    ® For pressure measurements, the LD400 HART includes an option list with the most common units. The internal reference unit is inH O @ 20 ºC; should the desired unit be other than this one, it will be automatically converted using conversion factors included in Table 4.1.
  • Page 56 Should a special unit other than those presented on Table 4.2 be required, the LD400 HART ® allows the user to create a new unit by entering up to 5 alphanumeric digits. The LD400 HART includes an internal feature to enable and disable the User Unit.

  • Page 57: Transfer Function For Flow Measurement

    This gives a more stable reading at low flows. ® In order to find the square root, the LD400 HART configurable parameters are: cutoff point defined at a certain pressure expressed as % and the cutoff mode, hard or bumpless.

  • Page 58: Totalization Configuration

    For example, in tank maneuvering there are several pipes where the ® direction of the fluid may vary. In this case, LD400 HART has the bidirectional flow measurement function. This function treats the flow, no matter what its direction is, as if it were positive. Thus, it is possible to extract the square root and measure the bidirectional flow.
  • Page 59 Configuration The method uses such totalization and, through three parameters (MAXIMUM FLOWRATE, TOTAL INCREMENT and TOTAL UNIT), converts it to the user-defined totalizing unit:  MAXIMUM FLOW RATE - this is the maximum flow rate expressed in volume or mass units per second, corresponding to the measurement (PV%=100%).
