Flow switch DW-K / 0.4 L/min.

For example, the DW-K is designed for monitoring coolant recirculation systems with low flow rates. Compact and ideal for switching points between 0.1 and 2.5 l/min. In accordance with the wishes and requirements of our customers. The principle: A special piston, equipped with permanent magnets, is held in a certain position by a spring. Depending on the flow rate, the medium slides the piston against the force of the spring. If the current exceeds or falls below the current switching point, the reed switch outside the medium is activated contactlessly via the permanent magnet. The construction is absolutely leak-proof and can be easily disassembled for possible cleaning. The special piston divided into a measuring and guide section combines precise switching with high reliability.
