With the NA-V4A glass level indicator, the liquid level in a tank can be read directly. A perforated metal cylinder allows level indication while also providing excellent mechanical protection for the glass tube. Each end is finished with a straight connector. A polypropylene float with an integrated magnet enables the activation of contacts mounted and fixed on the outside of the level column.
