Description

The CF420 is a flow Transmitter that measures the velocity of liquid flows. The CF420 provides two output options; a 4-20mA output and a PNP switch output. The electronics module converts the signal from the probe to a 4…20mA analog output, which can be used to indicate flow rate. For the PNP output, the measured flow rate is compared to the field calibrated set point value and the Switch changes state once the set point value has been achieved. A chain of 8 LED’s gives the user a visual indication of the flow rate as well as set point status, and one di-chromatic LED indicates switch point status. Like all of Sitron’s products, the CF420 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 or even with separate electronics and process sensor.
