Attain Highly Accurate &Stable Speed Measurement

Better StabilityWith the new transducer and newly designed process algorithm,the impact of foam is reduced, enabling highly accurate and stableship speed information.

Highly Accurate Measurements

▶Development of a transducer equipped with the latest technology ①Usage of a high frequency with a strong foam resistance ②Achievement of an optimal ultrasonic width and angle▶Significant improvement of the signal processing capability

Improved Interference Immunity Comparison between the DS-80 valve (40kg)and the DS-85 valve (27kg)

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

Ship Speed Measurement Water Depth : 3m or deeper under the keel

The new compact and lightweight ball-type gate valve is30% lighter than the traditional valve. When replacingthe previous model (DS-80), the same tank or valve canbe used, reducing the cost of a retrofit.
