Installation Guidelines

• Mounting: Ensure the controller is mounted in an accessible location with adequate clearance for the local display and cable routing.
• Cable Inlets: The unit features three cable inlets; ensure proper cable glands are used to maintain the environmental integrity of the enclosure.
• Grounding: Connect the controller to a solid earth ground to ensure electrical safety and minimize electromagnetic interference.
• Transducer Placement: Ensure the ultrasonic transducer is mounted perpendicular to the surface being measured to maintain signal reflection accuracy.
• Temperature Sensor: Utilize the external temperature sensor input to provide automatic compensation for sound velocity changes due to temperature shifts.

Compliance and Certifications

• CE, FM, CSA US/C, UL, RCM, EAC, KCC (General Purpose)
