Optimal Fuel Quality - Reliable Power | Keeping the Lights on

In Line Quality Measurement

In line real-time measurement of product quality is becoming more important. Two key factors that can be measured in line are water content in ppm and particle size distribution according to ISO 4406:1999. Njord offers both measurement systems that can easily be integrated with our range of automated filtration systems and represent a remarkable cost effective solution to fluid management and contamination control.
- the Zelentech Water in Oil meter delivers continuous, real ime accurate monitoring of the ppm concentrati.on of ALL water (free, dissolved as well as emulsified).
- the Parker i-Count combined with Njord flow control offers laser based leading edge technology.

Zelentech Water in Oil Monitor

Zelentech water in fuel meters

Water contamination in fuels and oil based fluids can cause numerous problems such as loss of revenue, additive depletion, oil oxidation, corrosion, reduced lubricating film thickness, accelerated component wear rates, microbiological growth, reduction of dielectric strength and loss of power.

The Zelen Tech Water in Oil (WIO) monitor can help prevent such problems associated with water contamination in oil based fluid systems.
