DIGITAL TANK MONITORING FOR BULK FUEL AND DEF INSTALLATIONS
Digital level gauge with 3-metre probe for diesel, AdBlue and oil storage tanks. CE certified with NBR seals for broad fuel compatibility.
What it does
The T5020 is a digital level gauge with a 3-metre probe that drops into your diesel, AdBlue or oil tank and gives you a continuous readout of what is left. No more climbing on top of tanks with a dipstick, no more guessing when to reorder. The NBR seals handle petroleum fuels and DEF without degradation, and the CE certification covers the compliance requirement for fixed storage installations.
Who it suits
Workshop managers with bulk diesel or AdBlue tanks who need to track consumption without manual checks. Construction sites running multiple machines where you want early warning before the tank runs dry. Oil storage depots where daily dipping is a pain. The 3-metre probe fits most common workshop and site tanks; if your tank is taller, this model is not the right match.
