The Gems Sensors & Controls GPM-FS200 Flow Switch (FS200) is a flow-sensing switch designed to monitor system flow and trigger a circuit change in response to detected movement. It carries a Class 1 electrical rating and a pilot duty of 20 VA, with an operating voltage range from 50 to 240 VAC. This combination makes the GPM-FS200 suitable for integration into established control schemes that rely on reliable flow detection across a wide AC voltage span.
