Highly Accurate Measurements

When a vessel moves through the water, acoustic noise is created and is known as a boundary layer. This noise layer can cause errors with acoustic devices. By measuring speed through water (STW) farther away from the keel, the DS-85 penetrates through this noise and boundary layer resulting in a more stable and accurate speed measurement compared to an electromagnetic speed log.

Better Stability

With the new transducer and newly designed process algorithm, the impact of foam is reduced, enabling highly accurate and stable ship speed information.

Improved Interference Immunity

• Development of a transducer equipped with the latest technology
1. Usage of a high frequency with a strong foam resistance
2. Achievement of an optimal ultrasonic width and angle
• Development of a transducer equipped with the latest technology

Compact Gate Valve (Option)

The new compact and lightweight ball-type gate valve is 30% lighter than the traditional valve. When replacing the previous model (DS-80), the same tank or valve can be used, reducing the cost of a retrofit.
