Installation Guidelines

• Mounting: Mount the unit in a vertical position above the medium to be measured to ensure accurate ultrasonic echo returns.
• Obstructions: Ensure the sensor face has a clear, unobstructed line-of-sight to the surface of the medium, avoiding agitators, pipes, or tank walls within the beam path.
• Environmental Conditions: While the unit is robust, avoid mounting in locations subject to extreme vacuum or excessive foam, as these can interfere with ultrasonic wave propagation.
• Wiring: Utilize shielded cabling to minimize electrical interference and ensure the 24 V DC power supply is stable and properly grounded per industrial standards.
• Maintenance: Periodically clean the transducer face to prevent buildup of material that may cause measurement drift or loss of signal.
