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

the verification of AdBlue and LPG dispensers?

The verification of fuel dispensers is governed by the provisions of Order ICT/155/2020, of February 7, as amended by Order ITU/1475/2024, of December 17, which regulates the State metrological control of measuring systems for liquids other than water called dispensers or dispensers.

For its part, the verification of AdBlue pumps by Order ICT / 155/2020 of 7 February, amended by Order ITU/1475/2024 of 17 December, which regulates the State metrological control of the measurement systems of liquids other than water called pumps or dispensers for the supply to motor vehicles of substances not intended for use as fuel.

Which are the equipment to be verified?

The metrological control of the State on the dispensers or dispensers refers to the phase of instruments in service and includes both the verification after repair or modification and the periodic verification of the same.

Fuel dispensers: systems for the continuous and dynamic measurement of the quantity of liquids other than water, as defined in Order ICT/155/2020 of February 7, 21 July, which regulates the State metrological control of measuring instruments.
AdBlue dispensers/dispensers: systems for measuring liquids other than water, called dispensers or dispensers intended for supplying motor vehicles with substances not intended for use as fuel.

Apave is accredited by ENAC No. 6/EI653 to carry out periodic verification and after repair or modification of dispensers in the in-service instrument phase in the following categories:

Fuel dispensers: Minimum measurement 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 6/EI653, we carry out the periodic verification of phase II systems for gasoline vapor recovery in oil installations for supplying vehicles, in compliance with Royal Decree 45/45 of the European Parliament and of the Council of Ministers of the European Union.In compliance with RD 455/2012, of March 5, establishing measures to reduce the amount of gasoline vapors emitted into the atmosphere during the refueling of motor vehicles at service stations, as amended by RD 144/2016.

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 fire-fighting installations

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 Apave is involved in checking the condition of tanks and their degree of corrosion.
