PIPES should be an all-metal material. Non-metallic pipes or sections are not recommended for non-contacting radar.

Plastic, PLEXIGLAS, or other non-metal MATERIALS do not shield the radar from OUTSIDE disturbances and offer minimal, if any, application benefit.

Other requirements include:

• Pipe should have a constant inside diameter
• Pipe must be smooth on the inside (smooth pipe joints are acceptable, but may reduce accuracy)
• Avoid deposits, rust, gaps and slots
• One hole above the product surface
• Minimum whole diameter is 0.25 in. (6 mm)
• Whole diameter (Ø) should not exceed 10% of the pipe diameter (D)
• Minimum distance between holes is 6 in. (150 mm) (1)
• Holes should be drilled on one side and de-burred
• Ball valve or other full valves must be completely open

Failure to follow these requirements may affect the reliability of the LEVEL measurement.
