FUNCTION DESCRIPTION
Type GWS limit indicator GWG
In accordance with the regulations for protecting waterways against pollution, overfilling of
tanks used to store liquid fuels must be prevented. This basic requirement is met if road
tankers are equipped with an overfill prevention mechanism (EN 13616: Steuereinrichtung am
Straßentankfahrzeug) automatically preventing the tanks from being overfilled in cooperation
with a limit indicator specified according to worksheet DWA-A 779, DWA-A 791-1, DIN 4755
and VdTÜV leaflet Tank systems 964, respectively.
The GWG series limit indicators meet the requirement according to harmonised
EN 13616 as sensors for tanks with current interface as part of a type B1 overfill protection
device and meet the withdrawn TrbF 511 regarding their design. GOK limit indicators meet
the demands on the condition of both EN 13616 and TrbF 511.
