Portable Sounding Device

Portable Sounding Device – For easy, quick and accurate measurement of liquid substance with high transparency and low connectivity for a broad range of applications.

API Marine Portable Sounding Device is a stand-alone device, that complies with IMO’s new ship exhaust gas regulations as of January 1, 2020, in order to accurately measure the level to liquid in a tank.

API Marine Portable Sounding Device consist of a highly advanced and reliable sensor that streamlines the process of level measurement of the liquid in tanks, but also accurate measurements of bunkered oil in case of cappuccino bunker.

With API Marine Portable Sounding Device, you will be able to determine the distance from the point of measurement to the surface of the liquid with high accuracy as an alarm will sound when the liquid sensors comes into contact with the liquid inside the tank.

Main Advantages:

  • No sensitivity to foam
  • Short measuring time (Ullage measurement)
  • Possible to detect transparent liquid
  • Portable type
  • Weight : 1.36kg
  • Compact size
