2-Color Display Digital Flow Switch Series PFMB Digital flow switch to save energy! Flow control is necessary for promoting energy saving in any application. Saving energy starts from numerical control of the flow consumption of equipment and lines and clarification of the purpose and effect. Main line flow control Flow control for each branch line Remote control is possible with accumulated pulse. Digital display allows visualization of flow rate. 2-color display, Improved visibility Refer to the WEB catalog or the Best Pneumatics No. 3 for details of multi-counter CEU5.
