Communication with the FTL protocol

PreciCONTROLPreciFUELand PreciGASsupport the open and normed Fuel Truck Link (FTL) communication protocol and comes as a standard.

The FTL communication protocol EN 15969 is the manufacturer independent standard in the industry. FTL derived from the fuel tanker industry and was jointly developed by major oils and system manufactures.

Supported Vision

Alfons Haar supports the idea of mix and match capabilities of delivery or refuelling system hardware and software solutions for the equal benefit of operators and solution providers.

Our Mission

To make things easier and reliable, Alfons Haar actively contributes to the FTL Standard development because it prevents unnecessary developments and eliminates operator’s Integration problems caused with proprietary protocols.
