E+H Levelflex FMP52 Guided Radar Transmitter

Levelflex FMP52 for level measurement in aggressive liquids with chemically resistant gap-free PFA-coated probe. All wetted parts are FDA listed materials. FMP52 guided radar offers maximum reliability even in case of moved surface. Levelflex FMP52 is used for continuous level measurement of liquids, pastes and slurries but also for interface measurement. The measurement is not affected by changing media, temperature changes, gas blankets or vapors.

  • Reliable measurement even for changing product and process conditions
  • HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics
  • Highest reliability due to new Multi-Echo Tracking evaluation

  • Application limits

    High process temperatures (> 150 °C/302 °F) can favor diffusion of the process medium into the probe coating which may lead to a limited lifetime. FMP54

    Interface measurement: Use coax system in favor (coax probe, bypass, stilling well) 

    Interface with emulsion: FMP55
