The CF12 Thermal Dispersion Flow Switch with a large aluminum housing (G2) comes standard with a Universal Power Supply: 24Vdc or 85 to 264Vac. This unit offers reliable liquid and gas flow detection ideally suited for just about any Flow/ No Flow application. Unlike the CF12 with either the small nylon housing (N1) or the small aluminum housing (G1), the CF12 with large aluminum housing (G2) comes with two independent SPDT relays (as opposed to just one SPDT relay).
Like all of Sitron’s products, the CF12 can be configured to accommodate our customer’s unique process control requirements. All models can be ordered with a great variety of threaded, flange, or sanitary process connections as well as Halar or epoxy coating for aggressive mediums. The CF12 with large aluminum housing is also offered with extended necks for higher temperature applications up to 120 ºC. And while the CF12 is designed to monitor flow status of liquids and gases, with its no moving parts technology it can also be an ideal solution for liquid level detection.
