The proposal from the International Maritime Organisation (IMO) to limit further the emissions from marine diesel engines came into effect in May 2005. This has considerable consequence for the management and operation of ship diesel plant. One method that has been shown to limit the emissions of NO x is the addition of quantities of water as an emulsion into the heavy fuel oil (HFO) before it is injected into the burners. This reduces the peak combustion temperature, improves atomization of the diesel fuel, and can reduce emissions by as much as 30 per cent. A key component for an efficient and cost-effective system is a method to monitor the water content to an accuracy sufficient to allow the mix to be adjusted to meet the needs of the varying engine loads.

The EASZ-1 is a dielectric based device manufactured and supplied as an off the shelf water monitor for these applications in sizes ranging from 1 inch and above. The units are IP66 rated and fabricated in all stainless steel with water protective seals to protect the electronic circuitry. Temperature compensation has been implement in the design to increase the accuracy in applications where temperature fluctuations may be experienced in differing applications. The EASZ-1 is a low powered loop device which can be installed in new set ups or retrofitted to existing lines. Calibration of the EASZ-1 can be traced back to ASTM laboratory methods which can easily be conducted on site or in the factory.

EESIFLO International is an ISO 9001:2000 manufactured of quality liquid measurement instrumentation audited by SGS and has its manufacturing facilities in Singapore which is rated as one of the busiest sea ports in the world.
