A-3
Power Requirements
Loop powered, 12 to 36 VDC.
Output Signals
Analog: field rangeable linear, 4-20 mA output signal, 1000 ohms
maximum loop resistance, selected by user for volumetric flow rate
or mass flow rate.
Pulse: field rangeable volume/pulse output for totalization is a 50-
millisecond duration pulse operating a solid-state relay capable of
switching 40 VDC, 40 mA maximum.
Display
