Control cabinet for high levels, e.g. waste oil tank.
The units are used for high level control in e.g. waste oil tanks or low level in oil tanks and barrels.

High level:
When a level corresponding to 300 mm from full level has been reached, a warning light will come on and show "Order emptying". If this is not done when the level comes up to 150 mm from full level, a solenoid valve (not included) is activated which shuts off the supply of air. This is so that it will not be possible to overfill, which in turn can cause environmental damage, and costly clean-up measures.

Solenoid valve is available as an accessory.
