The BM26A-8000 is a magnetic level indicator (MLI) for redundant level measurement in liquid applications. It comes in two versions: BM26A-8000-TWIN and BM26A-8000-BI. The BM26A-8000-TWIN consists of a double measuring chamber with one chamber featuring a flapper indication and the other one – equipped with a level transmitter (TDR guided radar, FMCW radar or displacer) – acting as a bypass chamber. The BM26A-8000-BI features a unique measuring chamber with two compartments, one for the OPTIFLEX 7200 transmitter probe and one for the float moving next to it.
By adding a reed-chain transmitter to the TWIN version, the operator can compare the measuring values of the assembled radar level transmitter to those of the reed chain transmitter directly in the control room. This allows for redundant measurement as both technologies operate independently and uninfluenced from each other, providing a high degree of process safety in critical applications. The BM26A-8000 can thus be the ideal choice for steam cycle applications in power plants, storage tanks with dangerous chemicals, separators in the oil and gas industry as well as a wide range of other level and interface applications. Depending on the selected configuration, the magnetic level indicator can also be used in safety-related applications up to SIL2/3.
