PR1

Paddle Switch PR1 is using the liquid flow to activate the spring supported paddle and the micro-switch to give an alarm if the flow stops or starts. The installation is simple as you can cut the paddle to the desired length on site according to the actual pipe size. The paddle aligns fully with the flow and creates a very small pressure drop. The function works only in one flow direction.
Paddle Switch PR1M is certified for marine applications according to DNV rules for classification – Ships, offshore units, and high-speed and light craft.
