Pressure leak detector with re-filling function from a stationary connected nitrogen bottle or a compressed gas network (operating mode C = continuous). With optional function for operating mode I (= interval) without automatic re-filling function.
Operating mode C (formerly S) for aboveground and underground double-walled pipes.
Operating mode I (formerly M) only for applications without temperature variations of more than +/-10 °C (e.g. double-walled pipes installed underground or indoors; no hot media).
With digital manometer (M).
TYPES:
DLR-G 1 M, DLR-G 2 M, DLR-G 3 M and in 1 bar steps up to DLR-G 18 M
P: weatherproof housing
Si: service indication (adjustable 1 to 63 months)
PIPES:
- Double-walled sufficiently pressure-resistant pipes and fittings made of metal or plastic in factory or on-site construction
