HD500 series | Ultrasonic Level meter|HD500-C / HD500-D
[Measurement Equipment [ Level meters ]]


  • Hiring high frequency ultrasonic system enables small dead zone and is possible to measure short distance.
  • High resolution, 0.1 mm
  • Minimize the main unit and sensor unit, so easy to install to the limited area.
  • Sensor part is chemical proof plastic (PFA).
  • Equipped RS-232C interface, 4-20 mA current output, Alarm output allows to communicate with existing system.
  • Flow measurement by measuring catchment level is possible.
