Features

  • Cable cost can be reduced by the 2-wire system.
  • TDR (Time Domain Reflectrometry) system is available for various applications.
  • Measurement in high accuracy is realized by 2-wire loop powered system.
  • Improved sensibility due to sharper pulses generated.
  • Available for temperature and pressure in wide range. Measurement in high accuracy can be made regardless of the change in temperature, pressure and density.
  • Possible to install the level meter in narrow space because the micro-pulse is propagated along the probe.
  • Easy operation with wide graphic display.
