    Flow Switch AL 250v

    Flow switches are used in liquid flow lines carrying water, ethylene glycol or any other fluid that is non-harmful to brass or phosphor bronze. They are used to sense the flow of liquid for the purpose of alarming or activating a lockout circuit should the flow stop for any reason. Commonly used in chillers or water sourced heat pumps they are responsible for shutting down the plant should the flow rate fall below a predetermined value and there is a risk of the fluid freezing in the evaporator heat evacuator.
