SAL R1a is the fourth generation acoustic correlation SAL speed log for measuring relative speed – speed through the water. The log is designed to meet requirements as specified by authorities and shipowners. Its performance exceeds the various IMO specifications and has proven reliability in many thousand installations worldwide.

SAL Speed logs has been well known to the marine industry since 1912. Today more than 5,000 systems are in operation. The present range of SAL Speed Logs are based on the acoustic correlation principle for both relative and true speed measurement.
The SAL Speed Log can today present a unique feature in a type approved combined speed log and echo sounder. This will give the ship owner a unique double function with only one penetration in the ship's hull.
SAL speed logs are clearly marked and meet all relevant requirements of IMO regulations, IEC standards and EU directives and are approved according to requirements of the Marine Equipment Directive (MED).
SAL T1 %u2013 Combined One-axis speed log and echo sounder. Measures longitudinal relative speed through water as well as bottom track speed in combination with water depth.

The JLN-205 Dopoier Los Is assigned as a device of ship speed measurement and information. Trie JLN-205 utilizing nigh frequency of ultrasonic wave brings hlgn stability and accuracy of speed measurement.
in addition, a miniaturized transducer will enable to install on tne bow where is m less influence against tiny bubbles.

SATLOG SLS 4120 - the BSH - type approved speed log system
according to IMOperformance standard for SDME (Speed and
Distance Measuring Devices) measures and displays with speed
over ground.Speed through water information can be displayed by
connecting a watertrack log.

The JLN-550 Dopaer Sonar providing ship speed information has higher stability in ihe dual frequency modes, and smaller size dual-frequency transducer to be easy installation and maintenance. The dual frequency mode function wll be superior in measuring of the ship's speed against the ground up to larger depths and also the water with tiny bubales
