Bühler NS 1 externally mounted level gauge, 280 mm, with an electrical contact for the low level.
Bühler NS 1 series level gauge, mounted outside the tank as a bypass, with G1/2 connection. The oil rises in a tube parallel to the tank so the level can be seen from outside; a magnetic contact gives the low-level electrical signal.
The NS 1-G1/2-AM data sheet is in the attachments. Check the distance between the tank connections and the contact type (opening or closing at low level) expected by the control panel.
