Cylindrical measuring system vehicle by Willig

Immeasurable quality

Equipped as an AT vehicle with a measuring system, the vehicle can be used to carry 1202 diesel / heating oil. It features two separate dispensing systems and can thus also be used as an FL tanker to carry 1203 gasoline.

Technical data


The following tank contents and compartments have become the established standard:

  • AT version: 36,000 to 38,000 with 2 to 5 compartments
  • FL version: 40,000 to 43,000 l with 3 to 5 compartments

Spill box options

Spill box are welded liquid-tight across the entire tank length as standard. In the case of semi-trailer tankers with one to three compartments, it is possible to incorporate shortened spill boxes. The ladder is available as a removable and telescopic version. A corrugate aluminium plate on the edge of the spill box offers protection against damage when filling from above.


A continuous cabinet with parallelogram or swivel doors is positioned in front of the axle for the measuring system(s). The hose reel can be positioned in the cabinet, in the auxiliary cabinet or as an axial hose reel in front of the end bottoms.

Loading / Discharging

Loading options

  • Top loading via man hole
  • Bottom loading via loading coupling
  • Manual loading via suction

Discharging facilities

AT semi-trailer tanker for 1202 diesel/heating oil
Discharging generally takes place using a pump measuring system for low-viscosity mineral oils with a wet hose and/or dry hose. The storage tank is filled via an unmetered outlet.

FL semi-trailer tanker for 1203 petrol and 1202 diesel/heating oil
Separate discharging systems with a pump measuring system with wet and/or dry hose for diesel/heating oil and a further gravity measuring system with dry hose for petrol discharging.


Our semi-trailer tankers can be fitted with the following electronics:

  • Temperature compensator/controller incl. printer
  • Loading hose protection system for the proper connection of hoses
  • Cross Over Prevention for the correct allocation of the product
  • Sealed Parcel Delivery System (SPD)
  • Monitoring of the cabinet doors


  • Deadman button
  • Overfill protection system with cross over prevention sensor cable
  • GPS integration
  • GSM data transfer system

Brakes / Air suspension

Braking comfort improved with integrated EBS/ABS brake system and RSS function. Vehicle safety can be increased through selective braking in the case of risk of tipping.

  • The EBS function accelerates reaction and pressure build-up times in the brake cylinders. This reduces the stopping distance by a few metres.
  • Driving stability is assured by the ABS function during the braking process.
  • The RSS function uses selective braking to prevent the tanker from tipping, jack-knifing or skidding.
  • The trailer air suspension can be managed mechanically via an air suspension valve or electronically via an ECAS control box.


The semi-trailer can be fitted with additional safety and technical features:

  • Rear view camera
  • Reflective contour markings
  • Working lights next to the cabinets
  • Reversing lights at the rear
  • EMERGENCY OFF function on each side of the vehicle
  • Automatic braking if cabinet doors open
  • Tyre pressure monitoring system
  • Load-dependent shock absorber control
  • Reverse warning buzzer
  • Reversing area monitoring sensors


Lateral marker lights on the semi-trailer tankers are equipped with LED lights as standard. Benefit: service life of up to 15 years, high light intensity and colour consistency.
