
  • Assess Accessibility: Once the mounting hardware is loosened, assess whether any additional components or obstacles hinder the sensor’s removal. If necessary, temporarily relocate or adjust surrounding equipment to facilitate the dismounting process.
  • Lift and Remove: With the sensor now detached from its mount, lift it gently from the mounting location. Use caution to prevent any sudden movements or shocks during removal.
  • Inspect for Damage: After removal, inspect the sensor for any visible damage or anomalies. Make note of any issues that may require maintenance or replacement before reinstalling.
  • Store Securely: After removal, store the sensor in a clean, dry, and safe location. Ensure it is protected from potential damage during storage.

Operating Restrictions
For operation outside of closed metal vessels under the usage restriction complying with 15.256, this device must be installed and maintained to ensure a vertically downward orientation of the transmit antenna’s main beam. This device may only operate at fixed locations and may not operate while being moved, or while inside a moving container. Hand-held applications are prohibited.

Maintenance

Basic Maintenance

• Routine Maintenance:
  Under typical operating conditions, IP68 radar sensors are designed to require minimal maintenance. Their robust construction is engineered to withstand harsh environments and resist dust and temporary immersion in water.

• Monitoring for Buildup:
  Certain applications may lead to the accumulation of debris or substances on the sensor face over time. Such buildup can potentially impact measurement accuracy. Regular visual inspections can help identify when cleaning is needed.

• Cleaning Procedures:
  When it becomes necessary to clean the sensor face, it is crucial to use appropriate cleaning methods and materials that align with the sensor’s IP68 rating. Here’s how to do it effectively:

  • Select Compatible Cleaning Media: Choose cleaning media that are compatible with the sensor’s housing and seal materials. This ensures that the cleaning process does not harm or degrade any components.
  • Follow IP Rating Standards: To maintain the IP68 rating, adhere to cleaning methods and procedures suitable for devices with this level of protection against dust and temporary immersion. Avoid using excessive water pressure or aggressive cleaning agents that may compromise the sealing integrity.
