Installation Guidelines

• Mounting: Install the transmitter at the top of the tank or vessel, ensuring the face of the transducer is parallel to the liquid surface.
• Clearance: Maintain a clear path between the transducer and the material surface to avoid interference from tank obstructions.
• Cabling: Ensure proper shielding of signal cables to prevent electromagnetic interference. Follow local electrical standards for 24 V DC installations.
• Calibration: Verify the sensor configuration and set the zero and span points according to the specific vessel dimensions and process requirements.
• Environmental Factors: While the transducer material is robust, ensure the installation location protects the electronics housing from direct flooding or excessive environmental exposure.
