Thermal Dispersion Mass Flow Meter

Thermal Dispersion Mass Flow Switch

Sitron introduced its first Thermal Dispersion Flow Switch in 1995. Thermal Desertion technology enables the detection of flow of gases and liquids without moving parts and with a much longer life span compared to other technologies. While our flow switch has been updated and improved over the years, one thing has not changed: The CF12 series continues to offer maintenance-free reliability for liquid and gas flow detection for most applications at a very competitive price.
Like all Sitron products the CF12 can be configured according to the unique control needs of our customers. Offered in Fiberglass Reinforced Nylon, Aluminum or 316 Stainless Steel. All models can be purchased in a wide range of process connections such as threads, flanges or sanitary as well as with Halar or Epoxy coating for aggressive media or even with the process sensor separate from the electronics. While the CF12 is designed to monitor the flow status of liquids and gases, it is also commonly used for liquid level detection.
