Verification of fuel, AdBlue and LPG dispensers

When users fill up at a service station, they need to be assured that the fuel pumps and other products, such as AdBlue or LPG, are in perfect condition and that the quantities they dispense are accurate and reliable. Evolving European standards for regulating pollutant emissions have boosted the development of engines that can run on alternative fuels to actively reduce exhaust gases and pollutants. LPG is a widespread alternative fuel, as is natural gas (CNG and LNG) or vegetable oil for trucks. On the other hand, all diesel trucks and light-duty vehicles manufactured since October 2006 are equipped with a catalytic reduction system using AdBlue, an aqueous solution that converts pollutants into water vapour. 

Therefore, filling stations must be equipped with the appropriate pumps to dispense both conventional and new fuels and comply with the relevant standards, including the verification of the pumps.

What is

verification of AdBlue and LPG dispensers

The verification of fuel dispensers is governed by the provisions of ORDER ITC/3720/2006, of 22 November, which regulates the State metrological control of measuring systems for liquids other than water known as dispensers or dispensers.


For its part, the verification of AdBlue pumps by Order ITC/360/2010, of 12 February, which regulates the State metrological control of measuring systems for liquids other than water known as pumps or dispensers intended for the supply to motor vehicles of substances not intended for use as fuel.

Which equipment must be verified?


The State metrological control of pumps or dispensers concerns the in-service phase and includes both the verification after repair or modification and the periodic verification of the dispensers or dispensers.

Fuel dispensers/dispensers: measuring systems designed to supply fuel to motor vehicles, small boats and small aircraft, as defined in Annex IX of Royal Decree 889/2006, of 21 July, which regulates the State metrological control of measuring instruments.

AdBlue dispensers/dispensers: measuring systems for liquids other than water, called dispensers or dispensers intended for the supply to motor vehicles of substances not intended for use as fuel.
Eurocontrol is accredited by ENAC No. OC-I/271 to perform periodic verification and after repair or modification of dispensers at the in-service instrumentation stage in the following categories:

  • Fuel dispensers: Minimum measuring capacity, CMM > 2 l Maximum flow rate 200 l/min
  • AdBlue dispensers: Flow rate from 2 l/min to 50 l/min
  • LPG dispensers with max. flow rate ≤ 50 l/min


Under the accreditation as Inspection Entity EI007, we carry out the periodic verification of phase II petrol vapour recovery systems in oil installations for vehicle supply, in compliance with RD 455/2012, of 5 March, which establishes measures aimed at reducing the amount of petrol vapour emitted into the atmosphere during the refuelling of motor vehicles at service stations, as amended by RD 144/2016.

tyre pressure gauges
Verification of tyre pressure gauges
The stability, grip, cornering behaviour and braking performance of a vehicle's tyres must be optimal to ensure maximum safety. In addition, sufficiently inflated tyres can reduce fuel consumption, which is important in view of rising fuel costs. To be sure that the tyre pressure is correct, it should be checked regularly. The gauges we use for this purpose, both analogue and digital, should be checked for errors related to drift, environment, power supply, addition of components to the output loop and other process changes.

Inspection of oil installations
Industrialised countries accumulate oil reserves to be able to adjust supply in real time to fluctuating consumer demand. The storage of hydrocarbons also makes it possible to guard against international crises, or to preserve crude oil while waiting for its refining. Oil storage presents two major risks: fires and soil and groundwater pollution. Avoiding this pollution is a major challenge, for which Eurocontrol is involved in checking the condition of tanks and their degree of corrosion.
