The CF12 Thermal Dispersion Flow Switch with a small aluminum housing (G1) is available in two versions: CF12DC (+/-24Vdc) or CF12AC (85 to 264Vac). Both of these models offer reliable liquid and gas flow detection ideally suited for just about any Flow/ No Flow application with a small robust aluminum housing. The G1 Aluminum housing can also be ordered with an acrylic window for active viewing of flow status without having to remove the housing cover.
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 small 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.
