LevelAir - Level sensor
The level sensor for plant engineering
Automation starts with a reliable sensor.
Who doesn't know the hassle of analog and digital level sensors? Great system automation has been set up and it gets stuck because the level sensor gives it the wrong signal. Regardless of whether an ultrasonic sensor is misled by water vapor, foam or the sloping bottom of a tank, or whether mechanical floats become encrusted and get stuck, the system manufacturer or operator has the trouble and the costs. A.C.K. looks back on more than 10 years of experience in international special system construction and knows how important reliable level measurement technology is. The wheat is separated from the chaff, especially in sewage systems. We have condensed our experience into our own level sensor and have given it the properties that plant engineers need.
- Levelsensor is very cost effective.
- Levelsensor shows no corrosion.
- It contains no moving parts.
- Levelsensor has not to be calibrated by an official entity.
- A DC 4 - 20 mA output port is available to be used for an analogues input of an external controller.
- 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!
