Function

Emptying a tank

The high level controller starts the pump …
… which regulates the level …
… to a predetermined low level.
The low level controller stops the pump.

Filling a tank

Through inflow, the level rises again …
... until the determined high level is reached …
… and the pump process begins anew.

Installation

When installing the level controllers make sure that they are suspended freely and vertically, that they do not rest on the base, that they can float without
interference from the shaft walls, pipes, fittings etc. and that they are not exposed directly to currents.

For simple mounting we can supply cable support brackets. The stainless steel support bracket is mounted on the wall. With the included M16 cable glands, one or two level controllers can be suspended freely at exactly the required height.

Electrical Connection

The level controllers are usually connected to a low voltage control circuit through a control panel. They may not operate directly on an electrical supply line, e.g. not directly on a pump motor – except Type KR1 EX and N1.

Maintenance

If correctly installed and mounted, the level controllers function is practically maintenance-free.
Depending on the medium's pollution level, the installation must be checked from time to time for dirt deposits and cleaned if necessary.
