Elesa+Ganter 111286 Rapid Level with Float: HFL-ER-NO Technical Guide

The Elesa+Ganter 111286 rapid level with float, identified as HFL-ER-NO, is a compact electrical level indicator used in hydraulic systems, oil tanks, and industrial reservoirs. It is designed to signal a selected liquid level through a float and reed contact arrangement, helping maintenance teams identify level changes before they affect machine performance.

Product Function and Application

The HFL-ER-NO belongs to the Elesa+Ganter HFL-E rapid level series. This product type is suitable for applications where fast level detection is needed without complex instrumentation. The HFL-ER version is mounted by means of a 1-inch Gas threaded coupler, making it practical for hydraulic tanks and similar equipment where threaded installation is preferred.

Normally Open Contact Design

The “NO” designation means normally open contact. In practice, this means the electrical circuit closes when the float reaches the configured level. This contact logic is frequently used in warning systems, control panels, and machine protection circuits where a signal is required only after the liquid reaches a defined point.

Technical Advantages

The Elesa+Ganter 111286 rapid level with float offers a strong balance between simplicity and reliability. The adjustable dipstick design allows technicians to set the required switching point by cutting the dipstick to the necessary length. This makes it easier to adapt the level indicator to different reservoir depths and oil volume requirements.

For machine builders and maintenance engineers, the main advantage is predictable level monitoring with limited installation complexity. The technopolymer construction supports industrial use, while the float system provides a direct mechanical response to liquid movement.

FAQ

What is the Elesa+Ganter 111286 HFL-ER-NO used for?

It is used to monitor the level of oil or compatible industrial fluids in tanks and reservoirs.

What does normally open mean?

Normally open means the electrical contact is open in its resting state and closes when the float reaches the set level.

How is the HFL-ER-NO installed?

The HFL-ER version is designed for installation through a 1-inch Gas threaded coupler.

Can it be adapted to different tank depths?

Yes. The dipstick can be cut to define the required level point according to the application.
