WFS18 Series
Overview
The WFS18 series is a kind of differential pressure flow switch with two adjustable set points. In order to meet various requirements of customers, ACOL company developed the differential pressure flow switch with double adjustable set points for upper-lower limit controlling of differential pressure. When the water flow (differential pressure) in system rises up or falls down to one set value, it will output a warning or sent switch-off signal to automatic control system. It could be applied to water chilling unit、seawater air conditioning、ice-storage air conditioning etc.
