Our Application Handbook contains a Guidance Chart for selecting a suitable level measurement instrument for a given medium and our readers can read more than 50 application case studies and many short references from all around the World.
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.
2010 - Steel-works in Dunaújváros, Hungary - Coke-works,
Measurement of different types of coal powders in extreme dusty and ’Dust Ex’ environment with ultrasonic level transmitters. After separation of the finished product, level switch is performed with Ex-type vibrating forks.
• EchoTREK SBD-31J-8 Ex 14 pcs
• NIVOSWITCH RLH-304-E Ex 4 pcs
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.
