The BM26A-3000 is a magnetic level indicator (MLI) for corrosive liquids. Made from corrosion resistant PVC, PP or PVDF, the level gauge is the perfect fit for continuous and safe level measurement in plastic or lined storage tanks, reactors, fermentation vessels or containers with aggressive chemicals such as sulphuric acid.

The float of the level indicator features the same material as selected for the gauge. Its flaps are housed in an IP68 rated, hermetically sealed glass tube. The MLI provides highly visible local level indication. There is absolutely no power supply needed. However, in applications with more advanced signal output requirements, the BM26A-3000 can be easily equipped with optional reed switches or a reed-chain level transmitter providing analogue or digital output signals.
