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.
Mediterrán Zrt. in Bóly manufactures important "element" of building industry, the roof tile. Production of concrete tiles needs many types of raw materials, such as sand, cement, dyes, and auxiliary materials which are stored in silos. These silos are measured by MicroTREK guided microwave level transmitters with 8mm cable probe. High fail-safe monitoring is done by NIVOROTA rotary paddle level switches.
The high temperature version MicroTREK guided wave level transmitters with mono rod probe measure bitumen in a feeding tank. The instrument operates with high reliability in the high temperature (180°C) environment and sticky medium application.
