The BM26A-7000 is a magnetic level indicator (MLI) for extreme operating conditions and liquid interface applications. The level gauge is particularly suitable for continuous level measurement of high-temperature or high-pressure liquids in chemical, petrochemical and refining processes or in boiler applications of various industries. It is equally suitable for interface measurement in oil/water separators or similar installations. For level monitoring of corrosive products in pressurised tanks up to 40 barg / 580 psig, the PTFE-lined version of the MLI is the instrument of choice.
