Intelligent Flow Totalizer Features:

  • can be calculated and accumulated automatically mass flow rate or volumetric flow rate;
  • can be set to instantaneous flow rate function, resection of small signals  (instantaneous flow rate is less than the set value flow is not cumulative)
  • Set the flow control (cumulative value is greater than the set value output flow control signals)
  • Can be set to instantaneous flow rate upper/lower limit alarming functions
  • Programmable following several sensor types

                   P input for differential pressure type flow sensor

                   P, T input for differential pressure flow sensors, temperature sensors

  •         P-P input for differential pressure flow sensors, pressure sensors
            P and P, T input for differential pressure flow sensors, pressure sensors, temperature sensors
            f  input for frequency of flow sensor Input for frequency
  •         f and P flow sensors, pressure sensors
            f, P and T input for frequency of flow sensors, pressure sensors, temperature sensors
