     Continuously powered LCD display
          Resettable Total: 7 digits with 10mm (0.4'') high digits Resettable from front panel
          Accumulated Total: Displayed when the Accumulated Total button is pressed
     Rate: 4 digits with 8.5mm (0.33'') high digits
     Span: The units of measure per time base (eg. gallons/sec) is programmable up to 999,999
     Decimal Points: Decimal point positions are fully programmable for both rate and total
     Time base: Span can be programmed in units per second, minute, hour or day
     Signal Type: 4-20mA
     4-20mA Input:
         Resolution and Linearity: 0.05% of span
         Accuracy: 0.05% of span at 25°C; 0.1% (typ) of span, full temperature range

         Connection: Two wire
         Voltage Drop: 2.5 volts maximum
     Alarm/Pulse Outputs:
         Type: Two solid state relay outputs suitable for driving DC solenoids or external relays. The outputs provide high and low flow alrms; or pulse output and low flow alarm.
         Switching Power: 200mA. 30VDC maximum.
         Saturation Voltage: 0.8VDC typical across the output in the ''on'' state
         Isolation: Both outputs are seperately opto-isolated.
         Pulse Duration (for pulse output):
               a. 1ms if output frequency > 50Hz
               b. 10ms if output frequency is 5...50Hz
               c. 100ms if output frequency is < 5Hz.
