The EWN-Y with EFS flow sensor (option) provides accurate real time control & display of dosing rate. The required flow rate is simply input to the pump. Through feedback to the EFS sensor, the pump constantly adjust its speed to maintain the set dosing rate – even under changing temperature, viscosity, or suction & discharge pressure conditions.
The stroke rate can be set with 1spm increments in between 1 and 360spm. The stroke length adjustment further assists fine adjustment that the stroke rate adjustment cannot reach. Contentious precise chemical feeding is now available.
The EWN-Y has the mode of 1:1 operation, multiplier/divider programming control (digital signal), proportional control (analogue signal rigid & variable) and batch mode and can dedicate itself to a particular purpose by selecting a suitable mode. Also, the flow rate indication can be converted from spm to l/h or gph.
The use of the multi voltage circuit design allows the pump to work anywhere in the world.
