This product is not suitable for Water or Sewerage applications.
The Kelco KU Series Heavy Duty Level Regulator is a compact, precision-engineered float switch designed exclusively for single-point level control in diesel and oil applications. Built with a double-moulded polypropylene housing and oil-resistant polyurethane cable, the KU Series delivers stable, repeatable switching and long service life in demanding fuel storage environments.
Its low switching differential (35mm) and all-direction tilt action make it ideal for bulk diesel tanks, oil reservoirs, and lubrication systems. The hermetically sealed float cell houses a 15A SPDT switch rated for AC or DC use, although for safety it is recommended for operation at 12–48V AC/DC in control circuits.
The KU Series is available in multiple cable lengths (1m, 4m, 6m, 10m, 20m) and can be supplied with an optional cable weight for vertical stability in deep tanks.
