Online measurements are now possible using the EESIFLO mini EASZ-1.

Biodiesel is hydrophilic. Some of the water present is residual to processing, and some comes from storage tank condensation. The presence of water is a problem because

1. Water reduces the heat of combustion of the bulk fuel. This means more smoke, harder starting, less power.
2. Water causes corrosion of vital fuel system components: fuel pumps, injector pumps, fuel lines, etc.
3. Water freezes to form ice crystals near 0 °C (32 °F). These crystals provide sites for nucleation and accelerate the gelling of the residual fuel.
4. Water accelerates the growth of microbe colonies which can plug up a fuel system. Biodiesel users who have heated fuel tanks therefore face a year-round microbe problem.

Previously, the amount of water contaminating biodiesel has been difficult to measure by taking samples, since water and oil separate. Getting a representative sample is practically impossible. Although lab methods can accurately measure water in an oil sample, it is too difficult to obtain a small sample that represents the total amount of water in the fluid.

However it is now possible to measure the water content using EESIFLO EASZ-1 online water sensors. This means that 100% of the biodiesel passing through the process is being monitored 24 hours a day.

The EASZ-1 water sensor has its sensor elements made out of stainless steel. The method used is accurate detection of changes in dielectric of the fluid. Since the biodiesel and water have very different dielectric constants, a tiny or large amount of water can be accurately measured due to the permittivity change. The EASZ-1 does this online in real time so that moisture or free water contamination can be detected immediately. Built in temperature sensors connected to the PCB allow the units to monitor a change in temperature so that the measurements can be compensated when the oil is heated or cooled . This improves overall accuracy. Once the sensor is installed, there is little or no maintenance since the sensing elements are made up of two solid tubes which act like two separated plates measuring capacitance of the media in between. The response time for the EASZ-1 is approximately 1 second and the measuring ranges can be changed by the user from 0-1%, 0-3%, 0-10% and 0-25%. Higher versions are also available on request.

The EASZ-1 water sensor is a development that started in the early 90’s with a view to designing and producing a reliable and cost effective water in oil sensor with rapid detection capability and above all, something that was easy to use and maintain.
