The BM26A-1000 is a magnetic level indicator (MLI) for basic liquid applications. The cost-effective level indicator is particularly suitable for continuous level measurement in water storage tanks, condensate receiver tanks as well as wash and surge tanks for fuels, lubricates, additives or similar chemicals.

The level indicator features a rugged metallic design with the magnetic flaps housed in an IP68 rated, hermetically sealed glass tube. It provides a highly visible local level indication. There is absolutely no power supply needed. However, in applications with more advanced signal output requirements, the MLI can be easily equipped with optional reed switches or a reed-chain level transmitter providing analogue or digital output signals.
