The CF420 model is a flow transmitter that measures the velocity of the flow. It is ideal for use in measurement and control applications. The CF420 provides two output options; a 4-20mA analog output and a PNP/NPN output. For the 4-20mA 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/NPN output, the measured flow rate is compared to the set point value selected by the user and the switch changes state once the set point value has been achieved.
