In the so-called contact manufacturing process of sulphuric acid continuous level measurement solution is needed for the mixing tank where oleum is diluted with water. The conditions in the tank were very challenging. There is the very aggressive atmosphere with strong fumes added with level fluctuations and not to mention the high humidity. The MicroTREK Guided Wave Radar is perfectly protected against any chemical reaction because all parts are covered with PFA/FEP coating providing long-term reliable level measurement.
Instrumentation for chemical storage tanks that needed to be continuously measured with a high level alarm indication and completed with a complex controlling system. The outside horizontal cylindrical tanks and are regarded as ATEX, hazardous environment, therefore all the elements of the measurement system must be intrinsically safe

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.
GSK is one of the most well-known medicinal chemistry and vaccine producers all over the world. In the Hungarian facility of GSK they use CIP Cleaning-In-Place / SIP Sterilization-In-Place processes in order to provide the required high purity for the medicinal production. These cleaning processes use low concentration acid materials which is in this case is sulphuric acid, stored in 1m3 (35.3 ft3) moveable vessels. The level measurement of the removeable sulphuric acid storage tanks is solved by a PiloTREK Pulse Burst Radar equipped into the openable top over the tank. The speciality of the application that the PiloTREK Pulse Burst Radar measures the level through the plastic tank wall.
A creamery in the Czech Republic produces milk products and uses some types of corrosive chemicals for example in the cleaning process where the level measurement of these mediums are really challenging
for all instrument manufacturers. The chemicals are stored in 2 closed 1 m3 (35.3 ft3) sized plastic tanks.
The customer’s demand was to continuously measure the level
of the chemicals using non-contact radar measurement through
the plastic tank wall.
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.

NIVELCO solid level measurement instrumentation can be employed in practically all phases of limestone processing. The EchoTREK STD / EasyTREK SCD ultrasonic or the MicroTREK TDR level transmitters are ideal choice for accurate level measurement in extremely harsh, dusty circumstances.
Prior to sealing the green peas and corn cans the food is filled with a special juice that provides the flavour of the product. The storage and the mixing tanks containing the filling liquid are measured by MicroTREK guided wave radars.
Continuous level measurement of different pH and density liquids for example high purity water, washing
liquid, and fermentation liquid with high temperature MicroTREK guided wave radar level transmitter, meeting high hygienic requirements in the pharmaceutical environment.
The subject of the measurement task is 160 °C (320 °F) bitumen in order to proper stock management. The level in the 7.9 m (25.9 feet) high tank is measured by a PiloTREK WHS-150-4 high temperature type unit. The PiloTREK is connected to a data logging capable MultiCONT PRD-210 process controller unit to monitor the measurement data.
The major instrumentation investment project of Agrokémia Sellye chemical plant in 2011-2012 was continued with the measurement of buffer tanks. The pesticide containing tanks are measured by guided wave level transmitters with 4mm diameter cable probe. The avaiable space above these inside tanks is very small, so rigid rod probe versions cannot be mounted.

Sugar crystallization pan application: The application is very tricky since the sugar syrup in the pan (tank) is vacuumised at 600–700 mmHg while operating temperature is held at around 80°C. The syrup is continuously stirred by an 40-50 rpm agitator. Due to the evaporation and addition of crystal seeds the syrup if finally converted into crystals.
