Specially designed for use in sewage treatment plants and pump stations with liquids heavily loaded with solids, such as untreated wastewater, etc, the level controller is adjusted to the required level while freely suspended from a highly flexible cable that can be subjected to extreme loading. As the level of the liquid rises and falls, the position of the level controller changes. One level controller is required for each switching impulse. The controller is, however, fitted with a changeover contact, ie depending on the electrical connection the level controller can be used for both the filling and emptying of a container.
A micro-switch installed in a shock and fracture-proof double chamber system that is fully encapsulated and therefore completely waterproof, opens and closes the electrical circuit, causing, for example, a pump to be switched on or off, or an alarm to be triggered. Due to its practical tear shape, the stabilisation weight built into the housing and its perfectly smooth, nonporous surface, the level controller is insensitive to turbulence and, in addition, impurities cannot stick to it, and/or rags, paper and other solids slide off, and can thereby have no influence on the buoyancy of the controller. The cable inlet, which is mechanically sealed and fitted with a solid tension relief device, is also completely moulded into a separate chamber using synthetic resin, which ensures that no moisture can penetrate into the area of electrical contacts.
The electronics of the MS 1 level controller are specially suited for use in electronic circuits with switching currents between 1-100 mA and voltages between 4-30 V, for example, in areas with an explosion hazard.

Level Measurement & Control
A municipal utility in eastern Germany operates a state-of-the-art wastewater treatment plant with sustainable sludge treatment. The ultrasonic signal was being partially deflected by the wind, leading to frequent false measurements and inefficient process workflows. The problem was solved by replaced the ultrasonic level sensor with KROHNE’s OPTIWAVE 1540 non-contact radar.
