• The sensor must be installed as perpendicular as possible to
the liquid surface being measured .
• Avoid installing the instrument in a location where vibration
may be present during operation .
• Mount with a clear line-of-sight to the target surface .
• If installed in a cylindrically shaped vessel, ensure that the
sensor is installed just above the lowest point in the tank . This
allows measurements to be taken as the tank approaches
empty .
• Use the mounting kit to raise the instrument above the
highest point in the tank .
• Close the unit after wiring in order to maintain ingress
protection .
