Figure 1-3 shows a sample system configuration in which the instantaneous
flow rate measured by the unit is output with a 4 - 20 mA DC analog signal.
In this system, the DC power supply that transmits the analog signal is inte-
grated into the unit, which can output the analog signal directly to the host
control system.
