Description
Magnetic bypass level indicator for liquid and liquid-liquid interface applications
The BM 26 A is a universal bypass level indicator with IP68 / NEMA 6-6X indicator rail.
The device indicates liquid level or liquid-liquid interface via a float in the bypass chamber which is magnetically coupled with the magnets of an external mount rail with flappers or index.
The magnetic level indicator operates over a wide temperature range and high pressure. It is also the perfect device when no power is available.
