⚙️ Device settings after connection

• Installation Height: The distance from the sensor to the bottom of the tank.
• Liquid Max Depth: The maximum height that the liquid can reach inside the tank.
• High alert level (Max): To activate the alert when the device is completely full.
• Low alert level (Min): To activate the alert when the liquid level is low.

🔧 Installation tips

• The sensor must be mounted perfectly vertically on the upper surface of the liquid inside the tank.
• Avoid installing the sensor in locations where:
  • Pipes inside the tank (No Pipeline)
  • Internal openings or protrusions (No protruding outlet)
  • No Floating balls
  • Interior panels or covers (No Board)
• The inner wall of the tank must be smooth (No rough inner wall) to ensure accurate reflection of the waves.
• If the mounting surface is curved, it is sufficient to fix it using screws only without strong tension.
• Make sure that the reflection area below the sensor is completely free of any obstructions.
• The ray angle is ±15°, so make sure the height and diameter are consistent as follows:
  • If the height of the tank is 4 meters, the diameter must be greater than 2 meters.
  • If the height is 3 meters, the diameter must be greater than 1.6 meters.
  • If the height is 2 meters, the diameter must be greater than 1.1 meters.
