Along with the soared fuel price in recent years, measures against degrading fuel used for ships have been drawing world's attention as a part of energy-saving. The practical applications have been advanced step by step and 6000 sec RW No.1 as the target fuel in the years to come. NS777C (Viscosity-Transmitter Unit) developed this time as a measure against degrading fuel is a version of NS777 series capillary type Viscosity-Transmitter Unit which has the proved performance over the past 20 years, and has improved reliability greatly through a number of improvements in the performance such as elimination of the pulsating pressure noise generated by the injection pump of diesel engines while employing a double gear pump system.
