SAL R1a Easy Tank Speed Log

The SAL R1a is an IMO type-approved speed log for measuring longitudinal speed through water (STW), based on proven Acoustic Correlation technology. The speed log is designed to meet requirements as specified by authorities and ship owners, with performance exceeding applicable IMO specifications. Its closed-ended installation is simple and cost-effective, with no need for a watertight compartment or piping above the waterline.

 

 
  • High performance due to proven Acoustic Correlation technology
  • Flexible calibration allows highly accurate readings throughout the speed range
  • Easy set-up and calibration from the bridge display
  • Easy to install with only a few mechanical parts, lightweight bottom arrangements, and transducer mounting from inside the hull
  • Space saving with compact bottom arrangements
  • Safe due to a rugged mechanical design and watertight cable
  • Closed ended installation means no need for a watertight compartment or piping above the waterline
  • Pressure tested and approved according to PN16 (24 bar, 240 m)
  • Complies with IMO resolution A.824(19)

Overview

 
The SAL R1a is an IMO type-approved speed log for measuring speed through water (STW). It includes bottom arrangements, transducer, and electronics unit, all mounted in the bow area. A digital speed and distance display is also included for bridge installation.
 
Acoustic Correlation
 
Acoustic correlation is a proven and practical technology that measures sonar readings across two elements in a single transducer. This technology measures water speed slightly further away from the hull than electromagnetic technology and doesn’t require the angular corrections of Doppler technology. This translates into less corrections required in the speed calculation algorithm, delivering stable and reliable speed through water measurements.
 
Easy Tank for Easy Installation
 
The SAL R1a’s “Easy Tank” bottom arrangement provides a closed ended installation, with no need for a watertight compartment or piping above the waterline. The watertight arrangement is damage-resistant, and a watertight cable enables installation in wet environments. Bottom arrangements are available to suit both aluminium and steel hull constructions.
 
Connectivity
The speed log’s electronics are enclosed in a splash-proof steel box, which can be mounted up to ten metres from the transducer. The remote bridge display connects to the electronics unit via an industry-standard IEC 61162-1/NMEA 0183® interface; the electronics unit also provides pulse and voltage outputs for connection to alternative display devices.
