SAL R1a Easy tank

Description

The easiest SOLAS Speed Log to install. SAL R1a Easy Tank is the fourth generation acoustic correlation SAL speed log for measuring relative speed – speed through water (STW) . The speed 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.

Main features of the SAL R1a Easy Tank

• Closed ended installation - no need for water tight compartment or piping above sealine.
• Easy to install, with only a few mechanical parts and light weight bottom parts. 
  The transducer mounting is made from the inside of the hull.
• Safe due to the rugged mechanical design and water tight cable.
• Pressure tested and approved according to PN16 (24 bar, 240 m).
• High performance because of the proven Acoustic Correlation technology.
• Space saving with the small and compact bottom parts
• Easy set-up and calibration procedures from the bridge SD4 displays.
• Flexible calibration allows very accurate reading over the speed range.
