Features

  • Micro-pulse achieves high accuracy regardless of the temperature and pressure change, vapor and dust of the tank
  • Density or temperature change of measuring liquid will not affect the measuring accuracy
  • Easy change of the basic settings and confirmation of the identifying value, with the display unit
  • Non-moving parts guarantee maintenance-free operation
  • Thanks to the 2-wire loop powered system, reduction of cable and installation cost are possible
  • Thanks to the 2-wire loop powered system, revamp from other devices is also available easily
  • The device is delivered with factory setting, and therefore no need for field calibration
