To enable sufficient transfer of the measured signal, note in case of installation in
plastic tanks or metal tanks with plastic lid:
►
A drill hole with a minimum diameter of 150 mm must be applied to the plastic
lid.
►
For installation of the unit, a flange plate (= launching plate R) must be used
which sufficiently covers the drill hole.
When installed in plastic tanks, there may be deterioration caused by
electromagnetic interference. Corrective measures:
• Apply a metal foil to the outside of the tank.
• Apply a shielding screen between the level sensor and other electronic
units.
