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.

Product highlights
• Large variety of accessories and options: special materials, valves, insulation, hazardous area approvals, limit switches, level transmitters etc.
• Flaps housed in a hermetically sealed Pyrex® glass tube (IP68 / NEMA 6-6X)
• Rugged stainless steel design: low or no maintenance
• Highly visible level indication works without power supply

Typical applications
• Level applications in non-hazardous and hazardous areas
• Storage and process tanks
