Kelco K Series Level Switch

Kelco K Series Level Regulating Switch available at Procon Instrument TechnologyThe Kelco K series heavy-duty level regulator is a compact three-wire float switch for highly accurate and repeatable single-point level sensing and control applications. It is ideal for use in water, sea water and most acids and alkali solutions.

It will provide a stable switching action with a very high degree of reliability. The teardrop shape of the float makes it ideal for effluent and sewerage usage, as the float cell has no shoulders or edges for solids to build on.

As the K series level regulator is not made from or contains any hazardous materials such as mercury or lead it can be reliably and safely used in potable water systems.
