Tecfluid S.A products

By means of float with magnetic field and reed switches. One or more reed switches are placed at a specific height inside a guide tube. The changes in liquid level modify the float position in this guide tube, so that when it reaches the switch position, it changes its status, providing an output signal for level detection.

Float level switches. When a liquid reaches the level where the level switch is positioned, its float follows the level variations in a such way that the articulated rod is moved. A magnet placed in the opposite side of this rod activates a switch. This switch can be either a micro-switch, a reed switch, an inductive detector or a pneumatic switch, depending on the application requirements.

Vibrating fork level switch for liquids and solids. Compact and Robust. High resistance to high temperatures and pressures. Possibility of selection of activation, with or without the presence of product, and detection of granular solids. No moving parts and low maintenance.

A reed switches / resistance chain is mounted inside a guide tube. The changes in liquid level modify the float position in this guide tube, so that it activates the reed switches providing an output signal of variation of resistance, which can be later converted into an analog output of voltage or current.

According to Archimedes principle of body submerged in a liquid. A float with a density similar to the measured liquid is suspended by a spring to maintain an equilibrium with its weight. This float is always submerged in the liquid (not floating on the surface). A variation in the liquid level  produces a change in the weight of the float (partially submerged), which can be measured by the extension or compression of the spring that supports the float . The variation in the length of the spring is transmitted to the indicating needle via a magnetic coupling .
