The MB Series polysulfone rotameters are designed for lower flow requirements; the compact design is particularly suited to confined spacing. MB designs feature a flow range from the model MB1.5 (0.006-0.066 GPM) up to the model MB100 (0.4-4.0 GPM). The MB is offered in polysulfone shells with a variety of union end connections for exacting requirements. MB meters are equipped with GPM, LPH or percent scales.
