Smart Sounding Scale “Honesty” Is Now Available

“Honesty,” an efficient tank sounding* device (patent pending) that improves the accuracy of measurements of the surface of liquid, developed by MTI and Nippon Yusen Kabushiki Kaisha (NYK), and Semco Ltd., is now available.

*Tank sounding
Measuring the depth of liquid stored in a vessel tank or the distance from the top of a tank to the surface of a liquid.

  • A buzzer indicates that the measurement is complete, and the accurate value is quickly provided.
  • Improves measurement accuracy and shortens tank-sounding time 30% compared to conventional products.
  • Measures not only fuel oil but also clear colorless liquids such as sea water and bilge water.
  • Convenient to carry around as it is portable and requires no external power supply.
