Mini flow switch type: DW-K

Mini flow switch type: DW-K

Flow switches with reed contact for liquids and gases for low flow rate situations

The DW-K is designed to monitor low-flow refrigerant circulation systems. The construction is very compact and ideal for switching points between 0.1 and 2.5 l/min. For operation, a special piston fitted with a permanent magnet is held in position by a spring. The material sets the piston in motion against the spring pressure, depending on the velocity of the flow. When under or over the switching point threshold, the reed contact outside the material is activated. The construction is waterproof and detachable, if necessary. In addition, the DW-K flow switch is virtually insensitive to contamination and scale attack.
