HRT1 Rate Indicator/Totalizer with HART® Communication Protocol Product Bulletin HRT 1-111B The Turbine Flowmeter Company ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ HART® Field Communication Protocol. 5 Digit Rate, 8 Digit Totalizer LCD display with configurable decimal point location. 8 Digit, Non-resettable Grand Total display. Pulse Input supports turbine as well as many other pulse generating flowmeters. 4-20mA Analog Output. Up to 20 Point Linearization. Optional Scaled Pulse Output representing an increment of volume for each pulse. Two Optional Alarm Outputs configurable for Rate and Total. Magnetically operated reed switch for Total reset. Internal battery backup. Configuration and Grand Total stored in non-volatile memory. Grand Total saved once per minute. 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. GENERAL Linearization: Up to 20 points. TOTAL DISPLAY: 8 Digits 0.26” high. Resettable. Decimal Points: Configurable for 0, .0, .00 or .000 for rate and total. Total Units: GAL, LIT, FT3, M3, BBL &“blank”. Accuracy: Total: ±1 count, Rate: ±0.01% GRAND TOTAL: INPUTS 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. Magnetic Pickup: RATE DISPLAY: 5 Digits 0.5” High, Display updates once every two seconds. Rate Units: /SEC, /MIN, /HR, & /DAY.
