Elesa+Ganter 111281 HFL-EF-NO Rapid Level with Float
The Elesa+Ganter 111281 HFL-EF-NO rapid level with float is a practical level monitoring component for industrial tanks, hydraulic reservoirs, coolant systems, and fluid storage units. It is designed to show a predefined minimum or maximum level according to the needs of the application.
Technical Design
This HFL-EF-NO model uses flange mounting and has a 500 mm dipstick length with an approximate weight of 135 g. The body is manufactured from grey polyamide-based technopolymer, while the dipstick is made from AISI 304 stainless steel. The float is made from NBR synthetic rubber, supporting use in oil, water, coolant oil, and similar industrial fluids.
How the Level System Works
The product allows accurate set point definition by disassembling the dipstick float and cutting the dipstick exactly where needed. This makes the Elesa+Ganter 111281 HFL-EF-NO rapid level with float suitable for different reservoir depths and control requirements. The NO version means that the electrical contact opens when the liquid reaches the desired intervention level.
Application Advantages
The HFL-E series is useful where the liquid may contain dirt, foam, iron particles, or coolant residue. Its operation does not depend on the electrical conductivity of the fluid, which makes it versatile across many machine-building environments. Electrical components are separated from the tank and sealed, helping support safe use in demanding installations.
Installation Notes
The HFL-EF execution is assembled through a flange with three holes positioned at 120 degrees for the supplied zinc-plated steel screws. It can also be mounted with two holes at 180 degrees. The maximum continuous working temperature is 80°C, so the operating environment should be checked before installation.

Elesa+Ganter 111281 FAQ
What is the Elesa+Ganter 111281 HFL-EF-NO used for?
It is used to indicate and electrically monitor a predefined liquid level in tanks and reservoirs. It can support minimum or maximum level control depending on the installation.
What does NO mean in HFL-EF-NO?
NO refers to normally open logic. For this model, the electrical contact opens when the liquid reaches the selected intervention level.
What is the dipstick length?
The 111281 HFL-EF-NO configuration has a 500 mm dipstick length, making it suitable for medium-depth tank applications.
Can this product be used with coolant?
Yes. It is suitable for coolant oil, water, oil, and dirty liquids, provided that the material compatibility and temperature limits are respected.
Why choose a flange-mounted level indicator?
Flange mounting provides stable mechanical fixing on reservoir walls. It is useful when a secure installation is required in vibrating or machine-integrated environments.
