Featuring 5 digits of rate and 8 digits of total, the HRT1 is a loop powered indicator capable of accepting magnetic
pickup, DC pulse or switch closure inputs. The HRT1 uses the 4-20mA loop to provide power when this output is
used and to provide the HART® communication link.

 

TOTAL DISPLAY:
8 Digits 0.26” high. Resettable
Total Units: GAL, LIT, FT3, M3, BBL &“blank”
GRAND TOTAL:
8 Digits 0.26” high, Non-resettable. Value stored once per
minute in non-volatile memory. Grand Total is displayed for
15 seconds after pressing the  button.
RATE DISPLAY:
5 Digits 0.5” High, Display updates once every two seconds
Rate Units: /SEC /MIN /HR /DAY
K-factor: The pulses per unit of Total (e.g. pulses/gallon) are
configurable in the range 0.001 to 99,999,999
Linearization: Up to 20 points
Decimal Points: Configurable for 0, .0, .00 or .000 for
rate and total
Accuracy: Total: ±1 count, Rate: ±0.01%
