The Handheld Depth Finder FT - CS150 is a professional device for detecting water depth. Its working principle is based on the characteristics of ultrasonic waves. When measuring the depth, the ultrasonic transducer is placed on the water surface or a specific position. Using the fixed sound speed VC of ultrasonic waves in water and the time T from the emission to the reception of ultrasonic waves, the instrument can automatically calculate the water depth H, thus quickly and accurately obtaining water depth data.
It is extremely convenient and can be flexibly installed outside (inside) the hulls of medium - sized and small - sized boats. It is also equipped with a 10 - meter cable for use in different working environments.
It adopts self - stabilizing measurement technology and fast - tracking technology, which can reflect the real measurement results in real - time and accurately. It is also equipped with a high - precision clock with an annual error of only 3 PPM. Its storage function is also excellent. It has a large - capacity SD storage with a maximum storage capacity of 32GB and can adapt to the FAT16/FAT32 file systems. It automatically stores data in CSV format files by date, which greatly facilitates data query and management. The high - brightness screen allows the measurement data to be clearly displayed even in strong sunlight in the wild. Moreover, the FT - CS150 has strong adaptability and can stably measure the depth both in still water and in water with a flow rate of about 5m/s.
The measuring range of the FT - CS150 is 0 - 150 meters, and the blind zone is only 1.5 meters. Its power can be automatically adjusted in 32 - level transmit power gain. The minimum display resolution reaches 0.1mm, and the accuracy can be controlled within ±1%× the measuring range. The display uses a Chinese - language LCD full - color screen, and the working frequency is 200 - 2000KHz. On - site settings can be completed through the sensor buttons. It has been calibrated at the factory and can also be calibrated on - site.
Data output and storage are very convenient. Data can be exported through a USB flash drive. The on - board FLASH automatically stores the measurement data in EXCEL files, with a maximum storage capacity of 5000 records. The working voltage relies on the built - in battery and can be externally connected to a charger. The keyboard uses numeric keys. The main unit is made of ABS engineering plastic, the sensor is made of ABS engineering plastic, and the measuring rod is made of stainless steel. The main unit weighs 300g, the sensor weighs 400 - 800g, and the diameter of the sensor cable is 5 - 10mm×10m. The working temperature environment requires ≤80% RH without condensation, and the storage temperature is ≤80% RH without condensation, from - 40℃ to 70℃.
