G1'' stainless variable area flow meter & switch oil 0.1-0.8 l/min
Shows oil flow from 0.1 to 0.8 l/min on a scale. Its normally open contact closes at an adjustable set point. The potential-free reed contact carries no voltage of its own, so it can be wired directly to a PLC (programmable logic controller) input. It switches max. 100 VA, about 0.4 A at 250 V AC; valve or relay coils cause high switch-on currents, so add a contact protection relay (not included). Viscosity compensation keeps the set point valid for oils from 30 to 400 cSt (centistokes). The 1.4571 stainless steel body with female thread is rated to 300 bar (≈4350 psi) and +120 °C (≈248 °F).

Pros:
- Flow reading and switch point in one device
- Potential-free reed contact, no supply voltage needed
- One set point for oils from 30 to 400 cSt
- DIN plug connector (EN 175301-803)
- Any mounting position, preferably with upward flow
Cons:
- Contact protection relay (not included) needed for valve or relay coils
- 50 mm clearance from iron parts needed; not for strong magnetic or induction fields
- Not suitable for liquids with solid or magnetic particles
