The OLE Z5020 ATEX Tank level gauge is an accurate continuous reading tank gauge with local alarm functions and an array of outputs which is suitable for low flashpoint fuels. The Z5020 tank gauge is designed for monitoring the levels of hazardous liquids such as kerosene or petrol stored in vented tanks.
Suitable for tanks up to 3m deep, an Ex rated level sensor is installed through the top of the storage tank using a 1" BSPT gland entry.
In order to comply with ATEX certification, the Z5020 display is to be installed within a Zone 2 / safe area and is connected to the intrinsically safe sensors via the integral barriers.
Using the hydrostatic principle, the backlit display gives a constant reading of the tank contents which is within ± 0.25% accuracy.
In addition, the Z5020 tank gauge features 4 software-programmable level alarm outputs.
