The level sensor for constructors

Who does not know the trouble with analogous and digital level sensors? One has installed a fully automatic installation and it fails because a level sensor gives a wrong signal or no input. It does not make a difference whether it is an ultra sonic sensor which is disturbed from vapour, foam or a bevelled bottom of a tank or it is a mechanical floater which jams caused on fouling or mechanical blocking. Always the supplier of the installation or the operating company has to cover trouble and expense.

Your advantage:

  • Levelsensor is very cost effective.
  • Levelsensor shows no corrosion.
  • It contains no moving parts.
  • Display of the filling level in m and in % as well as display of the volume in m³. The display is illuminated.
  • The density of the liquid is adjustable.
  • Levelsensor has not to be calibrated.
  • There are four dry contacts available which are switching at different and adjustable levels. They can be used as normally open contact or as break contact element to switch up to 1 Ampere.
  • A DC 4 - 20 mA output port is available to be used for an analogues input of an external controller.
  • The damping of the signal is adjustable.
  • The level signal will not be impacted from a varying pressure in the tank atmosphere.
    Extremely low consumption of air and electricity.

Principle of operation
A pressure sensor measures the static pressure in a dip tube without contacting the fluid.
Levelsensor is fixed with a threaded socket (DN25) on top of a dip tube which leads to the
bottom of the tank.
Inflowing air prevents that the liquid comes up the tube. So it is ensured that no corrosives gases or vapour damage the pressure sensor.
A pressure compensation pipe corrects the level measuring. So a varying pressure in the tank atmosphere will not affect the measurement.
Plug and play. Use only the standard threaded socket (part of the delivery volume) to thread it on top of a dip tube, connect the cables to the generous designed clamps and finely connect it to the pressured air which is normally always available.

That’s all!
