PR1 liquid Flow Switch is suitable for applications with limited demands on accuracy. Its speciality is full flow or no flow. The lowest possible set point in a 50 mm pipe is appr. 100 l/min, the set point increases accordingly with larger dimensions. It can be mounted on pipe-sizes from DN50 up to DN250, the process connection is 25mm thread (through pipe wall).
The paddle aligns fully with the flow and creates a very small pressure drop.
