Fill level measurement

Together with partners TELE is currently developing a practical method for linear conductive fill level measurements

Level monitoring of liquids

TELE is taking a new approach, and has system solutions for various applications within its programme.

 

At a glance

Fill level measuring or level monitoring is a frequently required procedure in the process industry, in food technology and also in the area of water & waste. Various measurement methods are used by which the fill level of a medium in a container is captured and converted into an electronic signal. The fill level signal is then either displayed directly on-site or integrated into a process control system to switch a relay. TELE is taking a new approach here, and has system solutions for various applications within its programme. The next exciting project: Together with partners from the water & wastewater sector, industry and university research, TELE is currently developing a practical method for linear conductive fill level measurements.

Function

The linear, conductive fill level measurement will have conventional conductive probes in combination with a microprocessor with appropriate evaluation calculations that will be used to provide reliable data. The electronics for measurement are located outside the container, which significantly increases the service life.

Added value

  • Research-based cooperative development of new processes
  • Already proven electronic applications:
    • Robust and durable
    • Regardless of medium and temperature

Application fields

The system is extremely robust and, in addition, it takes into account the conductivity of the medium. As a result, it can be used universally, for example in explosive areas, in the regulation of containers in the waste water industry, for industrial process water, in power plants, in the pharmaceutical industry or in the food industry.

Proven practical solutions

For conventional applications, TELE is also using already established solutions, such as the G2LM20 multifunction relay. The device has galvanitic isolation between supply and measuring circuits, even in the case of DC voltage, and enables fill level monitoring of conductive liquids with separately adjustable on and off delays and various selectable functions, such as pumping, minimum monitoring, pump down and maximum monitoring. It is mainly used where a mechanical solution for level monitoring is not possible, because the consistency of the liquid creates adhesion between the float switches and foreign materials.
