6. Installation 6-1. Installation φ98 φ45 Blind sector Blind sector 0.5m 0.3m Fig. 5. Installation for liquid and for solid ・ If material surface enter to the blind sector, a stand pipe shall be used to ensure that material surface can not reach the blind sector of the level meter. - Page 11 6-2. Mounting direction At the application with repose angle and the mounting position near the sidewall etc, the reflection Intensity of Level Meter may weaken or the noise reflection is likely to occur. As a countermeasure, the change of mounting direction can improve it in some cases. Level Meter has a marking at the reference position of electric field direction on Adapter.
- Page 12 ・Provide shielding to minimize noise or unwanted reflections, when crossbeams, and other supports are installed within the tank. Fig. 10. Installation precaution (3) 【False reflections】 In environments where interfering signals are generated, level meter may indicate incorrect measurements results. False reflections up to a certain level of strength can be suppressed by executing the echo learning function.

Important：In most cases sets distance from level meter to unwanted reflections as echo learning distance. If there is true echo between the level meter and the masking distance, then echo learning distance shall be set as distance to true echo.
