SMC's LFE electromagnetic digital flow switch is compact and lightweight. As there are no obstacles or moving parts in the fluid path, the LFE is resistant to clogging. This design only allows a small pressure loss, and a reduced load to the pump, which saves energy. A 3-color, 2-screen indicator is used for better visibility. Instantaneous flow rate is displayed in the upper screen, set values, accumulated flow, peak/bottom value, and line names can be set to display in the lower screen.
