The CF420RM Remote Mounted Thermal Dispersion Flow Transmitter is available in two versions: CF420RMDC (+/-24Vdc) or CF420RMAC (85 to 264Vac). Both of these models offer reliable liquid flow monitoring, with the flexibility of a separate panel mountable analog/relay controller. This model is often an ideal solution when the point of installation is a very confined space or where the user prefers panel mounted electronics.
Like all of Sitron’s products, the CF420RM 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.
