BeskrivelseThe FSW-9000 Series is a flow switch monitor that measures the velocity of the flow. It is ideal for use in measurement and control liquid applications. The FSW-9000 Series provides two output options: a 4 to 20mA analogue output and a PNP/NPN output. For the 4 to 20 mA output, the electronics’ module converts the signal from the probe to a 4 to 20 mA analogue output, which can be used to indicate flow rate. For the PNP/NPN output, the measured flow rate is compared to the setpoint value selected by the user and the switch changes state once the setpoint value has been achieved.
