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
