This product also has a built-in 4-20-milliampere analog power output signal which provides analog output of the measured values. It is used as follows:
● Outputs include flow rate, flow velocity, upstream temperature, downstream temperature, liquid sound velocity, and upstream/downstream temperature differential.
● Upper and lower limits can be customized to provide the required range of output.
● The 4-20mA is 3-wire wiring. As long as power supplied by device DC, the external power supply is no need for 4-20mA terminal. As below image, please refer to do wiring.
