2.3.2 Analog output

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 4-20-milliampere signal is a passive signal that requires an external power source. Please note that an independent power supply must be used. The 4-20-milliampere output signal cannot share power with the instrument; otherwise it may cause instrument burnout! Please wire the positive and negative terminals correctly. The external power supply voltage range is 12 ~ 30 volts DC. 12 volts is recommended; higher voltages may cause the temperature of the instrument to rise.
