Flow Switch รุ่น F30 SERIES
คุณลักษณะ
The F30 Pump Controller offers a far better approach. Thepump starts on either flow or pressure drop, as soon as there is a modest demand. When demand ceases the controller continues to run the pump for a length of time, sufficient to recharge the system's air cell. Such a system allows the selection of a pump that has a flat curve and delivers a steady constant pressure over widely carying flows. An air cell with a very small draw-off can be used; as there only has to be sufficient stored pressure to re-actuate the F30 controller the next time there is a demand. With the F30 system the external pressure switch is set to start the pump at a pressure only maginally higher than the systen's static pressure. If the demand is too low to actuate the F30's paddle, or if for any close and signal the F30 to start the pump. The F30 than runs the pump for a preset time, recharges the air cell, switch to standby mode and waits for a further demand.
