• Perfect solutions

    for the environmental/ recycling sector

The Environmental Sector

The environmental sector is facing the challenges of sustainable management and the careful and efficient use of natural resources. In addition, environmental legislation places high demands on the waste and recycling industry. Here you will see from practical examples how the level measurement technology from UWT is able to adapt to and meet these new requirements.   

The challenge

A company near Moscow supplies aluminium alloys made from recycled aluminium (bins, broken aluminium, cinder from the first production). In the exit of the furnance, gases with chalk powder are cleaned which is filtered and filled in a big bag afterwards.

Our solution

The vibrating level limit switch VIBRANIVO VN4020 is the best solution for this application. It was installed in the tube of the big bag as full detector. The aggressive chalk powder cannot damage the stainless steel extension (316L) and the whole unit is absolutely dense. The process temperature starts from -40° up to +150°C which is an important attribute in the Russian market. As a result, the great cost-/performance ratio convinces all of our customers.

Products

With the following products our customer has solved this measurement task optimally:

The challenge

Our customer required to monitor the fill level of ash from waste incineration. The material is pneumatically fed into storage silos. Because of the strong stickiness of the material it is possible for steep material cones to build up during pneumatic pumping. The temperature of fly-ash during filling is approximately 130°C.

Our solution

The UWT lot system NB 3000 fulfills these requirements. The sure to function high-tech lot offers a high measurement accuracy and reliability which is not adversely affected by the rough conditions in the settlement tank. The NB 3000 is mounted and after easy programming, is ready for operational usage.

The challenge

Our required the full detection in a filter dust storage container. It was important that the measurement technology could operate in temperatures of 100°C whilst ensuring reliable sensitivity, and in addition being sufficiently resistant to various acids and gases.

Our solution

The UWT rotating paddle detector ROTONIVO RN3000 series meets these extreme measurement requirements. This is made possible through the RN3000´s high quality allowing exact measurement customised to the density of the bulk goods and optimal sealing against dust. The product contact parts are constructed from VA and can also be PFA sealed when required. With these features this series is predestined for such applications in many areas of the environmental sector.

Products

With the following products our customer has solved this measurement task optimally:

RN 3004 Horizontal Tube Extension

Full, Demand, Empty Detector
Protection tube version

  • Horizontal, vertical and diagonal installation.
  • Extremely robust due to protection tube, able to withstand heavy mechanical load.

The challenge

Our customer required to monitor the fill level of the filter inlet in the coal filter. As a result of certain exhaust gas norms being changed, a coal filter had to be installed a few years ago. The temperature of the filter is approximately 130°C.

Our solution

The UWT vibrating fork probe VIBRANIVO VN2020 fulfills these difficult requirements. The VN2020 temperature version can be used in temperatures of up to 150°C. The highly sensitive VN2020 reliably measures filter dust density upwards of 5 g/l. Only since the installation of the UWT tuning fork, has it been possible for the incinerator to function trouble-free.

Products

With the following products our customer has solved this measurement task optimally:

VN 2020

Full, Demand, Empty Detector
Short version

  • Vertical, horizontal and oblique installation.
  • Compact extension length: 235mm.
  • High sensitivity from 5g/l.

The challenge

Our customer required to measure the sludge level in a lamellar separator. The contaminated water comes from a large metal recycling plant, and the sludge level measurement is used to control a pump, which pumps the sludge into a press.

Our solution

In this particularly difficult application, the UWT VIBRANIVO VN1000 vibrating fork with a specially developed electronic module for interface measurement is ideal. The adjustable sensitivity means the sensor can be set to the required switch point. The VN1000 functions maintenance-free and has also been well proven in other interface applications. The excellent cost-/performance ratio is another plus in comparison with other measurement principles

Products

With the following products our customer has solved this measurement task optimally:

VN 1030

Full, Demand, Empty Detector
Tube extension version

  • Vertical, horizontal and oblique installation.
  • Mechanically highly durable due to short vibrating forks.
  • Shaft length up to 4000mm available.
  • Flexible height adjustment
  • Also suitable for Interface measurement.

The challenge

Our customer required to monitor the contents of a foil cuttings storage silo. The extremely light bulk density and the undefined surface level required a very sensitive measurement. The foil comes from recycling plants and is detached from tetra packs. The foil cuttings are then used as raw material for further foil production. The fill level is monitored via visual display and is linked to the plant control system. Ultrasound equipment has so far been unsuccessful.

Our solution

The UWT lot system NB 3100 fulfills these requirements. The sure to function high-tech lot offers a high measurement accuracy and reliability by using a folding canvas parachute sensor weight. The NB 3100 is predestined fur such difficult applications in which other measurement technology has been unsuccessful.

  • Convenient level monitoring via Modbus interface together with price competitive Nivotec 3500/4500.

The challenge

One of our customers in Slovakia requested a reliable and cost-effective solution for the limit detection of flying ash in their collecting vessel. The particular challenge is to install a technology which withstands high temperatures of up to +600°C and which can be installed despite the tight space (only horizontically).

Our solution

The rotating paddle switch ROTONIVO RN3004 (special high temperature version with variable protection cover fulfills these requirements. In all, 25 units have been installed that deliver reliable and precise results.

Products

With the following products our customer has solved this measurement task optimally:

RN 3004 Horizontal Tube Extension

Full, Demand, Empty Detector
Protection tube version

  • Horizontal, vertical and diagonal installation.
  • Extremely robust due to protection tube, able to withstand heavy mechanical load.

The challenge

Our belgian customer already had installed many limit detectors like capacitive switches in his plants. The former expensive units combined with the complex installation and set-up could not solve the full detection in the customer’s preferred way. Above, the sensors rusted fast and had to be calibrated regularly. Alternative pressure sensors caused problems with vacuum during the processing.

Our solution

The rotating paddle switch ROTONIVO RN3002 as temperature version with up to 350°C, bearing at the tube end and 3-wire at the housing fulfilled all of the customers needs. He received reliable results with a maintenance-free, trouble-free and robust UWT technology.

Products

With the following products our customer has solved this measurement task optimally:

RN 3002 Tube Extension

Full Detector
Tube extension version

  • Vertical or oblique installation.
  • Protection tube ensures high mechanical load strength to the shaft.
  • Flexible height adjustment.

The challenge

Our customer, from the Russian Federation, recycels bottles. He asked for a limit detection in a vessel with snippets to be cleaned with a rinsing solution. The problem is the size of the snippets and the strong deposit build-up of the material. This interface measurement can not be solved with a vibrating probe.

Our solution

The rotating paddle switches of series ROTONIVO RN4001 have been installed at the top of the vessel. In there, the bottle snippets are cleaned from dirt, tags and lids with the rinsing solution. The process temperature is +40° to +80°C. Moreover, a mixer, steam and rough conditions make up further problems. The sensors with pendulum shaft extension have been installed at different points to ensure an optimized filling of the vessel. The rotating paddle switches are integrated in the management of the filling screw. The housing and the process connection made of plastics PA6 are resistant to the aggressive and humid medium of the rinsing solution.
