What is T-AS Series Paddle Switch?

This device serves as a flow monitor via magnetic triggering of a reed switch by liquid flow. Basically the device consists of a brass body, tube housing, paddle arm, balance arm, magnet and a reed switch assembly. The liquid fluid which flows inside the body moves the flat surface of the paddle arm and therefore a magnet which is assembled at the end of same paddle arm. Moved magnet triggers the reed switch which is assembled in the brass tube. By this way reed switch contact changes its situation from open to close or close to open according to brass tube position. This situation change is transmitted via a cable to a control panel which final user sees whether there is a flow or not in the line.
