The main product of Hartmann Hungary is paper egg tray which is manufactured from recycled paper waste. The pre-processed paper waste should be cleaned from the painting materials mainly for optical and for chemical protection reasons. This so-called „deink” process use Hydrogen peroxide which is stored in a large outside plastic tank. The continuous level measurement is solved with a PiloTREK Pulse Burst Radar, high / low fail safe alarm is provided by NIVOSWITCH level switches and the temperature should be also measured. The challenging measurement conditions are high temperature and strong condensation, this is the reason that the PiloTREK level transmitter is equipped with PP antenna enclosure.
MOVI 2000 made several construction works recently for example in Debrecen or in Mosonmagyaróvár where the newly built feed plants required numerous level instrumentation eqipment. The different sized stock storage silos has been equipped with cable extended probe NIVOROTA rotary paddle level switches as high fail safe limit indicator. The units are Dust-Ex versions to meet the operation requirements. Due to the slight changes in the density of the stored feed the level switches have three-vane paddle.

Our partner is a Hungarian facility of a leading European manufacturer of polystyrene extruded foam insulation boards where the raw material storage tanks needed to be continuously measured. The customer is interested about the volume in the two tanks and it is calculated from the measured level value provided by coaxial probe type MicroTREK guided wave radars. The measurement data is displayed by UNICONT PMM units which are responsible for the batch controlling. There is an additional high fail-safe protection done by a NIVOSWITCH mini compact vibrating fork level switch. The complete measurement system has intrinsically safe protection.

2012 - Győr Distillery Co. Ltd., Győr, Hungary,
Győr Distillery Co. Ltd. produces ethanols in high quality and they use EchoTREK compact ultrasonic level transmitter in the alkaline tank of the fermentation process. The measured values are displayed on the outside UNICONT panel instrument. The overfill protection is performed by PFA coated NIVOSWITCH vibrating fork level switch.
The Agrokémia Sellye chemical plant made a major instrumentation investment project in 2011-2012. The pesticide containing batch-tanks are measured by magnetostrictive level transmitters with 95mm diameter float and two tanks are equipped with vibrating fork level switches for overfill protection.
The oil forwarding pumps of a Hungarian oil & gas retailer use API standard sealing liquid. The tanks containing this sealing liquid are equipped with NIVOPRESS D pressure transmitters besides the NIVOSWITCH low and high limit level switches. The control system uses the output signals of the UNICONT PKK current controlled switches which are connected to the NIVOSWITCH vibrating forks.
Gestamp, leading automotive parts manufacturer has a multi-thousand square-meter painting factory in Mór, Hungary. There an important technological process is the dust purification of the air. So the dust containers of the air purifier equipment need to be monitored and replaced when full. Level switching task is done by NIVOSWITCH vibrating forks for solids.
Level measurement of special technologic liquid - so called drilling mud with ultrasonic and microsonic level transmitters in storage silos. Low and high level switching of the silos are performed with float level switches.

Technological equipments used in processes of water treatment work correctly only under appropriate conditions of flow, level, pressure and temperature. That is why measurement and control of these parameters is very important.
2009 - Central European Gas Terminal (Közép-Európai Gázterminál), Dunaalmás, Hungary,
LPG level measurement in hazardous environment with magnetostrictive level transmitters validated by the NMI (National Metrology Institute). High accuracy (1mm) measurement has been achieved to meet the regulations of excise laws. Due to the low specific gravity of the medium the 95mm float was installed.
