The following report details the functionality of the EESiFlo EASZ-1 during a recent evaluation at a large commercial Oil plant in South-East Asia. This plant receives tanker truck loads of unrefined oil from remote producers. The plant owner suspects that water is being added during transport to increase the value of the delivered product.

The EASZ-1 has been used in similar applications where the quality of oil or fuel has been compromised but it was important for this clients to test the applicability of the water sensor in situ before ordering multiple units. A single 4 inch EASZ-1 was installed on the transfer line between the tanker trucks and the plant. When the trucks unload, the EASZ-1 measures the product as it leaves the truck with the goal of accurately determining the quantity of water contained in each truck.

Conclusions

The test performed by adding water to the third tanker proves the EASZ-1 is very capable of achieving the level alarms that the customer wants to achieve. These particular applications are looking for larger amounts of water, so the offset set off by changing density will have a minor effect the percentage readings . The EASZ-1 is a practical device to be used in loading stations on various types of oil or fuel. The current new development is the intrinsic safe unit Eex ia IIB T4 which has now received official ATEX certification.

In these applications, the factory pre-calibrated 4 inch EASZ-1’s will be programmed to indicate “Zero” on typical low density oils. Each EASZ-1 unit to come with a factory pre-setup display with relay output to activate on pre-defined water content.

Included here are data from the third and fourth truck unloading.
