Distributed THERMOPROPHILEMERS for marine use

It is designed to measure the continuous temperature profile in aquatic environments from the shore, coastal structures and various carriers and watercraft in autonomous or telemetric modes.

A distinctive feature of the device is the principle of measuring the temperature profile, based on the decomposition of the profile function in a series of Walsh functions, which reduces the error of spatial sampling and eliminates the need for scanning by a probe.

    Algorithmically, the software of the thermoprophilemers provides for the processing of measurement data on a PC in real time and in post-processing mode with the representation of data in the form of instantaneous temperature profiles, the course of temperature over time in all areas of spatial resolution in the form of a gradient and temperature isolines. In the autonomous operation mode of the device – archiving and transmission of measurement data via the Internet and via communication channels.

   Example of recording measurements of a vertical temperature profile by a 32–meter distributed sensor mounted vertically on an oceanographic platform (1-11 meters – air environment, 12-32 meters – sea water):
