voltage signal.
The level meter has no setting elements, neither mechanical moving parts and so its installation is very simple. The production
of its electrodes is possible in any length in the range from 100 to 1000 mm, so that the level meter can go through entire height
of the tank. Mounting of the tank level meter is done by using 5-hole flange (SAE).

Installation and recommendations
• Level meters are installed in vertical position. Mounting of the tank level meter is done by using 5-hole flange (SAE). Distance
from the wall may be arbitrary and distance from the bottom is recommended min. 10 mm.
• Under the flange of the level, it is necessary to put in the rubber gasket resistant to petroleum products (see. Accessories).
• On the area of contact seals the tank flange is applied silicone sealant resistant to petroleum products. It is recommended
to apply sealant Gasket seal from SOUDAL or Loctite 5922
• The sensor is mounted with screws M5 5. Recommended tightening torque of 5.5 Nm for the bolts of material type 8.8 (8G).
• Measurement range sensor is adjusted by applying a magnetic pen on sensitive pads (see Instructions). Measuring the level
of other media (biodiesel, oil, etc.) must be consulted with the manufacturer (readjustment of the level meter).
• The level meter can be also used for similar applications in stationary tanks, containers, etc

Electrical connection
The level meter is designed to be connected to processing (display) units through PUR cable. Cable glands may be in design “V”
with a spiral relief in case of increased mechanical wear on the cable or in variant “H” with cable gland for protected hoses. Wiring
diagrams are shown in the following pictures.

Areas of application
Capacitive level meter CLM® is intended for continuous measurement of the level of fuel (diesel) in tanks of trucks, construction
and agricultural machinery, locomotives etc. After consultation with the manufacturer can be used for measuring and other non-conductive liquids (eg .: biodiesel, oil, etc.).
